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.
  • In the USA/CAN market, the clutch pedal must be pressed on vehicles with manual transmissions
  • During passive starting (cars with the keyless entry system only), the brake pedal must be pressed on vehicles with automatic transmissions or the clutch pedal on vehicles with manual 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).
