Current too high. Permanent fault
Mechanical check
Carry out mechanical check according to: Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches
Was the fault found?
Yes - Verification
No - Checking connectors and wiring
-------------------------------------------------
Checking connectors and wiring
- Check control module connector D. Check for a short-circuit to supply voltage. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Ignition on.
Connect a voltmeter between control module terminal #D1 and ground, front lock.
Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Read off the program status of the convertible top. Check the values at the relevant step.
Remedy as necessary.

Was a short-circuit found?
Yes - Verification
No - Checking the component
-------------------------------------------------
Checking the component
- Check the relevant motor connector 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 motor terminal #1 and ground.

Remedy as necessary.
Other information:
- To access or replace the motor for the front lock, see Replacing motors Service and Repair.
Was a short-circuit found?
Yes - Verification
No - Checking the cable
-------------------------------------------------
Checking the cable
- Check that the micro-switch appears normal
- Ignition on
- Read off the status of the micro-switch for the front locking arm, rear position
- Operate the micro-switch manually.
The status should change from activation (micro-switch on) to non activation (micro-switch off).
Other information:
- 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 the component
-------------------------------------------------
Checking the component
- Check control module connector C. Check for a short-circuit to supply voltage. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Ignition on.
Connect a voltmeter between micro-switch terminal #1 and ground.
Activate the micro-switch manually so that it is active throughout the test

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 the micro-switch connector. Check for contact resistance and oxidation. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault
- Ignition off.
Connect an ohmmeter between micro-switch terminals #3 and #4.
Activate the micro-switch manually so that it is active throughout the test.
Test 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 micro-switch for the front locking arm, 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.
