Flow of Diagnosis

There are 3 main control systems in Chrysler Vehicles:

Powertrain Control Module PCM in Computers and Control Systems Testing and Inspection

Transmission Control Module TCM in Transmission Control Systems Testing and Inspection

Body Control Module BCM or Central Timer Module CTM in Computers and Control Systems/Body Control Module Testing and Inspection

NOTE: If diagnostic procedures are not available at the component/system to be tested, check one of these 3 systems for information

All "P" codes are shown as they would be retrieved using the Chrysler Scan Tool DRB - Diagnostic Readout Box. Testing is provided for these codes only, no information is provided by Chrysler for unlisted "P" codes. Code numbers retrieved via a non-DRB (generic) scan tool may not match codes listed.

NOTE: Alldata users have reported success matching the code description retrieved via a non-DRB scan tool, to diagnostic procedures provided.
