Faulty Signal. Intermittent Fault

Faulty signal. Intermittent fault

Checking connectors and wiring








- Check control module connector C for an intermittent short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
- Connect the control module.
- Check the function of the micro-switches.
- Check that the micro-switches appear normal.
- Ignition on.
- Read off the status of the micro-switches.
- Activate the right micro-switch manually so that it is constantly active.
- Operate the left micro-switch manually.
The status should change from activation (micro-switch on) to non activation (micro-switch off).
Activate the left micro-switch manually so that it is constantly active.
Operate the right micro switch manually.
The status should change from activation (micro-switch on) to non activation (micro-switch off).

Other information:
- To access / replace the control module see Replacing the control module Service and Repair.
- To access the micro-switch for the cover lock, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches.
- There is a short-circuit if the status is low when the micro-switch is inactive.
- There is an open-circuit or a short-circuit to supply voltage if the status is high when the micro switch is activated.

Hint: The micro-switch can be activated by hand or using a pointed tool. Be careful.









Does the status change?

Yes - DONE

- Ignition off.
Check the connectors for the micro-switches for an intermittent short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Connect an ohmmeter between micro switch connector 1 and ground and between 2 and ground. Check for an intermittent short-circuit to ground according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Try a new micro-switch if a short-circuit is found.
If no fault is found there is probably a fault in the cable between the control module and the micro-switch connector.
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).
