Signal Missing

Signal missing

Status check
- Start the engine and allow it to idle or drive the car until it has reached operating temperature.
Check whether the engine coolant temperature (ECT) gauge is displaying a value outside its permitted range.

Does the engine coolant temperature (ECT) gauge display a value outside its permitted range?

Yes - Checking components and wiring

No - Checking components and wiring

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

Checking components and wiring
Check the signal cable between combined instrument panel terminal #B10 and the engine control module (ECM). Check for a short-circuit to supply voltage according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault. Check for a short-circuit to ground according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault. Check for an open-circuit according to Checking wiring and terminals. Permanent fault Checking Wiring And Terminals. Permanent Fault.
Remedy as necessary.

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




- Ignition off.
- Reinstall the connectors, components etc.
- Start the engine and allow it to idle or drive the car until it has reached operating temperature.
Check the engine coolant temperature (ECT) and compare with the engine coolant temperature (ECT) gauge reading in the combined instrument panel. At approximately 80°C the needle is midway between Min and Max.
