SELF-DIAGNOSTIC SYSTEM

CAUTIONWhen 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.

PRETEST INSPECTION

Before proceeding with diagnosis, the following precautions must be followed

  1. Ensure self-diagnostic tests apply to vehicle being tested. See BODY CONTROL COMPUTER TESTS DIRECTORY table.
  2. Vehicle must have a fully charged battery and functional charging system.
  3. Always start at TEST 1A: IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS. Starting with any other test may result in incorrect results.
  4. Only perform test steps indicated. It is NOT necessary to perform all steps in a test.
  5. Always start at TEST 1A.
  6. Turn ignition switch to OFF position before disconnecting or connecting components.
  7. Use extreme care when connecting or disconnecting wiring during testing to prevent accidental grounding or shorting.
  8. DO NOT use a test light in place of a voltmeter.
  9. Always disconnect scan tool after use.
  10. Always disconnect scan tool before charging battery.
  11. Always perform TEST VER-1 after repairs are made.

DIAGNOSTIC PROCEDURE

Note. Before proceeding with diagnosis, certain precautions must be followed. See PRETEST INSPECTION under SELF-DIAGNOSTIC SYSTEM.

ENTERING ON-BOARD DIAGNOSTICS

Note. While using DRB scan tool, if an error is made or technician is unaware of correct procedures, enter "F1" (Help) or HOW TO USE DRB from various menus.

  1. Before entering on-board diagnostics, refer to «PRETEST INSPECTION»(ref-11041-S24169819612000111300000). Turn all accessories off. Turn ignition off. Attach appropriate 1995 cartridge to scan tool. Connect scan tool to Data Link Connector (DLC). see scheme 1
  2. Turn ignition on. Start engine (if possible). With foot on brake, move transmission shift lever through all positions, ending in Park (A/T) or Neutral (M/T). Turn A/C switch on then off (if equipped).
  3. Turn ignition off. Without starting engine again, turn ignition on. Enter No. 1, STAND ALONE DRB. Enter selection No. 1, CHRYSLER DOMESTIC. Enter selection No. 1, ENGINE. Proceed until READ DTCS selection is offered. After DTCs are accessed, go to «TEST 1A - IDENTIFYING VEHICLE EQUIPMENT & SYSTEM PROBLEMS»(ref-11041-S13141058762000111300000) to diagnose problem.
  4. To erase DTCs while in this mode, press BACK key. At scan tool display, scroll to YES - ERASE DTCS. A confirmation message should appear, DTCS ERASED.

SCAN TOOL PROBLEMS & ERROR MESSAGES

For scan tool problems and/or error messages, proceed to appropriate BODY CONTROL COMPUTER. Always start at TEST 1A. Testing of NO RESPONSE messages may be found in appropriate BODY CONTROL COMPUTER TESTS.

  3. After each repair, perform TEST VER-1. CAUTION: Always turn ignition switch to OFF position before disconnecting or connecting any module connector.
  1. Turn ignition off. Disconnect traveler module. Traveler module is located behind right side of dash, below glove box. Using an external ohmmeter, check resistance between traveler module terminals No. 1 and 2.
  2. If resistance is not 100-140 ohms, replace traveler. If resistance is 100-140 ohms, check resistance of Violet/Brown wire between traveler module connector terminal No. 1 and Data Link Connector (DLC) terminal No. 6. If resistance is more than 5 ohms, repair open Violet/Brown wire.
  3. If resistance is less than 5 ohms, check resistance of White/Black wire between traveler module connector terminal No. 2 and DLC terminal No. 4. If resistance is more than 5 ohms, repair open White/Black wire.
  4. If resistance is less than 5 ohms, reconnect scan tool. Using scan tool in voltmeter mode, check voltage on traveler connector terminal No. 5 (White wire). If voltage is less than 10 volts, repair White wire as necessary.
  5. If voltage is more than 10 volts, using scan tool in ohmmeter mode, check resistance of visual message center connector ground circuit (Black wire). If resistance is more than 5 ohms, repair open Black wire. If resistance is less than 5 ohms, replace traveler module.

Note. A break in test sequence occurs at this point. No test procedures have been omitted.

  2. «WIRING DIAGRAMS - 3.5L»(ref-11019)
  3. After each repair, perform TEST VER-1. CAUTION: Always turn ignition switch to OFF position prior to disconnecting or connecting any module connector.
  1. Using scan tool, indicate whether vehicle is equipped with specific module. See «MODULE APPLICATIONS»(ref-11041-S31756664082000111300000) table. Turn ignition off. Disconnect Transmission Control Module (TCM), if equipped. TCM is located on left side of engine compartment, near cowl. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace TCM.
  2. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Powertrain Control Module (PCM). PCM is located between Data Link Connector (DLC) and battery, on fenderwell. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace PCM.
  3. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Controller Anti-Lock Brake (CAB), if equipped. CAB is located on left fenderwell of engine compartment, behind anti-lock brake pump motor. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace CAB.
  4. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, disconnect traveler module, if equipped. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace traveler module.
  5. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Mechanical Instrument Cluster (MIC) or Electronic Instrument Cluster (EIC). Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace MIC or EIC.
  6. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Vehicle Theft Alarm (VTSS) module, if equipped. VTSS module is located in back of glove box. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace VTSS module.
  7. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect compass/mini-trip module, if equipped. Compass/mini-trip module is located at center of roof, above visors. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace compass/mini-trip module.
  8. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off. Disconnect Infinity CD player. Turn ignition on. If scan tool does not display NOT RECEIVING MESSAGES CORRECTLY, replace CD player.
  9. If scan tool displays NOT RECEIVING MESSAGES CORRECTLY, turn ignition off and wait 2 minutes. CAUTION: Ensure ignition is off for 2 minutes before proceeding.
  10. Disconnect Air Bag System Control Module (ABSCM). ABSCM is located under center of instrument panel. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES INCORRECTLY, replace ABSCM.
  11. If scan tool displays NOT RECEIVING BUS MESSAGES INCORRECTLY, turn ignition off and disconnect ATC head (A/C-heater control panel), if equipped. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace ATC head.
  12. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Overhead Traveler Information System (OTIS) module, if equipped. OTIS module is located at center of roof, above visors. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace OTIS module.
  13. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, turn ignition off and disconnect Body Control Module (BCM), if equipped. BCM is located behind right kick panel.
  14. Turn ignition on. If scan tool does not display NOT RECEIVING BUS MESSAGES CORRECTLY, replace BCM. If scan tool displays NOT RECEIVING BUS MESSAGES CORRECTLY, replace scan tool cable or cartridge as necessary.
  1. Reconnect all components that were previously disconnected. Ensure ignition is off and scan tool is connected. Turn ignition on, engine off. If scan tool screen is blank, go to «TEST 2A»(ref-11041-S39542251962000111300000) . If scan tool screen is not blank, go to next step.
  2. Using scan tool, perform BUS test. If there is a bus failure message on scan tool, go to TEST 1A. If there is no bus failure message on scan tool, select module in question. If scan tool shows NO RESPONSE, go to TEST 1A.
  3. If scan tool does not show NO RESPONSE, inspect vehicle for original complaint. If original complaint is present, go to TEST 1A. If original complaint is not present, repair is complete.
