I have a CAT TH360B with the following codes: 039 1251-08,

I have a CAT...

I have a CAT TH360B with the following codes:(###) ###-####08, 1127-02, 1128-02, 1529-02, 1824-03, 1824-04, 0191-02, 0246-12. What am I looking at? Output speed sensor? Rail sensor?

Mechanic's Assistant: What is the complete model and serial number of your machine?

I don't have the serial handy. But that is the model number, and every time I look up a part there is only one serial sequence to choose from.

Mechanic's Assistant: Anything else you want the construction mechanic to know before I connect you?

Help!

MID 039 - CID 1251 - FMI 08

This diagnostic code is associated with the R-terminal connector of the alternator. The FMI 08 means that the ECM has determined that the signal from the terminal is abnormal.

The possible causes of this diagnostic code are listed below:

  • The alternator has failed.

     

  • Intermittent connections or poor connections

  • Mechanical devices are loose.

     

  • The ECM has failed. This is unlikely

MID 039 - CID 1127 - FMI 02

This diagnostic code is recorded when the ECM records an erratic signal or an intermittent signal from the position sensor for the joystick control. The sensor controls the Y axis of the joystick control. There could also be a short to the +battery circuit, a short to ground, or an open circuit. The position sensor is a PWM sensor. The signal wire for the position sensor connects to connector contact J2-32 (wire 781-PK) of the ECM.

The possible causes for this diagnostic code are listed:

  • The signal circuit is open.

     

  • The +battery circuit from the electrical system to the sensor is open.

     

  • The signal circuit is shorted to the +battery circuit.

     

  • The signal circuit is shorted to ground.

MID 039 - CID 1128 - FMI 02

The sensor controls the X axis of the joystick. This diagnostic code is recorded when the ECM records an erratic signal or an intermittent signal from the position sensor for the joystick control. There could also be a short to the +battery circuit, a short to ground, or an open circuit.

The position sensor is a PWM sensor. The signal wire for the position sensor connects to connector contact J2-40 (wire 782-GY) of the ECM.

The possible causes for this diagnostic code are listed:

  • The signal circuit is open.

     

  • The +battery circuit from the electrical system to the sensor is open.

     

  • The signal circuit is shorted to the +battery circuit.

     

  • The signal circuit is shorted to ground.
