Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information

Condition
The transmission control module (TCM) receives a signal about input and output speed from the transmission's two speed sensors. There is a determined ratio for each gear and the signals help calculate the transmission control module (TCM) gear ratio.
The diagnostic trouble code (DTC) is stored if the control module detects that:
- Gear ratio for the gear selected by the control module is close to (4%) another gear's ratio.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Oil temperature above -20°C.
- During take off.

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
- Auxiliary program Emergency mode 2 in the transmission control module (TCM) has started.

Hint: Emergency mode in case of malfunction, B6304T4, TF-80SC AWD, B6324S5, TF-80SC AWD, B6324S5, TF-80SC, B6324S4, TF-80SC AWD, B6324S4, TF-80SC Emergency Mode In Case Of Malfunction
