Using Malfunction Indicator Light (MIL)
- Note location of MIL on instrument cluster, left of tachometer. The MIL may also be referred to as the CHECK ENGINE or SERVICE ENGINE SOON light.
- Cycle ignition on, off, on, off and back on within 5 seconds. Count number of times MIL flashes on and off. Number of flashes represents the DTC. There is a slight pause between the flashes to represent first and second digits of the DTC. If more than one DTC exists, there will be a 4-second pause between the DTCs.
- If any DTCs are displayed, perform appropriate diagnostic test. See DTC & TEST IDENTIFICATION table under DIAGNOSTIC TROUBLE CODE DEFINITIONS.
- After repair is complete, clear DTCs from PCM memory. See CLEARING DIAGNOSTIC TROUBLE CODES . If no DTCs are displayed, diagnose by symptom. See TEST NTC-1: NO TROUBLE CODE TEST MENU under DIAGNOSTIC TESTS.
