Removal Procedure

    Object Number: 538817 Size: SH

    Notice: To prevent possible electrostatic discharge damage to the BCM, do not touch the connector pins or soldered components on the circuit board.

    Notice: To prevent internal BCM damage, the ignition must be OFF when disconnecting or reconnecting power to BCM (for example, battery cable, BCM connectors, BCM fuses, jumper cables, etc.).

    Notice: The BCM electrical connectors are designed with tabs and slots that allow the connectors to only fit one way. The connectors do not require excessive force if being installed correctly. Installing the connectors with the wrong mating half or upside down can cause damage to the connector, the BCM, or other vehicle components or systems.

  1. Turn OFF the ignition switch.
  2. Remove the front floor kick-up panel (RH). Refer to Front Floor Kick-Up Panel Replacement in Interior Trim.
  3. Pull up on the BCMs lower mounting tab to release the BCM from the bracket.
  4. Release the BCMs upper mounting tabs by lifting the BCM out of the slots in the bracket.
  5. Disconnect the harness connectors from the BCM.
  6. Remove the BCM from the vehicle.
