    • Ignition ON.

    • Using a diagnostic scan tool, MONITOR the following PIDs:

      • P button, SBW_PRK_SW_1, SBW_PRK_SW_2, SBW_PRK_SW_3
      • R button, SBW_REV_SW_1, SBW_REV_SW_2, SBW_REV_SW_3

      • BTSI override switch: SBW_OVR_SW_1, SBW_OVR_SW_2.

    Do any of the switch PID readings indicate that any of the gear shift buttons or the BTSI overide switch is pressed? 

    Yes  If any of the gear shift buttons, PIDs P, R, N, D, S, indicate their button is pressed, GO to  P6If the BTSI override switch PID indicates one or both switches are pressed, GO to  P4

    • Repair:

      • corrosion (install new connector or terminals - clean module pins)
      • damaged or bent pins - install new terminals/pins
      • pushed-out pins - install new pins as necessary

    • Reconnect the GSM connectors. Make sure they seat and latch correctly.

    • Operate the system and verify the concern is still present

    Is the concern still present?
