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 cable goes from the Central electronic module (CEM) to ground via glass breakage circuit right and glass breakage circuit left.

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).
