Engine Controls Self-Diagnostics - 2.2L: Programming: Notes

NOTE: DO NOT program an existing PCM with the identical software/calibration package. This procedure is not a short cut to correct a driveability condition. This is an ineffective repair. A PCM should only be programmed when a service procedure instructs you to replace the PCM. The service part PCM does not contain operating software or calibrations or General Motors Corporation releases an updated software/calibration package.

After replacing Powertrain Control Module (PCM) or if program needs to be updated, refer to latest Techline(R) information on PCM reprogramming. PCM can only be programmed using Tech 2 and Techline(R) terminal, or by using a personal computer equipped with the current service programming system software installed.
