Signal Too High







Signal too high

Checking for permanent or intermittent faults




- Ignition on.
Check the outside temperature.

Note! The outside temperature sensor is always located in the right door mirror, irrespective of whether the car is left or right-hand drive.





Is the temperature within its permitted range?

Yes - Intermittent fault

No - Checking for a short-circuit

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

Checking for a short-circuit

If the car is equipped with a 16-pin connector
Check the cable between driver door module (DDM) terminal #18A and power door mirror connector terminal #3. Check for an open-circuit.
Check the cable between driver door module (DDM) terminal #14A and power door mirror connector terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.
Replace the cable if a fault is found.
Try a new outside temperature sensor if no fault was found.

Continue - Verification

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

Intermittent fault
Check the control module and power door mirror connectors. Check for contact resistance, oxidation and loose connections.

If the car is equipped with a 16-pin connector
Check the cable between driver door module (DDM) terminal #14A and power door mirror terminal #2. Check the cable between control module terminal #18A and power door mirror terminal #3. Check these cables for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
Try a new outside temperature sensor if no fault was found.

Verification

Hint: After carrying out the repair, check that the fault has been remedied.








- Ignition off
- Reconnect the components, connectors etc.
- Ignition on.
Check the outside temperature.





Is the temperature within its permitted range?

Yes - VERIFIED

No - VERIFICATION FAILED

Fault-tracing information





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?

Yes - Exit fault-tracing

No - Attempt New Test

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

Attempt New Test - Checking for permanent or intermittent faults

FAULT-TRACING FAILED - No Fault Found

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).
