Hello,
the only way customers can see the codes is to have the advanced monitor installed in the right upper console.
If you have this feature, please post the full serial number and I can help further.
Common issues are with speed sensors and hand control sensors.
Inspect all wiring to the hand control and the speed sensors located in each drive motor. Harness is easily damaged to the speed sensor. It is only tied to the hoses from the frame to the drive motors.

Investigate the cause. If no additional alert indicators are illuminated, contact your Caterpillar dealer or refer to the service manual. Level 2 - If the alert indicator is flashing and there is no audible alarm, severe component damage could occur. Change your operation or perform the indicated maintenance. Level 3 - If the alert indicator is flashing and there is an audible alarm, injury to the operator or severe component damage could occur. Stop the machine immediately and stop the engine. 2 - Alternator Output This alert indicator will light if there is a malfunction in the electrical system. If this alert indicator comes on, the system voltage is too high for normal machine operation or too low for normal machine operation.If electrical loads are high and the engine speed is near low idle, increase the engine speed to high idle. This will generate more output from the alternator. If the alert indicator for the electrical system turns off within one minute, the electrical system is probably operating in a normal manner. However, the electrical system may be overloaded during periods of low engine speeds.Increase the engine idle speed with the governor lever in order to compensate for a higher electrical load on the system.If this procedure does not cause the alert indicator to turn off, move to a convenient location. Investigate the cause (loose alternator belt, broken alternator belt, faulty batteries, etc).3 - Parking Brake This alert indicator will light when the parking brake is engaged. The alert indicator should come on during start-up. The alert indicator should go out when the parking brake is disengaged.4 - Seat Belt and Armrests This alert indicator will light when the armrests are in the RAISED position. The alert indicator will light when the operator gets out of the operator seat. The alert indicator should go out when the operator is in the operator seat and the armrests are in the LOWERED position.5 - Hydraulic High Flow This alert indicator will light when the high flow hydraulic system is activated.Note: The thumb wheel on the joystick must be fully displaced in order to activate the high flow hydraulic system.Note: High flow mode requires an electrical connection that is located on the loader arm. Refer to Operation and Maintenance Manual, "Work Tool Coupler Operation" or Operation and Maintenance Manual, "Work Tool Operation" for additional details.6 - Continuous Flow This alert indicator will light when the continuous flow is activated.7 - Work Tool System This alert indicator will light red when the work tool lockout control is activated. This alert indicator will light amber when the interlock override is activated. 8 - Hydraulics This alert indicator will light red and an audible alert will sound when the temperature of the hydraulic oil is too high. If this indicator comes on, stop the machine immediately. Stop the engine and investigate the problem. This indicator will light amber when the hydraulic oil filter is not functioning properly. Stop the machine and replace the oil filter. The indicator will stay on until the hydraulic oil has warmed up. Do not operate the machine until the light turns off. 9 - Glow Plug Starting Aid With the engine start switch in the ON position, this alert indicator will light when the glow plugs are activated. The operator should wait until this light is no longer illuminated before starting the machine. Refer to Operation and Maintenance Manual, "Engine Starting" for more information about the glow plug starting aid.10 - Engine This alert indicator will light red and an audible alert will sound when the engine coolant temperature is too high. If this alert indicator comes on, stop the machine immediately. Stop the engine and investigate the cause. This alert indicator will light red and an audible alert will sound when the engine oil pressure is low. If this alert indicator comes on, stop the machine immediately. Stop the engine and investigate the cause. This alert indicator will light amber when the air cleaner indicator is activated. Stop the machine and service the air cleaner. 11 - Machine Security System This alert indicator will light when the Machine Security System is activated. Refer to "Machine Security System" for more details about the security system.12 - Two-Speed Control This alert indicator will light when rabbit mode is selected with the two speed control.13 - Creeper Control This alert indicator will light when creeper mode is selected.14 - Ride Control This alert indicator will light when the Ride Control switch is "ON" and the necessary ground speed is reached for Ride Control activation.15 - Joystick Control Pattern 1 If your machine is equipped with a Selectable Control Pattern, this alert indicator will light when the Caterpillar Joystick Control Pattern is activated.Note: Refer to Operation and Maintenance Manual, "Operator Controls - Joystick Controls" for information about the joystick control patterns. If your machine does not have the Dedicated Control Pattern, the light will flash until a selection is made.16 - Alternate Joystick Control Pattern 2 If your machine is equipped with a Selectable Control Pattern, this alert indicator will light when the Alternate Joystick Control Pattern is activated.Note: Refer to Operation and Maintenance Manual, "Operator Controls - Joystick Controls" for information about the joystick control patterns. If your machine does not have the Dedicated Control Pattern, the light will flash until a selection is made.The Service Mode allows the viewing and the troubleshooting of various systems. The Service Mode is one of two modes that are displayed on the Digital Data Display window that is located on the right side Instrument Cluster (Cab Display). Navigating the Service Modes Enter the Service ModeEnter the Service Mode screen by pressing the Function Select button and simultaneously pressing the Scroll Up button for 3 seconds. Exit the Service ModeExit the Service Mode screen by pressing the Function Select button and simultaneously pressing the Scroll Up button for 3 seconds. This action will return the Digital Data display to Operator Mode 0 and the engine speed will be displayed. Navigate the Service Mode ScreensNavigate through the Service Mode screens by pressing the Scroll Up button or by pressing the Scroll Down button.The Service Mode has the following seven screens. Several of these seven screens contain lower-level screens. Press the Scroll Up button in order to scroll one by one through items of these lower-level screens. Service Mode 0Service Mode 1 displays the Active Diagnostics. Service Mode 1Service Mode 2 displays the Logged Diagnostic. Service Mode 2Service Mode 3 displays the Active Events. Service Mode 3Service Mode 4 displays the Logged Events. DiagnosticsThe Diagnostic Service Modes and the Event Codes are used by service personnel in order to troubleshoot machine systems. The DiagnosticService Modes and the Event Codes are screens 1 through 4. See Table 1. Table 1Diagnostic Code Screens Service Modes Number Description 0 Variable With the Number of Active Diagnostics, Logged Diagnostics, and Events Active Diagnostics 1 Variable With the Number of Active Diagnostics, Logged Diagnostics, and Events Logged Diagnostics 2 Variable With the Number of Active Diagnostics, Logged Diagnostics, and Events Active Events 3 Variable With the Number of Active Diagnostics, Logged Diagnostics, and Events Logged Events The main display module detects diagnostic codes that occur with sensor inputs, sender inputs, and main display module outputs. The main display module must be in the normal mode to detect those diagnostic codes. A diagnostic code is detected when the signal is outside a valid range. The main display module then records the diagnostic code. The diagnostic code remains stored for future reference.The main display module detects diagnostic codes and the main display module diagnoses problems in the following circuits: Display output modules Action alarm output Action lamp output Note: The main display module does not detect problems with the switch inputs.Service personnel can see the diagnostic codes and service personnel can troubleshoot the diagnostic codes when the main display module has detected a problem. All detected failures are shown in the display area as diagnostic codes.The diagnostics of the monitoring system are available to assist with the troubleshooting of failures when the main display module is placed in service mode. A diagnostic code is used to specify each problem. The diagnostic code is made up of three identifiers (MID, CID, and FMI). These identifiers are shown in the display area. The display area continuously changes between the following identifiers when the diagnosticcode is on hold:Module Identifier (MID) - The MID is a three-digit code that is shown on the display area. The MID is shown for approximately one second before the diagnostic code is displayed. The ECM that has diagnosed the failure is logged by the MID. An example of the MID follows: Machine ECM ... 039See the table for the Module Identifier (MID) on the Electrical System Schematic for the machine that is being serviced for the most complete list. In order to troubleshoot diagnostic codes, use the Service Manual for the control that detected the problem.Component Identifier (CID) - The components that have failed are noted by the CID. The following components are examples: Transmission oil temperature sensor Speed sensor Action lamp Boost pressure sensor The CID is a four-digit code that is shown on the six-digit display area of the Digital Data window. The CID and the FMI are shown together after the MID has been displayed.Failure Mode Identifier (FMI) - The FMI reports the type of failure that has occurred. The FMI is a two-digit code that is shown on the six-digit display area. The CID and the FMI are shown after the MID is displayed. The CID and the FMI are separated by a decimal point ".". See Troubleshooting, " Diagnostic Code List". The table for the Module Identifier (MID) on the Electrical System Schematic will show a list of FMIs for the main display module. Examples of the FMIs follow: Voltage above normal Current below normal Abnormal frequency When the main display module enters the service mode, the MID, the CID, and the FMI are shown. At this time, the diagnostic code that is shown is on hold. The display area continuously changes between the following identifiers when the diagnostic code is on hold: MID CID FMI The display is maintained as long as the service and clear inputs remain open. Troubleshooting is performed while the diagnostic code is on hold.Note: The display shows "- - - -" when the main display module has no diagnostic codes.All diagnostic codes are shown one at a time in the display area when the diagnostic codes are scrolling. When the main display module is in the service mode, grounding the service input causes the display to scroll. This action will momentarily show the MID. The display shows the CID and FMI that corresponds. When the desired diagnostic code shows up, removing the ground from the service input stops the scrolling. The diagnostic code showing then is on hold for review.Diagnostics are provided in order to assist service personnel during troubleshooting of intermittent diagnostic codes. The service code indicator ("SERV CODE") is shown when a diagnostic code is present. This feature can aid in the troubleshooting of intermittent diagnosticcodes. The service code indicator changes from "SERV CODE" that is OFF to "SERV CODE" that is ON. The changes occur when thediagnostic code changes status. When a diagnostic code is on hold for a problem, the action alarm SOUNDS briefly during the change of status. These diagnostics signal the service personnel while inspections are performed. These diagnostics assist in troubleshooting intermittentdiagnostic codes by one service person.The memory of the main display module saves a diagnostic code until the code is cleared. The main display module does not allow clearing of a diagnostic code that corresponds to a diagnostic code which is present.

Right Side Instrument Cluster (optional)Item (6) is the Instrument Cluster that is located in the right side panel. This Instrument Cluster is referred to in Cat Electronic Technician (ET) as the Cab Display. This Instrument Cluster contains the following:(7) This gauge displays the temperature of the engine coolant.(8) This gauge displays the temperature of the hydraulic oil that is in the hydraulic tank.(10) This Digital Data window displays the following: Job Clock Diagnostics (CID-FMI) Machine Parameters Component Status Units Engine RPM System Voltage Creep Mode Digital Data Selection Momentary push buttons (11), (12) and (13) allow the operator to navigate through the information that is displayed on the Digital Data window (10) .(11) This is the Scroll Up button. This button permits the service technician to scroll through the data that is displayed.(12) This is the Scroll Down button. This button permits the service technician to scroll through the data that is displayed.(13) This is the Function Select button. Pressing this button for three seconds simultaneously with a Scroll "Up" button permits the selection of an operator mode or a service mode.This should allow you to view the codes. Once you have found the codes, please post them here and we can pinpoint the issue. Be sure to mark which are Active, Logged and/or Events. DO NOT erase any codes. You may need them later to isolate another problem area. You may need to operate the machine to trigger the codes to become active. It is best to do this so you can identify which warnings are on and which codes are active. This saves a lot of time and is better than guessing where the problem is located.

OH sorry, I see the breaks now. My other answer page did not separate the correctly.
Sorry for all the information sent through. It should have stayed together like it was on my page.
The code you should check is the 1705-5 code, you forward solenoid is an active fault.
Here are the details to check this code.
Right Drive (Forward) Pump Solenoid Circuit
This diagnostic code is recorded when the ECM reads the current of the solenoid as being below normal.
The possible causes are listed:
The energize circuit of the solenoid is open.
The return circuit of the solenoid is open.
The solenoid has failed.
The ECM has failed. This is unlikely.
Note: The following test procedure may create other diagnostic codes. Clear the diagnostic codes when the problem has been corrected. Verify that cid 1705 fmi 05 is active before performing this procedure.
System Response:
The diagnostic will generate a cid 1705 fmi 05 level 2 warning. If the machine is traveling in reverse, the machine will be brought to a stop. If the machine is moving forward, the machine travel will be limited to half speed. A level 3 warning will be active E696 Opposite Machine Movement Commands Disabled.
Test Step 1. CHECK THE SOLENOID.
Turn the key start switch to the ON position. DO NOT start the engine.
Disconnect the machine harness from the solenoid.
At the machine harness connector for the solenoid, place a jumper wire from contact 1 (wire K947-YL) to contact 2 (wire H801-PU).
Observe the status of the diagnostic code.
Expected Result:
cid 1705 fmi 05 is active before the jumper wire is installed. Once the jumper is installed, cid 1706 fmi 06 is active.
Results:
YES - The circuit is correct. The solenoid has failed.
Repair: Inspect the harness to the solenoid for any failures. Disconnecting the solenoid and adding a jumper wire could temporarily cause the short to be removed from the harness. Reconnect the solenoid in order to verify that the diagnostic code has become active again. Repeat the step in order to verify that the solenoid has failed. Replace the solenoid.
STOP
NO - cid 1705 fmi 05 remains active. Proceed to test step 2.
Test Step 2. CHECK THE SOLENOID CIRCUIT FOR AN OPEN.
Disconnect the negative battery cable and turn the key start switch to the OFF position.
Disconnect the J1 machine harness connector from the ECM.
At the machine harness connector for the solenoid, the jumper wire remains installed.
At J1 machine harness connector, measure the resistance from contact J1-50 (wire H801-PU) to J1-51 (wire K947-YL).
Expected Result:
The resistance should be less than 5 ohms.
Results:
YES - The resistance is less than 5 ohms. The machine harness is correct. Proceed to test step 3.
NO - The resistance measurement is NOT correct. There is an open circuit in the machine harness.
Repair: The open is in the wire for the solenoid signal or in wire (H801-PU) of the machine harness. Repair the machine harness or replace the machine harness.
STOP
Test Step 3. CHECK IF THE DIAGNOSTIC CODE REMAINS.
Inspect the contacts and clean the contacts of the harness connectors.
Reconnect all harness connectors.
Reconnect the negative battery cable and turn the key start switch to the ON position.
Clear all inactive diagnostic codes.
Operate the machine.
Stop the machine and place the parking brake switch in the ON position.
Check if the diagnostic code for the solenoid is active.
Expected Result:
The diagnostic code is NO longer active.
Results:
YES - The diagnostic code is NO longer active. The diagnostic code does not exist at this time.
Repair: The initial diagnostic code was probably caused by a poor electrical connection or a short at one of the harness connectors that was disconnected and reconnected. Resume normal machine operation.
STOP
NO - The diagnostic code has not been corrected. The ECM may have failed.
Repair: It is unlikely that the ECM has failed. Exit this procedure and perform this procedure again. Also, recheck if the diagnostic indicator is illuminated for this diagnostic code. If the cause of the diagnostic code is not found, replace the ECM. See Testing and Adjusting, "Electronic Control Module (ECM) - Replace".

Also, the E875 -2 code is active EVENT code.
This may only be from leaving the key on while testing.
With all the other codes shown, it looks like you have been unplugging everything with the key on.
Since they are all logged, I would not worry about those codes yet.
I posted the whole event list for you to see what they all meant.
The ones for the speed sensors (E570 and E571) could be related to a different issue.
The others are showing the machine abuse.
Please let me know if you need more help on this.
Thanks, Donnie

Thanks for the great information.
The problem was in the purple H801 circuit it had two spots that where broken causino intermittent connection. Replaced the terminal at the solenoid and all is good.
I did suggest that the lower main harnesses going to the drive solenoids be replaced.
Thanks again for your help.
