Chevrolet Sonic Repair Manual: Body Control Module Programming and Setup

Chevrolet Sonic Repair Manual / Electrical / Data and Communication Network / Body Control Module Programming and Setup

Note:

  • DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the control module is not properly configured with the correct calibration software, the control module will not control all of the vehicle features properly.
  • Ensure the programming tool is equipped with the latest software and is securely connected to the data link connector. If there is an interruption during programming, programming failure or control module damage may occur.
  • Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. When required install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
  • Turn OFF or disable systems that may put a load on the vehicles battery such as; interior lights, exterior lights (including daytime running lights), HVAC, radio, etc.
  • During the programming procedure, follow the SPS prompts for the correct ignition switch position.
  • Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Replace and Program Control Module

To program a replacement K9 Body Control Module (BCM), perform the following procedure:

  1. Install EL-49642 SPS programming support tool.
  2. Note:

    Make sure the vehicle ignition switch state is in appropriate position for the following step.

    • For Key Ignition System, begin with the ignition in the RUN position.
    • For Push Button Start System, begin with the vehicle in vehicle OFF power mode. The Service Programming System will power mode the vehicle.
  3. Access the Service Programming System (SPS) and follow the on-screen instructions.
  4. On the SPS Supported Controllers screen, select K9 Body Control Module - Programming and follow the on-screen instructions.
  5. Perform the following for the appropriate ignition type prior to proceeding with the next step:
  • Key Ignition System: Key in the ignition and any additional keys must be away from the vehicle at least 3 m.
  • Push Button Start System: Keyless entry transmitter must be in the programming pocket. Refer to the owner manual for the exact pocket location. All additional transmitters must be away from the vehicle at least 3 m.

Note:

The following programming step may take between 10–12 min and progress will appear to have stopped during this process. This is a normal security timer response and a restart should not be performed. If the DTC B389A set immediately after programming a replacement BCM, the Immobilizer Learn procedure was not properly completed. The Immobilizer Learn procedure needs to be performed again.

  • On the SPS Supported Controllers screen, select IMMO Immobilizer Learn - Setup. On the next screen, select Body Control Module IMMO Learn with Existing Transponder or Remote Key and follow the on-screen instructions. When Immobilizer Learn is complete, press the Unlock button on the keyless entry transmitter to allow the keyless entry transmitter to exit the Immobilizer Learn mode.
  • Note:

    When performing the Tire Pressure Monitor Sensor Learn during BCM setup, the EL-46079 tire pressure monitor diagnostic tool must be used to activate each tire pressure sensor for vehicles with UJM.

    • For Key Ignition System, begin with the ignition in the RUN position.
    • For Push Button Start System, begin with the vehicle in vehicle ON power mode.
  • On the SPS Supported Controllers screen, select K9 Body Control Module - Setup (or K9 Body Control Module - Configuration & Setup) and follow the on-screen instructions.
  • Check the driver information center display for additional messages regarding further calibration instructions. If there are no additional driver information center instructions present, programming is complete.
  • At the end of programming, choose the “Clear DTCs” function on the SPS screen.
  • If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the K17 Electronic Brake Control Module after performing BCM programming and setup, do the following:
    1. Disconnect the scan tool from the X84 Data Link Connector.
    2. Ignition OFF, all access doors closed, all vehicle systems OFF, and all keys at least 3 m (9.8 ft) away from the vehicle. It may take up to 2 min to power down.
    3. Ignition ON, verify DTC C0161 is in history. If not, repeat the above step to make sure the vehicle is in sleep mode.
    4. Use the scan tool to clear the DTCs.
    Reprogram Control Module

    To program an existing K9 Body Control Module, perform the following procedure:

    1. Install EL-49642 SPS programming support tool.
    2. Note:

      Make sure the vehicle ignition switch state is in appropriate position for the following step.

      • For Key Ignition System, begin with the ignition in the RUN position.
      • For Push Button Start System, begin with the vehicle in vehicle ON power mode.
    3. Access the Service Programming System (SPS) and follow the on-screen instructions.
    4. On the SPS Supported Controllers screen, select K9 Body Control Module - Programming and follow the on-screen instructions.
    5. Note:

      When performing the Tire Pressure Monitor Sensor Learn during BCM setup, the EL-46079 tire pressure monitor diagnostic tool must be used to activate each tire pressure sensor for vehicles with UJM.

    6. On the SPS Supported Controllers screen, select K9 Body Control Module - Setup (or K9 Body Control Module - Configuration & Setup) and follow the on-screen instructions.
    7. Check the driver information center display for additional messages regarding further calibration instructions. If there are no additional driver information center instructions present, programming is complete.
    8. At the end of programming, choose the “Clear DTCs” function on the SPS screen.
    9. If ABS, Traction Control and/or Stabilitrak indicators are ON and DTC C0161 is set in the K17 Electronic Brake Control Module after performing BCM programming and setup, do the following:
      1. Disconnect the scan tool from the X84 Data Link Connector.
      2. Ignition OFF, all access doors closed, all vehicle systems OFF, and all keys at least 3 m (9.8 ft) away from the vehicle. It may take up to 2 min to power down.
      3. Ignition ON, verify DTC C0161 is in history. If not, repeat the above step to make sure the vehicle is in sleep mode.
      4. Use the scan tool to clear the DTCs.
    Unsuccessful Programming Recovery

    In the event of an interrupted or unsuccessful programming event, perform the following steps:

    1. Ignition ON. Ensure the control module, DLC and programming tool connections are secure and the SPS software is up to date.
    2. Verify the control module can be reprogrammed.
    • If the control module cannot be reprogrammed
    1. Ignition OFF for one minute, ignition ON.
    2. Verify the control module can be reprogrammed.
    • If the control module cannot be reprogrammed, replace the control module.
    • If the control module can be reprogrammed.
  • All OK.
    • If the control module can be reprogrammed
  • All OK.
  • Repair Instructions

    Perform the Diagnostic Repair Verification after completing the repair.
