Self-Diagnostic System

WARNING: This page is about a different car, the 2000 Dodge Ram Wagon and 2000 Dodge Ram Van. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: System tests are written specifically for Chrysler's Diagnostic Readout Box (DRBIII®) scan tool. A generic scan tool may not be capable of performing all necessary test functions.
  1. Perform pretest inspection. See PRETEST INSPECTION  under TROUBLE SHOOTING. If pretest inspection procedure has been performed, go to next step.
  2. Turn ignition off. Connect scan tool to Data Link Connector (DLC). Turn ignition on. If scan tool display is not blank, go to next step. If scan tool display is blank, see SCAN TOOL BLANK SCREEN  under COMMUNICATIONS under SYSTEM TESTS.
  3. Using scan tool, select SYSTEM MONITORS, then CCD BUS TEST. Scan tool will perform a CCD bus test. If scan tool displays BUS OPERATIONAL, go to next step. If scan tool displays any message except BUS OPERATIONAL, see appropriate test under COMMUNICATIONS  under SYSTEM TESTS.
  4. NOTE: Scan tool messages are listed by system affected and not by module retrieved from.
  5. Using scan tool, select READ DTCs. If any DTCs exist, perform corresponding DTC test(s) under affected system under SYSTEM TESTS . See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table. If no DTCs exist, repair by performing appropriate symptom test(s) under SYSTEM TESTS . See SYMPTOM IDENTIFICATION  table.
