2001 Buick Regal Engine Control Module Parts and Q&A

• Q: Should You Program an Existing Engine Control Module with the Identical Software/Calibration Package Before Programming a New Engine Control Module on 2001 Buick Regal?

  A: Do not utilize the same control module software/calibration package on an existing module since it has no effective solution for driveability conditions. The programming of control modules must follow two conditions: the replacement directive from service teams or incoming software/calibration updates from general motors corporation. The programming process requires proper vehicle system voltage between 12 and 16 volts with no charging system faults and without battery charger access to prevent programming problems and control module destruction. Reducing the vehicle battery load requires turning off daytime running lights (DRL), heating ventilation and air conditioning (HVAC) and cooling system fans along with all other systems that could drain the battery. Proper connection at the dlc and rs-232 interface should be present while the Ignition Switch needs to be placed in the position indicated by the scan tool. Taking care to leave the tool harnesses untouched will stop problems from arising that might cause programming failure or control module damage. The battery of a notebook computer used for pass-through programming requires a full charge when operating without the power cord.
