Diagnostic System Check
- Install scan tool. If scan tool powers up, go to next step. If scan tool does not power up, perform appropriate diagnostic procedure. See SELF-DIAGNOSTIC SYSTEM in appropriate BODY CONTROL MODULES article.
- Turn ignition on. Following scan tool manufacturer's instructions, attempt to establish communication with Driver Door Module (DDM) and Powertrain Control Module (PCM). If communication with DDM and PCM is established, go to next step. If communication with DDM and PCM is not established, diagnose communication problem with class 2 device. See SELF-DIAGNOSTIC SYSTEM in appropriate BODY CONTROL MODULES article.
- Select display DTC function for DDM and PCM. Record all displayed DTCs, status of displayed DTCs and module that set the DTC. If DTCs are displayed, go to next step. If no DTCs are displayed, diagnose by symptom. See SYMPTOM TESTS
.
- Retrieve DTCs and perform appropriate test. See DIAGNOSTIC TROUBLE CODE INDEX
table.
