Important!
Update the PCM operating software only on vehicles produced PRIOR to the specified VIN above. The update CD-ROM is only intended for use by authorized dealership personnel, and is not to be released or sold. The CD-ROM can be used repeatedly to address the above mentioned conditions on the specified VINs. Handle the update CD-ROM carefully, so the recorded side does not become scratched or soiled. Avoid leaving finger prints on the CD-ROM, and only grasp it by the edges, or the center hole. When not in use, always store the CD-ROM in it's protective case. Do not store the CD-ROM in damp or hot conditions, as this will reduce it's operating life. Avoid direct sunlight. Only clean the CDROM with approved commercial products designed exclusively for CD-ROMs. Never use petroleum based solvents, or anti-static products on the CD-ROM disk.
Parts Information:
The update CD ROM will be shipped automatically, but only to dealers with affected vehicles in their area of responsibility (AOR). Call Technical Services if you were not supplied with a CD-ROM and one is needed. Phone numbers: (770) 290-3645, or (770) 290-3647.
Work Procedure:
Updating the PCM operating system with supplied CD-ROM:
1. Remove the ignition key.
2. Switch on the PCM by pressing the volume control knob (arrow A).
3. Remove navigation CD from the PCM disk drive. Insert the update CD into the PCM CD drive.

Note:
