Checking diagnostic trouble codes (DTCs)




Check if the fault is permanent or intermittent.
If the malfunction is intermittent, it means that the malfunction has been registered at an earlier time but the malfunction no longer remains. Intermittent faults can occur for a number of different reasons. The fault is evaluated depending on how it occurs.
Click on the VCT2000 symbol to read off the diagnostic trouble codes (DTCs).





Is the fault intermittent?

Yes - VERIFIED

No - Checking the signal cable

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

Verification

Hint: After carrying out the repair, check that the fault has been remedied.

- Ignition off.
- Reinstall the connectors, components etc.
- Ignition on.
After replacement of the power seat module, left (PSL), the seat must be initiated. See vehicle communication.
Check that the seat cannot be moved as far forward when the backrest is folded down as when it is upright.

Can the seat be operated?

Yes - FAULT FOUND

No - Fault-tracing information

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

Fault-tracing information
The fault must be diagnosed and remedied. As this is not the case, the fault-tracing has failed.
Exit fault-tracing or try again.

Do you want to exit fault-tracing?

Yes - No Fault Found

Checking the signal cable




- Check the cables between power seat module, left (PSL) terminals #B9 (#A51), #B10 (#A52) and the backrest Hall sensor for open circuit and short circuit.
Replace the signal cable if a fault is found.
If no malfunctions were detected when checking the signal cable, try changing hall sensor.
