Enhancements To Vehicle Operation - Reprogram ECM/TCM - Service Action S937

This service action supersedes Service Actions S926 and S931.
(Technical bulletins XT307-S926 and XT412-S931.)

Issue:

A significant change has been introduced in production to the programming of the Engine Control Module (ECM) and for automatic transmission vehicles, the Transmission Control Module (TCM) that provides a perceptable enhancement to the vehicle's operation.

On manual transmission vehicles, the ECM should be reprogrammed to the latest condition using Worldwide Diagnostic System (WDS) release JTP 759/23A or later. On automatic transmission vehicles, the ECM and TCM should be reprogrammed to the latest condition using Worldwide Diagnostic System (WDS) release JTP 759/23A or later.

It is intended that this Service Action be carried out in conjunction with Recall Action R935 Direction Indicator Tell Tale Operation.

This Service Action supersedes the following campaigns:

^ XT307-S926 Degradation of Shift Quality

^ XT412-S931 A/C System Failure Due to Incorrect Engine Management Software

Action:

Perform these reprograming procedures on any 2002-03 MY X-TYPE vehicle, within the above VIN range, on which they have not already been carried out.
