Diagnostic Procedure

NOTE: Self-diagnostic tests are written specifically for Chrysler's Diagnostic Readout Box (DRB) scan tool. If using a generic scan tool, ensure scan tool is OBD-II certified. A generic scan tool may not be capable of performing all necessary test functions.

If no faults were found while performing checks in BASIC DIAGNOSTIC PROCEDURES article, proceed with self-diagnostics. Always perform a visual inspection before attempting to diagnose engine control system problems. See VISUAL INSPECTION . Retrieve DTCs using scan tool only. See RETRIEVING DTCS .
