Service Programming System (SPS): Programming

WARNING: This page is about a different car, the 2009 Saturn Vue. However, it is still accessible from the selected car via links, so may be relevant.

Vehicle system voltage:
- There is not a charging system concern. All charging system concerns must be repaired before programming a control module.
- Battery voltage is greater than 12 volts but less than 16 volts. The battery must be fully charged before programming the control module.
- Turn OFF or disable any system that may put a load on the vehicles battery, such as the following components:
  - Twilight sentinel
  - Interior lights
  - Daytime running lights (DRL)-Applying the parking brake, on most vehicles, disables the DRL system
  - Heating, ventilation, and air conditioning (HVAC) systems
  - Engine cooling fans, radio, etc.
The ignition switch must be in the proper position. SPS prompts you to turn ON the ignition, with the engine OFF. DO NOT change the position of the ignition switch during the programming procedure, unless instructed to do so.
Make certain all tool connections are secure, including the following components and circuits:
- Scan Tool
  - The RS-232 communication cable port
  - The connection at the data link connector (DLC)
  - The voltage supply circuits
- MDI
  - The USB, Ethernet or Wireless communication port
  - The connection at the data link connector (DLC)
DO NOT disturb the tool harnesses while programming. If an interruption occurs during the programming procedure, programming failure or control module damage may occur.
DO NOT turn OFF the ignition if the programming procedure is interrupted or unsuccessful. Ensure that all control module and DLC connections are secure and the TIS terminal operating software is up to date. Attempt to reprogram the control module. If the control module cannot be programmed, replace the control module.
