Was a short-circuit found?
Yes - Verification
No - Checking wiring
-------------------------------------------------
Checking wiring
- Check that the micro-switch appears normal.
- Ignition on.
- Read off status for the front locking arm micro-switch, rear position.
- Operate the micro-switch manually.
The status should change from activation (micro-switch on) to non activation (micro-switch off).
Other information:
- To access / replace the front locking arm micro-switch, rear position, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches.
- There is a short-circuit to ground if the status is constantly low.
- If the status is constantly high there is an open-circuit or a short-circuit to ground.
Hint: The micro-switch can be activated by hand or using a pointed tool. Be careful.
Does the status change?
Yes - Verification
No - Checking component
-------------------------------------------------
Checking component
- Check control module connector C for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
- Ignition on.
Connect a voltmeter between micro-switch 3 and ground.
Activate the micro-switch manually so that it is active throughout the test
Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Replace the micro-switch if a short-circuit is found.
Remedy as necessary.
Other information:
- To access / replace the locking arm micro-switch, rear position, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches.
Hint: The micro-switch can be activated by hand or using a pointed tool. Be careful.
Was a short-circuit found?
Yes - Verification
No - Checking for an open-circuit in the micro-switch
-------------------------------------------------
Checking for an open-circuit in the micro-switch
- Check control module connector C and micro-switch connector for contact resistance and oxidation according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
- Ignition off.
Connect an ohmmeter between micro-switch 3 and 4.
Activate the micro-switch manually so that it is active throughout the test.
Measure for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
If an open-circuit is found, replace the front locking arm micro-switch, rear position.
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.
Other information:

Hint: The micro-switch can be activated by hand or using a pointed tool. Be careful.
Select Continue when the fault has been remedied.
