Visual Inspection and Pre-checks

  • If the selection is available on the scan tool (Body>Security>PATS Functions), make sure the passive entry/passive start feature is enabled. If disabled, the vehicle only starts with the key in the backup starting location.
A1 CHECK FOR BCM (BODY CONTROL MODULE) ANTENNA DIAGNOSTIC TROUBLE CODES (DTCS)
  • Ignition ON.
  • Using a diagnostic scan tool, carry out the BCM self-test. Record the DTC.

Is DTC B10C7:01, B10C9:01, B1336:01 or B1337:01 present?
Yes GO to A8
No GO to A2

A2 CHECK IF THE PASSIVE KEYS START THE VEHICLE FROM THE BACKUP STARTING LOCATION
  • Place the suspect passive key in the backup starting location and attempt to start the vehicle.
    REFER to: Passive Anti-Theft System (PATS) - System Operation and Component Description (419-01B Passive Anti-Theft System (PATS), Description and Operation).

Does the key start the vehicle?
Yes GO to A5
No GO to A3

A3 DOCUMENT THE KEY IDENTIFICATIONS USING THE BCM (BODY CONTROL MODULE) KEY ID AND RTM (RADIO TRANSCEIVER MODULE) KEY ID PARAMETER IDENTIFICATIONS (PIDS)
  • Using the diagnostic scan tool, view the BCM PIDs.
  • Using the diagnostic scan tool, monitor the following BCM PIDs:
    • TIC_01_BCM (Programmed Transmitter ID Code (TIC) Value 1)
    • TIC_02_BCM (Programmed Transmitter ID Code (TIC) Value 2)
    • TIC_03_BCM (Programmed Transmitter ID Code (TIC) Value 3)
    • TIC_04_BCM (Programmed Transmitter ID Code (TIC) Value 4)
  • Document each programmed TIC ID.
  • Using the diagnostic scan tool, view the RTM PIDs.
  • Using the diagnostic scan tool, monitor the RTM Lst_Xm_ID_Cd (Last Received Transmitter ID Code (TIC)) PID while pressing the lock and unlock buttons on the suspect key.
