Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-P062F00

Condition
The Transmission control module (TCM) has three different internal memories, one for the program application (FLASH), one for permanent storage of information (EEPROM) and one for current information (RAM).
With the ignition off, certain information is saved from RAM to EEPROM and then the information is erased from RAM.
The information that is stored includes diagnostic trouble codes (DTCs) and accompanying data, adaptation values, etc.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Data storage to the control module's EEPROM memory is not correctly carried out.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Ignition on.

Note! The control module can only detect the fault once the test has been started and the diagnostic trouble code (DTC) is stored when the conditions are met.





Substitute value
- The transmission control module (TCM) takes a basic value for adaptation.
- Any stored diagnostic trouble codes (DTCs) can disappear.

Possible source
- Internal fault in the transmission control module (TCM).

Fault symptom[s]
- Vibration and jerking when shifting
