Service procedures

This routine can be used to reset the drive unit immobilizer to the virgin state. This unlearns the code that pairs a drive unit to the security controller. This routine needs to be performed when either the security controller is replaced or the drive unit is permanently removed from a vehicle. Immobilizer reset takes 15 minutes. During this time, DI_immobilizerState will be in RESET, and at the end of the procedure it will become DISARMED. Drive rail must remain on throughout the entire procedure. When the immobilizer reads "Disarmed", the drive unit can be paired with the security controller the next time it is powered on.
