Pinpoint Test

NOTE: The IA feature is a programmable parameter and can be enabled/disabled with a scan tool. If the feature is disabled, the IA feature to enter the vehicle and passive starting will be inoperative. To start the vehicle, the IA key has to be placed in the backup slot.
  1. CHECK THE RKE OPERATION
    1. Press the unlock button on an IA key.

    Does the driver door unlock? 

  2. CHECK THE DOOR LOCK OPERATION
    1. Lock and unlock the doors using a door lock control switch.

    Do the doors lock and unlock? 

  3. CHECK THE IA KEY
    1. Place the IA key on the center console and start the engine.

    Does the engine start? 

    • Yes: GO to 4  .
    • No: REFER to DIAGNOSTIC ROUTINE E : The Engine Does Not Start or Unable To Turn Ignition On.
  4. CHECK THE IA LOCK AND UNLOCK CAPACITIVE SENSOR PIDs 
    1. Using a scan tool, view RFA module PIDs  .
    2. NOTE: When monitoring the capacitive sensor PIDs  , it is best to select a graph view. When a sensor is touched, the PID state rapidly switches between ON and OFF for approximately 2 seconds.

      Touch both the lock and unlock sensors on the suspect exterior door handle while monitoring the RFA module PIDs  LF_HNDL_LK, LF_HNDL_UNLK, RF_HNDL_LK, and RF_HNDL_UNLK.
