Service Information

Purpose

This bulletin provides a service procedure to reprogram the engine/powertrain control module (ECM/PCM) on certain 2007 Ascender vehicles. The new calibrations provide improved engine cooling fan clutch on-board diagnostics.

This service procedure should be completed on involved vehicles currently in dealer inventory as soon as possible but no later than December 15, 2006, at which time this bulletin will expire. 

Service Procedure

Determine the build date of the vehicle and use the following instructions to repair this condition.

The PCM should be reprogrammed using calibrations that were released on IDS Version 10 or newer.

The updated PCM calibrations were released on IDS Version 10 and newer. As always make sure your Tech 2 is updated with the latest software version. Refer to the Engine and Powertrain Control Module Programming and Setup procedures in the Service Manual for further information.

NOTE: Before reprogramming, check the battery condition to prevent a reprogramming error of any of the modules due to battery discharge. Battery voltage must be between 12 and 16 volts during reprogramming. If the vehicle battery is not fully charged, use jumper cables from an additional battery. Be sure to turn off or disable any system that may put a load on the battery, such as automatic headlamps, daytime running lamps, interior lighting, heating, ventilation, and air conditioning (HVAC) system, radio, engine cooling fan, etc. A programming failure or control module damage may occur if the battery voltage guidelines are not observed.

The ignition switch must be in the proper position. The Tech 2 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:

  1. The RS-232 communication cable port
  2. The connection at the data link connector (DLC)
  3. The voltage supply circuits

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.

  1. Verify the battery charge of 12 to 16 volts. The battery must be able to maintain the charge during programming. Use an additional jump battery if necessary.
  2. Use the normal "request method" through "Service Programming System" to request information from the vehicle.
  3. At the Techline Terminal, enter TIS SPS Programming System.
  4. Select Tech 2 from the "Select Diagnostic Tool" window.
  5. Select Reprogram ECU from the "Select Programming Process" window.
  6. Select Vehicle from the "Select ECU Location" window.
  7. Select Next to go to the "Preparing for Communication" instruction screen.
  8. Select Next to view the "Validate Vehicle ID Number" screen. If the vehicle ID number does not appear on the screen, manually insert the VIN into the VIN window of the "Validate Vehicle ID Number" screen.
  9. Select Next to view the "Supported Controllers" screen.
  10. Select PCM/VCM Powertrain/Vehicle Control Module from "Supported Controllers" window.
  11. Select Next to view the "Select Programming Type" window.
  12. Select Normal from the "Select Programming Type" window.
  13. Select Next to view the "Service Programming System Calibration Selection" screen.
  14. Select Next to view "Summary" screen.
  15. Verify that current and selected calibration information is displayed on the "Summary" screen.
  16. Select Next to download the calibration to the Tech 2.
  17. Back at the vehicle, enter "Service Programming Systems".
  18. Select Program ECU and follow the on-screen instructions.
  19. When programming is complete, turn the Tech 2 OFF.
  20. Turn the ignition switch to OFF.
  21. Wait 30 seconds and then turn the ignition switch to ON with the engine OFF.
  22. Go into "Diagnostics" and check for DTC codes.
  23. Clear all codes.
