Signal Too High

Signal too high

Status check
Check if the outside temperature gauge display is outside its permitted range.

Does the outside temperature gauge display a value outside its permitted range?

Yes - Checking components and wiring

No - Checking components and wiring

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

Checking components and wiring

Hint: If the cable and the combined instrument panel are fault free the voltage between terminals #1 and #2 on the outside temperature sensor connector must be approximately 5 V.

Check the connector for the outside temperature sensor. Check for contact resistance and oxidation.
Check the signal cable between combined instrument panel terminal #A19 (#49) and outside temperature sensor terminal #1. Check for a short-circuit to supply voltage. Check for an open-circuit.
Check the signal cable between combined instrument panel terminal #A12 (#42) and outside temperature sensor terminal #2. Check for a short-circuit to supply voltage. Check for an open-circuit.
Remedy as necessary.

Verification

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




- Ignition off.
- Reinstall the connectors, components etc.
Check that the outside temperature sensor display is within its permitted range.

Does the outside temperature sensor display values within their permitted range?

Yes - VERIFIED

No - VERIFICATION FAILED

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

Hint: If the cable and the combined instrument panel are fault free the voltage between terminals #1 and #2 on the outside temperature sensor connector must be approximately 5 V.

Check the connector for the outside temperature sensor. Check for contact resistance and oxidation.
Check the signal cable between combined instrument panel terminal #A19 (#49) and outside temperature sensor terminal #1. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.
Check the ground cable between combined instrument panel terminal #A12 (#42) and outside temperature sensor terminal #2. Check for an intermittent short-circuit to supply voltage. Check for an intermittent open-circuit.

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).
