Start Inhibition

The start inhibition system is a comprehensive function of the security system. The start inhibition system compiles a number of parameters from the various security functions in the vehicle and then determines whether a start attempt is permitted. The checks that are run are:

• Checking depressed pedals.
  • The clutch pedal must be depressed on vehicles with manual transmissions.
  • The brake pedal must be depressed on vehicles with automatic transmissions.
• Checking the position of the gear selector. On cars with automatic transmissions, the gear selector must be in position P (park) or N (neutral).
• Checking the immobilizer. All checks run by the immobilizer must be OK.
• Checking the steering column lock. The steering column lock must be unlocked.

The function for start inhibition is checked by the engine control module (ECM). This function is based entirely on signals on the controller area network (CAN). For further information about the start process, see appropriate Design and Function information for the engine control module (ECM).
