Fault codes generated and possible correlated faults

The engine control unit generates no fault code in the event of an engine start button fault.

No errors are indicated on the dashboard

Possible correlated faults: the starter motor cannot be operated. Check:

Note

Check integrity of electric circuit - short-circuit to vdc = with dashboard on, using a voltmeter, a voltage is measured between the wire tested and ground.

Check integrity of electric circuit - short-circuit to ground = with the battery cables disconnected, using an ohmmeter, continuity is detected between the wire tested and ground.

Check integrity of electric circuit - open circuit = with the battery cables disconnected, using an ohmmeter, no continuity is detected between the two ends of the wire tested.

The dds instrument can be used to display the activation state of the engine start button.

If none of the tests described above identifies the problem and the power supply and ground for the engine control unit are in correct working order, replace the engine control unit.

Component replacement methods

No special measures are necessary in order to replace the starter button.
