Checking The Ignition Switch

Check that the ignition lock or key does not have any mechanical faults that can prevent starts.

• Insert the key and check that it locks properly.
• Remove the key and check that it does not jam or stick. If the message is not correctly received try with another key. If this also jams, slacken off and pull out the securing bolts on the Start control module (SCU).

If mechanical problems persist, replace the Start control module (SCU).
