Self-Diagnostic System

WARNING: This page does not describe the selected car, but rather 7 other vehicles, including the 2000 Plymouth Voyager, 2000 Plymouth Grand Voyager, 2000 Dodge Grand Caravan, 2000 Dodge Caravan, and 2000 Chrysler Voyager. However, it is still accessible from the selected car via links, so may be relevant.
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.
  1. If pretest inspection procedure has been performed, go to next step. If pretest inspection procedure has not been performed, perform pretest inspection. See PRETEST INSPECTION  under TROUBLE SHOOTING.
  2. Turn ignition off. Connect scan tool to Data Link Connector (DLC). DLC is located under driver's side of instrument panel, right of steering column. Turn ignition on. Using scan tool, attempt to communicate with all modules. If communication was established with all modules, go to next step. If communication was not established with any module, perform appropriate test under COMMUNICATIONS  under SYSTEM TESTS.
    NOTE: Codes are listed by system affected, not from module retrieved. Perform appropriate test under appropriate section under SYSTEM TESTS.
  3. Using scan tool, retrieve Diagnostic Trouble Codes (DTCs) from all modules. If any DTCs exist, perform appropriate test(s). See DIAGNOSTIC TROUBLE CODE IDENTIFICATION  table. If no DTCs exist, repair by symptom. See SYMPTOM IDENTIFICATION  table.
