Diagnostic Tests: Notes

CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.

NOTE: Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRBIII(R)) scan tool. A generic scan tool may not be capable of performing all necessary test functions.

NOTE: If using a generic scan tool or using DRBIII scan tool in generic scan tool mode, Powertrain Control Module (PCM) may stop communications with scan tool. This applies to vehicles with a build date prior to 11-30-99. It may appear that sensor values are not updating on generic scan tool. This condition may occur at any time during communications between PCM and generic scan tool. If this condition occurs, see technical service bulletin No. 08-39-99 for recommended repair procedure.
