Checking Function of the Starter Motor After Start Attempts

Checking the function of the starter motor after start attempts

Checking the function of the starter motor after start attempts




- Ignition off
- Select neutral (automatic transmissions: "N"). Apply the parking brake
- Expose the starter motor relay. Remove the relay. For the location of the relays, see the wiring diagram
- Temporarily connect two cables to relay base terminals #3 (30) and #5 (87)
- The function of the starter motor must be checked by temporarily short-circuiting the cables to each other so that the control solenoid is powered and the starter motor engages.

Hint: A starter motor relay without a protective cover can be used to create the short-circuit. Closes the switches manually.

Note! Do not bridge directly in the relay base or the connections in the base may be damaged.

Break the circuit after 5 seconds. The starter motor should then stop immediately.









Did the starter motor stop immediately?

Yes - Replacing the component

No - Replacing the component

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

Replacing the component
Try a new control solenoid. If this does not help, try a new starter motor.

Hint: Check that nothing is sticking in the control solenoid, linkage or in the drive gear in the starter motor.

Remedy as necessary.

Is the function OK?

Yes - FAULT FOUND

No - 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
