- Turn ignition off. Connect scan tool to Data Link Connector (DLC). DLC is located on bottom of instrument panel, to left of brake pedal. See Figure . Turn ignition on. Using scan tool, attempt to communicate with all modules. If communication is established with all modules, go to next step. If communication is not established with any module, perform appropriate test under COMMUNICATIONS under SYSTEM TESTS.
- Using scan tool, retrieve Diagnostic Trouble Codes (DTC) from all modules. Do not clear DTCs until repairs are complete. 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 corresponding symptom test(s) under affected system under SYSTEM TESTS . See SYMPTOM IDENTIFICATION table.
NOTE:
Scan tool messages are listed by system affected and not by module retrieved from.
