Diagnostic Trouble Code (DTC) Information

Diagnostic trouble code (DTC) information TCM-P073200

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 differs by more than 20 %.
The control module's test for the diagnostic trouble code (DTC) starts in the event of:
- Driving with gear 2.

Hint: Continuous gear when driving in TIP.

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, B5254T5, TF-80SC Emergency Mode In Case of Malfunction

Possible source
- Contact resistance or one of the solenoids controlling in an incorrect manner.
- Circuit for the solenoid: SLC1, SLB1.
- Mechanical fault in the transmission. Worn components in the transmission causing slippage or too low line pressure.

Fault symptom[s]
- Warning lights and chimes/Malfunction Indicator Light ("Check engine" light) indication/no indication
- Text window and warning symbol/Red symbol and text message
- Automatic transmission/No automatic gearshift
- Automatic transmission/No manual gear shift
- Automatic transmission/Shifts rough or jerky/Unsure when/at all times
- Automatic transmission/Gear changes take too long to complete/Unsure when/at all times
- Automatic transmission/Lockup does not work
- Driving/Poor performance/lacks power
