Instrument Cluster Programming and Setup

Note: 

   • DO NOT program a control module unless directed to by a service procedure or a service bulletin. If the ECU is not properly configured with the correct calibration software, the ECU will not control all of the vehicle features properly.
   • 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 ECU damage may occur.
   • Stable battery voltage is critical during programming. Any fluctuation, spiking, over voltage or loss of voltage will interrupt programming. Install the EL-49642 SPS Programming Support Tool to maintain system voltage. If not available, connect a fully charged 12 V jumper or booster pack disconnected from the AC voltage supply. DO NOT connect a battery charger.
   • 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 power mode.
   • Clear DTCs after programming is complete. Clearing powertrain DTCs will set the Inspection/Maintenance (I/M) system status indicators to NO.

Replace and Program ECU or Reprogram ECU

Note: This procedure may require a USB flash drive. SPS will indicate if the flash drive is needed.

To program a replacement or an existing ECU, perform the following procedure:

  1. Install EL-49642
  2. Connect the USB flash drive to the SPS terminal/PC.
  3. Access the Service Programming System (SPS) and follow the on-screen instructions.
  4. On the SPS Supported Controllers screen, select Instrument Cluster - Prepare Control Module for Programming and follow the on-screen instructions. If the USB flash drive is needed perform steps 4.1 and 4.2. If the USB is not needed continue on to step 5.

    5. Note: SPS will indicate when it is safe to remove the flash drive from the SPS terminal.

    4.1. Physically remove the cluster while leaving the connector plugged in to access the USB port on the back of the cluster.
    4.2. Using cable EL-50344-2 from special tool kit EL-50334-50 , connect the USB flash drive to the instrument cluster.
  5. On the SPS Supported Controllers screen, select Instrument Cluster - Programming and follow the on-screen instructions.

    6. Note: If the USB flash drive was required, the instrument cluster will automatically copy files from the flash drive. The SPS screen will indicate 100% completion but SPS will not say programming successful yet, the instrument cluster may still be programming. The instrument cluster screen will display a progression indicator while it is copying files from the USB drive. Once all files are programmed, SPS will then indicate programming successful.

  6. On the SPS Supported Controllers screen, select Instrument Cluster - Setup and follow the on-screen instructions.
  7. On the SPS Supported Controllers screen, select Instrument Cluster - Configuration and follow the on-screen instructions.
  8. At the end of programming, choose the "Clear All DTCs" function on the SPS screen.

Unsuccessful Programming Recovery

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

  1. DO NOT turn the vehicle OFF. Ensure that all ECU, DLC and programming tool connections are secure and the TIS terminal operating software is up to date.
  2. Attempt to reprogram the ECU.
  3. If the ECU can still not be programmed, turn the vehicle OFF for at least one minute.
  4. Vehicle in Service Mode, attempt to reprogram the ECU. The ECU should program.
    5. ⇒If the ECU still cannot be programmed, replace the ECU.
