K69 Transfer Case Control Module: Programming and Setup

Note:

  • Always verify the module has the newest software available before replacing the module.
  • Verify 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 programming. 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 vehicle's battery. For example, interior lights, daytime running lights, HVAC, and radio.
  • During the programming procedure, follow the Service Programming System (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.

Unsuccessful Programming Recovery

If programming a control module is not successful, perform the following procedure:

  1. Verify the control module, data link connector and programming tool connections are secure and the tool software is up to date.
  2. Perform the SPS function:K69 Transfer Case Control Module—Programming

    Verify the control module programming is successful.

    • If the programming is not successful
    1. Disconnect the battery.
    2. Wait 60 s before proceeding to the next step.
    3. Connect the battery.
    4. Perform the SPS function:K69 Transfer Case Control Module—Programming
      • If the programming is not successful » Replace the component:K69 Transfer Case Control Module
      • If the programming is successful
    5. Select Serial Data Authentication Configuration button (located to the left of the SPS supported controllers list or to the bottom right of the Techline Connect) and follow the on-screen instructions.
    6. Perform the SPS function:K69 Transfer Case Control Module—Setup
      • If the programming is not successful » Replace the component:A16 Transfer Case Four Wheel Drive Actuator

        Perform the SPS function:K69 Transfer Case Control Module—Setup

      • If the procedure was successful
    7. Perform the scan tool function:Range Actuator Learn
