Passive Start Backup

When the vehicle is unlocked with the emergency key or the vehicle does not detect a smart key. It is then necessary to use the passive start backup procedure for the following:

To disarm the alarm.
Start the engine.

The following passive start backup process must be followed in this event:

Press the ignition switch if the Remote Function Actuator (RFA) fails to locate the smart key. 'Smart Key Not Recognized - Reposition Or Place As Shown And Press Start Button' appears in the Instrument Cluster (IC) message center.
For vehicles with a manual steering column position the smart key against the lower left of the steering column, with the switches facing downward. The ridges denote actual location of the Immobilizer Antenna Unit (IAU).
For vehicles with a column for power steering position the smart key to the left of the steering column cowl panel. The switches on the smart key must face outwards.
Press the ignition switch with the brake pedal pressed to start the engine.

NOTE: If the 'Smart Key Not Recognized - Reposition Or Place As Shown And Press Start Button' message is no longer displayed (only displayed for 10 seconds), then the sequence would have to be repeated.

This process bypasses the data exchange between the RFA and the Body Control Module/Gateway Module (BCM/GWM). This is an inductive process and operates even if the battery in the smart key is discharged. A transponder within the smart key is detected by the IAU. The IAU communicates this code with the BCM/GWM through a Local Interconnect Network (LIN) connection. The BCM/GWM then initiates the vehicle start process in the normal manner.
