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.

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. WARNING:

    Always ensure the Battery Maintenance Mode is inactive before disconnecting the low voltage 12 volt battery (or batteries). This mode can be active with the ignition off, regardless of whether the vehicle charging cord is plugged in or not. When this mode is active, the on-board high voltage battery charger(s) will energize the 12 volt battery cables and charge the 12 volt battery (or batteries). Disconnecting any battery cables while this mode is active may result in an electrical shock or a burn from hot battery cable leads.

  2. Check the 12 V battery voltage with a digital multimeter before disconnecting any battery cables leads. If the voltage is 13.5 V or above, the Battery Maintenance Mode is active. The technician must wait for the T18 Battery Charger to deactivate before disconnecting the battery negative cable. For more information, refer to Charging System Description and Operation . With Battery Maintenance Mode inactive, perform a 12 V battery disconnect by disconnecting the battery negative cable for a minimum of 10 min. Refer to Battery Negative Cable Disconnection and Connection .
  3. Reconnect the 12 V battery.
  4. Close down the current session of Techline Connect and reopen a new session.
  5. Verify the programming tool is equipped with the latest software and is securely connected to the data link connector.
  6. Access the Service Programming System (SPS) and follow the on-screen instructions for the K16 Battery Energy Control Module.
  7. Verify the K16 Battery Energy Control Module can be programmed.
    • If the K16 Battery Energy Control Module can not be programmed 
    1. Vehicle in Service Mode for 1 min.
    2. Vehicle OFF.
    3. Access SPS and follow the on-screen instructions for the K16 Battery Energy 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 K16 Battery Energy Control Module can be programmed.
      • If the K16 Battery Energy Control Module can not be programmed, replace the K16 Battery Energy Control Module.
      • Go to next step: If the K16 Battery Energy Control Module can be programmed, complete programming.
    5. Clear DTCs.
    • Go to next step: If the K16 Battery Energy Control Module can be programmed 
  8. Complete Programming and Clear DTCs.
