Using MIL
- Before entering on-board diagnostics, see SERVICE PRECAUTIONS . Turn ignition on, off, on, off and on within 5 seconds. Record 2-digit DTCs as displayed by flashing MIL. Go to next step.
- A constant repetition of short flashes indicates system is normal. If system is abnormal, signals will appear on MIL as long and short flashes. Long flashes represent tens; short flashes represent ones. For example, 4 long flashes and 3 short flashes indicate DTC 43. After recording DTCs, proceed to DIAGNOSTIC TROUBLE CODES (DTCS) .
NOTE:
Although other scan tools are available, manufacturers recommend using a proprietary scan tool to retrieve DTCs. Chrysler Corp. and Eagle recommend using Chrysler's Diagnostic Readout Box III (DRB III) scan tool. Mitsubishi recommends using Multi-Use Tester II (MUT II) scan tool.
