128 means engine ECU. Fail 07 is your failure mode identifier such as a short or open circuit, for example. You will need to go back into the readout and scroll through to get the SID or PID (SPN) numbers associated with that fault. Neither of those numbers are your fault code that you posted. The fault code will have an SID, PID, or SPN number. That is the number we will need to determine your file code. It's a pleasure to help anyway I can.

codes are gone at this time what I had pulled in this order was diag 1 fault 1 ecu ld 027 fail 07
Technician: Daniel Wilson,
 replied 3 years ago

Fault 2636

SID 27

SPN 641

Fault (FMI) 9

VGT Actuator Driver Circuit - Abnormal Update Rate. No communications on the J1939 data link between the engine ECM and the smart VGT controller.

This fault code logs when the primary engine ECM did not receive valid J1939 information from the VGT actuator.

Troubleshoot high inactive counts of Fault Code 2636 as an active fault code.

Possible causes:

1)The VGT actuator is not receiving power from the ECM. This could be caused by an open circuit in the power supply wire or low voltage supplied by the primary engine ECM
2)Coolant entering VGT actuator and corroding circuit board
3)Rapid cycling of the keyswitch
4)An open return circuit on the VGT actuator circuit
5)An open or short circuit on the J1939 data link circuit between the ECM and VGT actuator
6)Intermittent communications between the VGT actuator and the primary engine ECM on the J1939 data link
7)Connector pins are not installed in the appropriate locations specified by the wiring schematic
8)A damaged termination resistor in the engine data link harness
9)A damaged engine ECM.

Possible repairs:

1)Replace the VGT actuator.
2)Repair or replace the engine harness
3)Replace the ECM
4)Repair or replace the engine harness.
5)Replace the J1939 data link termination resistor.
