Current Too High. Intermittent Fault






Current too high. Intermittent fault

Mechanical check
Carry out the mechanical check according to Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches.

Was the fault found?

Yes - Fault-tracing information

No - Checking the connectors

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

Checking the connectors
- Check control module connector C. Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for contact resistance and oxidation according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Remedy as necessary.

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









Was the fault found?

Yes - Fault-tracing information

No - Checking connectors and wiring

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

Checking connectors and wiring




- Check that the micro-switch for the front locking arm, front position 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).
Remedy as necessary.

Other information:
- To access or replace the micro-switch for the front locking arm, front position, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches
- There is a short-circuit to ground if the status is low when the switch inactive
- If the status is high with the micro switch activated there is an open-circuit or a short-circuit to supply voltage.

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 components and wiring

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

Checking components and wiring




- Check the micro-switch connector. Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults. Check for contact resistance and oxidation Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults
- Ignition on.
The micro-switch should be in unaffected position.
Connect a voltmeter between micro-switch terminal #1 and ground.
Check for an intermittent short-circuit to supply voltage according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Connect a voltmeter between micro-switch terminal #2 and ground.
Take readings as above.
Replace the micro-switch if a short-circuit is found.
Remedy as necessary.

Other information:
- To access or replace the micro-switch for the front locking arm, front position, see Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches
- For other values, see Opening and closing the convertible top Opening and Closing the Convertible Top
- To connect the breakout box, see Connecting the convertible control unit breakout box Connecting the Breakout Box
- To access or replace the control module, see Replacing the control module Service and Repair.









Was a short-circuit found?

Yes - Fault-tracing information

No - Checking components and wiring

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

Checking components and wiring




- Ignition off.
Connect an ohmmeter between micro-switch terminals #1 and #2. Check for an intermittent open-circuit according to Checking wiring and terminals. Intermittent faults Checking Wiring and Terminals. Intermittent Faults.
Activate the micro-switch manually.
If an open-circuit is found, replace the micro-switch according to Replacing and adjusting micro-switches Replacing and Adjusting Micro-Switches.
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.









Was the fault found?

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 - Mechanical check
