    Yes  GO to  G13.
    No  REPAIR the circuit in question

  9. G9 CHECK THE BCM KEYPAD PIDs

    • Using a diagnostic scan tool, view BCM PIDs.
    • Press each keyless entry keypad button while observing the BCM PIDs (KYPD_BTN_1/2, KYPD_BTN_3/4, KYPD_BTN_5/6, KYPD_BTN_7/8, and KYPD_BTN_9/0).

    Do the PIDs display active when the corresponding button is pressed? 

    Yes  GO to  G13.
    No  GO to  G10.

  10. G10 CHECK THE KEYLESS ENTRY KEYPAD

    • Using a diagnostic scan tool, view the BCM PIDs.

      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary
    • Reconnect all BCM connectors. Make sure they seat and latch correctly.
    • Operate the system and determine if the concern is still present.

    Is the concern still present? 

    Yes  CHECK OASIS for any applicable TSBs. If a TSB exists for this concern, DISCONTINUE this test and FOLLOW TSB instructions. If no TSBs address this concern, INSTALL a new BCM. REFER to Multifunction Electronic Modules .
    No  The system is operating correctly at this time. The concern may have been caused by module connections. ADDRESS the root cause of any connector or pin issues.
