Programming an Existing or New Control Module

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

    NOTE:
    • Ensure the EL-52100  (MDI 2) is used when programming the vehicle and verify it is working properly. Using the EL-47955 (MDI) will result in a programming failure.
    • Verify all control modules are connected and communicating before attempting to program the K179 Automated Driving Mapping Module.
    • Verify the key fob is inside the vehicle. If the key fob is not inside the vehicle, the serial data authentication configuration procedure which runs automatically at the end of the programming step will fail even though the programming appears to run successfully. If the serial data authentication configuration procedure fails, DTC U1962 will set and/or the setup step will fail or be incomplete.
  1. 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.
  2. Disconnect Wi-Fi dongle from MDI2. Install EL-52100  (MDI 2) using wired USB Connection from MDI 2 to PC.
  3. Install an approved battery maintainer or power supply that provides a steady and stable voltage to support the 12V system during SPS programming events.
  4. Access the Service Programming System (SPS) and follow the on-screen instructions.
  5. On the SPS Supported Controllers screen, select K179 Automated Driving Mapping Module - Programming and follow the on-screen instructions.
    6. NOTE:

    The Serial Data Authentication Configuration button is located in the following location:

    • To the left side of the SPS Supported Controllers screen in the TIS system.
    • In the lower right corner of the SPS Supported Controllers screen in the Techline Connect system.
  6. On the SPS Supported Controllers screen, select Serial Data Authentication Configuration button and follow the on-screen instructions.
  7. Ignition/Vehicle OFF, all access doors closed, all vehicle systems OFF, and all keys at least 3 m (9.8 ft) away from vehicle. Disconnect the scan tool from the vehicle. It may take up to 10 min for all vehicle systems to power down.
  8. Ignition ON/Vehicle In Service Mode.
  9. Using a scan tool, clear DTCs.
