Checking the component




- Ignition off.
Check the micro-switch connector. Check for a short-circuit to ground. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Connect an ohmmeter between micro-switch connector terminal #1 and ground and terminal #2 and ground. The micro-switch must be in the unaffected position.
Check for a short-circuit to ground. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
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.

Other information:
- To access the micro-switch for the front locking arm, rear position, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches
- The micro-switch can be activated by hand or using a pointed tool. Be careful.









Does the micro-switch function?

Yes - Verification

No - Checking the connectors

-------------------------------------------------

Checking the connectors
Check control module connector C. Check for a short-circuit to ground. See Checking wiring and terminals. Permanent fault Checking Wiring and Terminals. Permanent Fault.
Remedy as necessary.

- To connect the breakout box, see Connecting the convertible control unit breakout box Connecting the Breakout Box
- To access and replace the control module see Replacing the control module Service and Repair.









Was a fault detected?

Yes - Verification

No - Checking the wiring

-------------------------------------------------

Checking the wiring








- Check the function of the micro-switch
- Check that the switch appears normal
- Ignition on
- Operate the micro-switch manually
- Read off the status of the micro-switch.
The status should change from activation (micro-switch on) to non activation (micro-switch off).

Other information:
- For the location of the components, see Convertible system Component Locations
- For other values, see Opening and closing the convertible top Opening and Closing the Convertible Top
- To access or replace the micro-switch for the front latch, 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
- There is an open-circuit or a short-circuit to voltage if the status is constantly high.

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





Does the status change?

Yes - Verification

No - Fault-tracing information

Fault-tracing information
The fault should have been detected and remedied. As this is not the case fault-tracing has failed.
Exit fault-tracing for this diagnostic trouble code (DTC) or make another attempt.

Do you want to exit fault-tracing?
