K160 Brake System Control Module: Programming and Setup

Note:

  • Always verify the module has the newest software available before replacing the module.
  • 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 a battery maintainer or power supply that provides a steady and stable voltage. Do not use a battery charger, as charging voltage will often fluctuate when connected to the vehicle. This may interrupt programing. If a battery maintainer is not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply.
  • 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 or an existing control module, perform the following procedure:

  1. Access the Service Programming System (SPS) and follow the on-screen instructions.
  2. If equipped with Brake Pad Life Monitor (JBP), on the SPS Supported Controllers screen, select K160 Brake System Control Module - Prepare Module for Removal and follow the on-screen instructions.

  4. On the SPS Supported Controllers screen, select K160 Brake System Control Module - Setup and follow the on-screen instructions.
  5. If the A104 Brake Master Cylinder was also replaced proceed to step 7.
  6. If only the K160 Brake System Control Module was replaced proceed to step 10.
  7. Perform the scan tool Control Functions, Brake Pressure Sensor Calibration.
  8. Perform the scan tool Control Functions, Brake System Plunger Pressure Rise Starting Point Learn.
  9. Perform the scan tool Control Functions, Brake System Plunger Motor Position Sensor Learn.
  10. Perform the scan tool Control Functions, Brake Hydraulics Test procedure.
  11. If the Brake Hydraulics Test fails perform the scan tool Control Functions, Automated Brake Bleed procedure
  12. If the programming procedure did not complete and a Device Control Limits Exceeded message is displayed refer to Device Control Limits Exceeded Error
  13. Clear DTCs.
  14. If ABS, Traction Control and/or Stabilitrak indicators or Brake Related Messages are ON after performing programming and setup, do the following:
    1. Disconnect the scan tool from the X84 Data Link Connector.
    2. Ignition/Vehicle 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 10 min to power down.
    3. Ignition ON/Vehicle In Service Mode, verify ABS, Traction Control and/or Stabilitrak indicators or Brake Messsages are Off. If not, repeat the above step to make sure the vehicle is in sleep mode.
    4. Clear DTCs.

Reprogram Control Module

To reprogram an existing control module, perform the following procedure:

  1. Access the Service Programming System (SPS) and follow the on-screen instructions.
  2. On the SPS Supported Controllers screen, select K160 Brake System Control Module - Programming and follow the on-screen instructions.
  3. If the programming procedure did not complete and a Device Control Limits Exceeded message is displayed refer to Device Control Limits Exceeded Error
  4. Clear DTCs.
  5. If ABS, Traction Control and/or Stabilitrak indicators or Brake Related Messages are ON after performing programming, do the following:
    1. Disconnect the scan tool from the X84 Data Link Connector.
    2. Ignition/Vehicle 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 10 min to power down.
    3. Ignition ON/Vehicle In Service Mode, verify ABS, Traction Control and/or Stabilitrak indicators or Brake Messsages are Off. If not, repeat the above step to make sure the vehicle is in sleep mode.
    4. Clear DTCs.

Unsuccessful Programming Recovery

Note:

  • Ensure the EL-52100 (MDI 2) is used when programming the vehicle. Using the EL-47955 (MDI) will result in a programming failure.
  • It may be necessary to use another EL-52100 (MDI 2) and/or cables to verify proper operation to eliminate the possibility of faulty equipment.
  • If Ethernet programming fails, ensure there is no fault in the Ethernet circuits between the X84 Data Link Connector and K56 Serial Data Gateway Module. Refer to Scan Tool Does Not Communicate with Vehicle to diagnose these Ethernet circuits.

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

  1. Exit Service Programming System (SPS) and disconnect all programming equipment from the vehicle.
  2. Disconnect all battery voltage or ignition voltage sources from the control module.

    3. Note: All voltage sources must be removed for a minimum of 10 min. This can be done several ways and should be completed by using the least intrusive way. This can vary depending on vehicle and control module location and can be done by one of the options listed below:

    • Removing all fuses supplying battery voltage and ignition voltage to the control module.
    • Disconnecting all harness connectors from the control module.
    • Performing a 12 V battery disconnect by disconnecting the battery negative cable. Refer to Battery Negative Cable Disconnection and Connection.

  3. Reconnect all battery voltage and ignition voltage sources to the control module.
  4. Close down the current session of Techline Connect and reopen a new session.
  5. Verify the control module, data link connector, and programming tool connections are secure and the tool software is up to date.
  6. Ignition/Vehicle OFF, ensure that the key fob is inside the vehicle and not moved for the duration of the programming to prevent an inadvertent power mode change during programming.
  7. Access the Service Programming System (SPS) and follow the on-screen instructions for the control module.
  8. Verify the control module can be programmed.
    • If the control module can not be programmed
    1. Ignition ON/Vehicle in Service Mode for 1 min.
    2. Ignition/Vehicle OFF.
    3. Access SPS and follow the on-screen instructions for the control module.

      4. Note: If programming is still not successful after the second programming attempt, check the following:

      • For facilities using an internet firewall, ensure firewall settings are not blocking file downloads and/or require elevated rights.
      • For United States and Canada GM dealers, the appropriate firewall settings can be found in the GM DEALER INFRASTRUCTURE & SECURITY GUIDELINES (DISG) section 2.d.vii.

    4. Verify the control module can be programmed.
      • If the control module can not be programmed, replace the control module.
      • If the control module can be programmed
    5. Clear DTCs.
    • If the control module can be programmed
  9. Clear DTCs.
