  1. A new body control module (BCM) must be programmed with the proper RPO configurations. The BCM stores the information regarding the vehicle options and if the BCM is not properly configured with the correct RPO codes, the BCM will not control all of the features properly. The Tech 2 software will automatically prompt you with the RPO's available for the vehicle. Ensure that the following conditions exist in order to prepare for BCM programming:
    2. • The battery is fully charged.
    • The ignition switch is in the ON position.
    • The data link connector (DLC) is accessible.
    • All disconnected modules and devices are reconnected before programming.
  2. To setup a new BCM, access the SPECIAL FUNCTIONS menu on the scan tool to program the BCM. Select SETUP NEW BCM and follow the instructions on the scan tool.
  3. If the BCM fails to accept the program, perform the following steps:
    4. • Inspect all BCM connections.
    • Verify that the scan tool has the latest software version.

BPP Sensor Calibration

Important: If the BCM, electronic brake control module (EBCM) or the brake apply sensor (BAS) is replaced a brake pedal position (BPP) sensor calibration must be preformed.

Perform the BPP Sensor Calibration using a scan tool if the BCM, EBCM or the brake apply sensing system (BASS) sensor has been replaced.

Using a scan tool preform the following:

  1. Navigate to Body.
  2. Navigate to the Body Control Module menu.
  3. Enter Special Functions.
  4. Select BPP Sensor Calibration.
  5. Follow the on-screen directions.

Passkey 3 Programming Procedures

Important:  If any module or device listed is replaced, programming of the module must be done prior to performing the Passkey 3 Programming procedure.

Perform the Passkey 3 Programming Procedure if any of the following components have been replaced:

    • The BCM
    • The powertrain control module (PCM)
        Refer to Service Programming System (SPS) in Programming and Setup for the proper procedure.

Important: After programming, perform the following to avoid future misdiagnosis:

  1. Turn the ignition OFF for 10 seconds.
  2. Connect the scan tool to the data link connector.
  3. Turn the ignition ON with the engine OFF.
  4. Use the scan tool in order to retrieve history DTCs from all modules.
  5. Clear all history DTCs.
