Hybrid Powertrain Control Module 2 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.

Programming a New Control Module

To program a new control module, perform the following procedure:

    Caution: DO NOT program the K114B Hybrid/EV Powertrain Control Module 2 with the drive motor battery charger cable connected to the vehicle. Charging while programming may result in damage to the High Voltage Battery Disconnect Relays.

  1. Install the special tool:<sptool><sptool-no>EL-49642</sptool-no><sptool-desc>SPS Programming Support Tool</sptool-desc></sptool>
  2. Access the Service Programming System (SPS) and follow the on-screen instructions.
  3. On the SPS Supported Controllers screen, select K114B Hybrid/Electric Vehicle Powertrain Control Module 2 - Programming and follow the on-screen instructions.
  4. At the end of programming, choose the "Clear All DTCs".
  5. With a scan tool, perform the Hybrid/EV Battery Pack Capacity Learn and follow the on-screen instructions.
  6. With a scan tool, select the Passenger Compartment Heater Coolant Control Solenoid Valve Learn Procedure and follow the on-screen instructions.
  7. With a scan tool, perform the Clear Secured High Voltage DTCs and follow the on-screen instructions.
  8. With a scan tool, Clear All DTCs.
  9. With a scan tool, select Hybrid/EV Battery Pack Charging Adaptive Learn Reset in the K114B Hybrid/Electric Vehicle Powertrain Control Module 2 Reset Functions menu and follow the on-screen instructions.
Programming an Existing Control Module

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

    Caution: DO NOT program the K114B Hybrid/EV Powertrain Control Module 2 with the drive motor battery charger cable connected to the vehicle. Charging while programming may result in damage to the High Voltage Battery Disconnect Relays.

  1. Install the special tool:<sptool><sptool-no>EL-49642</sptool-no><sptool-desc>SPS Programming Support Tool</sptool-desc></sptool>
  2. Access the Service Programming System (SPS) and follow the on-screen instructions.
  3. On the SPS Supported Controllers screen, select K114B Hybrid/Electric Vehicle Powertrain Control Module 2 - Programming and follow the on-screen instructions.
  4. At the end of programming, choose the "Clear All DTCs".
Unsuccessful Programming Recovery

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

  1. Ignition ON. Ensure the control module, DLC and programming tool connections are secure and the SPS software is up to date.
  2. Attempt to reprogram the ECU.
    • If the programming is not successful
    1. Ignition OFF for 1 minute, ignition ON.
    2. Attempt to reprogram the ECU.
      • If the programming is not successful » Replace the component:K114B Hybrid/Electric Vehicle Powertrain Control Module 2
      • If the programming is successful
    3. All OK.
    • If the programming is successful
  3. All OK.
