Signal Too High. Intermittent Fault

Signal too high. Intermittent fault

Checking the signal cable








- Ignition off.
- Disconnect the connector from the central electronic module (CEM).

Hint: The signal line goes from the Central electronic module (CEM) to ground via glass breakage circuit left, glass breakage circuit right and glass breakage circuit tailgate.

Check the signal cable. Check for a short-circuit to supply voltage.
Begin by measuring at the grounding point and then go backward along the circuit to find the defect.
Remedy as necessary.

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).
