Retrieving Diagnostic Trouble Codes
NOTE:
If Malfunction Indicator Light (MIL) is illuminated and NO BUS is displayed in the odometer display on instrument cluster, this indicates that instrumet cluster has lost bus communication with Powertrain Control Module (PCM). Repair communication problem between instrument cluster and PCM before proceeding. See BODY CONTROL MODULES - BREEZE, CIRRUS, SEBRING CONVERTIBLE & STRATUS article in ACCESSORIES & EQUIPMENT.
NOTE:
Ensure battery is fully charged before retrieving diagnostic trouble codes.
- Turn ignition off. Connect scan tool to Data Link Connector (DLC). DLC is located below driver's side of instrument panel, near driver's side kick panel. See Fig 1 .
- Turn ignition on with engine off. Using scan tool manufacturer's instructions, read and record Diagnostic Trouble Code (DTC) message (DRB scan tool) or DTC code (generic scan tool) and freeze frame data. On any scan tool, if scan tool displays NO RESPONSE, perform TEST NS-1: NO RESPONSE CONDITION . If scan tool will not power up, check for loose cable connections or bad cable. If cable connections or cable are defective, repair or replace components as necessary and then recheck for DTCs. If cable connections and cable are okay, using voltmeter, check voltage at cavity No. 16 (Pink/White wire) on DLC. Voltage should be at least 11 volts. If voltage is not as specified, check for defective fuse No. 5 (10-amp), as this fuse supplies voltage to cavity No. 16 on data link connector. Fuse No. 5 is located in junction block on end of driver's side of instrument panel, near door opening. It may also be necessary to check for defective fuse No. 4 (20-amp), as this fuse supplies voltage to fuse No. 5. Fuse No. 4 is located in power distribution center at driver's side front corner of engine compartment, near air cleaner assembly. If necessary, check wiring circuit between fuse No. 5, fuse No. 4 (20-amp) and the battery. See DATA LINK CONNECTORS and POWER DISTRIBUTION articles in WIRING DIAGRAMS. If voltage exists at cavity No. 16 (Pink/White wire) on DLC but scan tool will not power up and blank screen exists, it may be necessary to ensure that good ground exists at terminal No. 4 (Black/Violet wire) on DLC. For ground circuit wiring, see GROUND DISTRIBUTION article in WIRING DIAGRAMS.
- Note DTC messages and codes. See DIAGNOSTIC TROUBLE CODE DEFINITIONS .
- If scan tool displays an error message, (i.e., USER-REQUESTED COLD BOOT or USER-REQUESTED WARM BOOT), follow scan tool manufacturer's instructions. If scan tool displays a bus failure, this indicates either a scan tool failure or bus failure. To diagnose and correct bus failures, see COMMUNICATIONS under SYSTEM TESTS in BODY CONTROL MODULES - BREEZE, CIRRUS, SEBRING CONVERTIBLE & STRATUS article in ACCESSORIES & EQUIPMENT.
- Perform appropriate test for displayed DTCs. See appropriate DTC test listed under DIAGNOSTIC TESTS . Once all repairs are made, ensure DTCs are cleared from PCM. See CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM.
- If no DTCs are displayed, refer to one of the following:
- For driveability problems, perform TEST NTC-1: NO TROUBLE CODE TEST MENU located after DTC tests under DIAGNOSTIC TESTS.
- For no-start problems, perform TEST NS-SEL: NO START TEST SELECTION located after No Trouble Code (NTC) tests following DTC tests under DIAGNOSTIC TESTS.
- For speed control problems and additional servicing information, see appropriate CRUISE CONTROL SYSTEMS article in ACCESSORIES & EQUIPMENT.
- For charging system problems and additional servicing information, see appropriate GENERATORS & REGULATORS article in STARTING & CHARGING SYSTEMS.
NOTE: If MIL remains on steady and no DTCs exist, check instrument cluster for diagnosis of MIL. See INSTRUMENT CLUSTER SYSTEMS under SYSTEM TESTS in BODY CONTROL MODULES - BREEZE, CIRRUS, SEBRING CONVERTIBLE & STRATUS article in ACCESSORIES & EQUIPMENT.
