Faulty Signal. Intermittent Fault

Faulty signal. Intermittent fault

Checking components








- Check the function of the micro-switch
- Check that the switch appears normal
- Ignition on
- Read off the status of the micro-switch
- Operate the micro-switch manually.
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 the micro-switch for the tensioner rib, 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 - Fault-tracing information

No - Checking the connector

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

Checking the connector
Check control module connector C. Check for an intermittent short-circuit to ground. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

Other information:
- To access or replace the control module see Replacing the control module Service and Repair.









Was a fault detected?

Yes - Fault-tracing information

No - Checking the wiring

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

Checking the wiring




- Ignition off.
Check the micro-switch connector. Check for an intermittent short-circuit to ground. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Connect an ohmmeter between micro-switch terminal #1 and ground and between terminal #2 and ground. Take readings for an intermittent short-circuit to ground. See Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
The switch should be in unaffected position.
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.

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









Was a fault detected?

Yes - Fault-tracing information

No - No Fault Found

Fault-tracing information




Information

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).

Do you want to view the information again?

Yes - Attempt New Test

No - FAULT FOUND

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

FAULT-TRACING FAILED - DONE

Attempt New Test - Checking components
