Diagnostic Procedures
- If OBD system check has been performed, go to next step. If OBD system check has not been performed, see ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK under SELF-DIAGNOSTIC SYSTEM.
- Turn ignition off. Disconnect Engine Shutoff (ESO) solenoid harness connector. Turn ignition on. Using test light connected to ground, probe ignition feed circuit at ESO solenoid harness connector. If test light illuminates, go to next step. If test light does not illuminate, go to step 6.
- Turn ignition off. Using test light, jumper ESO solenoid harness connector terminals together. Turn ignition on. If test light illuminates, go to next step. If test light does not illuminate, go to step 7.
- Using test light connected to battery positive, probe control circuit at ESO solenoid harness connector. Turn ignition on. Using scan tool, command ESO solenoid on and off. If test light turns on and off with each command, go to next step. If test light does not turn on and off with each command, go to step 8.
- Check ESO solenoid harness connector for poor connections. Repair as necessary. After repairs, go to step 13. If connections are okay, go to step 11.
- Check ESO solenoid ignition feed circuit for open or faulty fuse. Repair as necessary. After repairs, go to step 13.
- Using test light connected to ground, probe control circuit at ESO solenoid harness connector. Turn ignition on. If test light illuminates, go to step 10. If test light does not illuminate, go to step 9.
- Repair short to ground in ESO solenoid control circuit. After repairs, go to step 13.
- Check ESO solenoid control circuit for open or poor connection at PCM. Repair as necessary. After repairs, go to step 13. If circuit and connections are okay, go to step 12.
- Check ESO solenoid control circuit for short to voltage. Repair as necessary. After repairs, go to step 13. If circuit is okay, go to step 12.
- Replace ESO solenoid. See ENGINE SHUTDOWN SOLENOID REPLACEMENT After repairs, go to step 13.
- Replace PCM. Perform PCM relearn procedures. See PROGRAMMING . After repairs, go to next step.
- Using scan tool, clear DTCs. Start and warm engine to normal operating temperature. Select DTC, SPECIFIC, and then enter DTC P0215. Operate vehicle within the conditions for setting this DTC. If scan tool indicates that this test ran and passed, go to next step. If scan tool does not indicate that this test ran and passed, go to step 2.
- Using scan tool, check for DTCs. If any undiagnosed DTCs are set, perform appropriate DTC test. If no DTCs are set, system is okay.
