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. 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 programing. 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 vehicles battery such as; interior lights, exterior lights (including daytime running lights), and HVAC.
- During the programming procedure, follow the 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.
- To prevent programming failure due to unintended wireless drops, it is important that a wired MDI connection be used when reprogramming the Instrument Cluster
Diagnostic Aids
The programming steps in the Service Programming System (SPS) screens may not be in functional order. It is mandatory to follow the programming steps in the order listed below. The steps must be completed for the Instrument Cluster to be fully functional. Reversing the order or completing only one step could cause the Instrument Cluster to malfunction. If the steps are completed in an incorrect order, performing the steps in the proper
order will correct the malfunctions.
Replace and Program ECU (except Cadillac)
To program a replacement or a new ECU, perform the following procedure:
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster – Programming, Setup and Configuration and follow the on-screen instructions.
Note:
- The USB File Transfer procedure is performed after the new Instrument Cluster is installed in the vehicle. This procedure requires the use of a USB memory stick. The radio must be on during this procedure. The USB File Transfer procedure is not required for vehicles with UDC.
- Software currently loaded on the USB Drive will be verified and if files are incorrect they will be deleted and correct files will be loaded. If files residing on the USB Drive are correct for the vehicle being serviced, the Techline terminal will not delete those files and allow the drive to be re-used.
- The USB File Transfer procedure is normally performed with the Ignition ON/Vehicle in Service Mode. If USB File Transfer fails in Ignition ON/Vehicle in Service Mode, attempt USB File Transfer again with the engine running.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster – USB File Transfer and follow the on-screen instructions. When prompted after installing files in vehicle via USB memory stick, select UPDATE on radio display. When update is complete, select DISMISS and remove the USB memory stick.
- At the end of programming, choose the “Clear All DTCs” function on the SPS screen.
Replace and Program ECU (Cadillac)
To program a replacement or a new ECU, perform the following procedure:
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster – Programming and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster – Setup and Configuration and follow the on-screen instructions.

- On the SPS Supported Controllers screen, select P16 Instrument Cluster – USB File Transfer and follow the on-screen instructions. When prompted after installing files in vehicle via USB memory stick, select UPDATE on radio display. When update is complete, select DISMISS and remove the USB memory stick.
- At the end of programming, choose the “Clear All DTCs” function on the SPS screen.
Reprogram ECU (except Cadillac)
To program an existing ECU, perform the following procedure:
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select P16 Instrument Cluster – Programming, Setup and Configuration and follow the on-screen instructions.
Note:
- The USB File Transfer procedure is performed after the new Instrument Cluster is installed in the vehicle. This procedure requires the use of a USB memory stick. The radio must be on during this procedure. The USB File Transfer procedure is not required for vehicles with UDC.

Unsuccessful Programming Recovery
In the event of an interrupted or unsuccessful programming event, perform the following steps:
- DO NOT turn the ignition OFF. Ensure that all ECU, DLC and programming tool connections are secure and the TIS terminal operating software is up to date.
- Attempt to reprogram the ECU using the Replace and Program ECU instructions above.
- If the ECU can still not be programmed, turn the ignition OFF, disconnect battery, and wait for 15 minutes.
- Connect battery, turn the ignition ON and attempt to reprogram the ECU using the Replace and Program ECU instructions above. The ECU should program.
- If the ECU still cannot be programmed, replace the ECU.
