EL-49642 SPS Programming Support Tool
For equivalent regional tools, refer to Special Tools.
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.
- Diagnostic Aids
-
The air bag indicator light may remain ON after the body control module (BCM), or SDM is replaced, and during the programming procedure for the BCM until after the procedure is completed. When installing a new SDM, there may be several DTCs set prior to programming. Once programmed, these DTCs should be history and can be cleared.
- Replace and Program ECU or Reprogram ECU
-
To program a replacement or an existing Inflatable Restraint Sensing and Diagnostic Module, perform the following procedure:
- Install EL-49642 SPS Programming Support Tool.
- Access the Service Programming System (SPS) and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select Inflatable Restraint Sensing and Diagnostic Module - Programming and follow the on-screen instructions.
- On the SPS Supported Controllers screen, select Inflatable Restraint Sensing and Diagnostic Module - Setup and follow the on-screen instructions.
- 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:
- 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.
- Attempt to reprogram the ECU.
- If the ECU can still not be programmed, turn the vehicle OFF for at least one minute.
- Vehicle in Service Mode, attempt to reprogram the ECU. The ECU should program.
- If the ECU still cannot be programmed, replace the ECU.

Throttle/Idle Learn
Description
The engine control module (ECM) learns the airflow through the throttle body
to ensure the correct idle. The learned airflow values are stored within the
ECM. These values are learned to adjust for production variation and will continuously
