Signal Too High






Signal too high

Checking the position of the gear selector

Hint: The gear position and torque limiting use a common cable. The circuit can be checked by checking the gear selector signal to the engine control module (ECM).




- Ignition on.
- Go into scrolling values for engine control module (ECM) Fenix 5.1.
Read off the gear selector position.
Move the gear selector to all gear positions several times. Check that the gear selector position reads P/N when the gear selector is in the P/N position and R/D/3/L when the gear selector is in the R/D/3/L positions.





Are these readings OK?

Yes - Intermittent fault

No - Checking for a short-circuit

-------------------------------------------------

Checking for a short-circuit
Check the cable between transmission control module (TCM) terminal 11 and engine control module (ECM) terminal 7 for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.

Verification

Hint: After repairs have been completed they must be verified as follows to ensure that the fault has been eliminated:








- Ignition off.
- Reconnect the connectors, reinstall components etc.
- Ignition on.
- Go into scrolling values for engine control module (ECM) Fenix 5.1.
Read off the gear selector position.
Move the gear selector to all gear positions several times. Check that the gear selector position reads P/N when the gear selector is in the P/N position and R/D/3/L when the gear selector is in the R/D/3/L positions.





Are these values OK?

Yes - VERIFIED

No - VERIFICATION FAILED

Fault-tracing information




Information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?

Yes - Exit fault-tracing

No - Attempt New Test

Intermittent fault





Intermittent fault

Intermittent fault
Check the cable between automatic transmission control module (TCM) terminal 11 and engine control module (ECM) terminal 7 for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring And Terminals. Intermittent Faults.

Information

Fault-tracing information
If the fault is intermittent, do not verify fault-tracing if the fault does not recur.
It is possible to view the information again, or leave fault-tracing for this diagnostic trouble code (DTC).
