Checking Connectors

Checking Connectors







Check that the connector terminals for the electronic throttle module are OK. Check that there is voltage to the throttle unit from the system relay. With ignition on there should be a cheeping noise from the throttle unit for a moment, when it receives voltage.

Check that the battery voltage is normal. Check that the charging status of the battery is OK.

Symptom check
In certain specific cases, to determine if the fault is permanent or intermittent, the engine must be started and stopped up to three times (to force the fault to occur). Cancel when the symptoms appear in the car but keep the engine running.

HINT: Check for symptoms between each start of the engine. See the fault code information. The symptom "accelerator pedal (AP) is ignored when braking" can be used as a check. In the event of faults, it is not possible to increase the engine speed (RPM) at the same time as the brake pedal is depressed.

NOTE: The voltage supply to the electronic throttle module must be interrupted to empty the memory between each start.

HINT: Interrupt the supply voltage to the electronic throttle module by removing the affected fuse (do not forget to reinstall the fuse before the next engine start). See the fuses In the integrated relay/fuse box in the engine compartment.

Read off diagnostic trouble codes (DTCs) with the engine running.

Is only diagnostic trouble code (DTC) ECM-917F stored?

YES: Continue with Test.
NO: Go to Fault-Tracing Information. Fault-Tracing Information
