Pinpoint Test B: TCM Internal Faults
WARNING: This page is about a different variant/trim than selected.
- Refer to TRANSMISSION CONTROLS - TR9070
for schematic and connector information.
Normal Operation and Fault Conditions
The TCM runs routine diagnostic checks on itself. If it detects a fault with internal hardware, programming or performance, it will set a DTC.
DTC Fault Trigger Conditions
DTC Description Fault Trigger Condition TCM P0602:00 Powertrain Control Module Programming Error: No Sub Type Information The TCM sets this DTC when it detects a TCM programming fault. TCM P0604:00 Internal Control Module Random Access Memory (RAM) Error: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM RAM. TCM P0605:00 Internal Control Module Read Only Memory (ROM) Error: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM ROM. TCM P0606:00 Control Module Processor: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM processor. TCM P0607:00 Control Module Performance: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM. TCM P060A:00 Internal Control Module Monitoring Processor Performance: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM. TCM P060B:00 Internal Control Module A/D Processing Performance: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM. TCM P060C:00 Internal Control Module Main Processor Performance: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM main processor. TCM P0610:00 Control Module Vehicle Options Error: No Sub Type Information The TCM sets this DTC when it detects a difference in the programmed vehicle equipment compared to the actual vehicle equipment. TCM P0613:00 TCM Processor: No Sub Type Information The TCM sets this DTC when it detects a fault in the TCM processor. TCM P064F:00 Unauthorized Software/Calibration Detected: No Sub Type Information The TCM sets this DTC when it detects an unauthorized change in the software or calibration of the TCM. TCM P06B8:00 Internal Control Module Non-Volatile Random Access Memory (NVRAM) Error: No Sub Type Information The TCM sets this DTC when it detects an error in the nonvolatile random access memory (NVRAM).

- B1 CHECK FOR DIAGNOSTIC TROUBLE CODES (DTCS)
- Using the diagnostic scan tool, retrieve all diagnostic trouble codes (DTCs) from the TCM.
Are diagnostic trouble codes (DTCs) P0882 and/or P0883 present in the TCM?
Yes RESOLVE those diagnostic trouble codes (DTCs) first. REFER to the Diagnostic Trouble Code (DTC) Chart . No GO to B2 - B2 PROGRAM THE TCM (TRANSMISSION CONTROL MODULE) WITH THE LATEST CALIBRATION
- Ignition ON.
- Using a diagnostic scan tool, reprogram the TCM with the latest calibration. REFER to: MODULE PROGRAMMING .
- Using a diagnostic scan tool, carry out the Transmission Characterization/Solenoid IDN (identification number) routine.
- Start the engine.
- Let the engine idle for 1 minute.
- Using a diagnostic scan tool, carry out the TCM self-test.
Did the DTC return?
Yes INSTALL a new TCM. REFER to: Transmission Control Module (TCM) No The fault is not present at this time. It may have been caused by a module programming error.
