Using Malfunction Indicator Light (MIL)

USING MALFUNCTION INDICATOR LIGHT (MIL)
If suitable tester is not available, stored trouble codes can be accessed directly through the MIL. To call up codes, cycle ignition switch on, off, on, off and on within 5 seconds. Stored codes will be indicated by flashes of the MIL. The codes will be indicated as two digit numbers, with a four second pause between codes. An example of a code is as follows:

1. Malfunction Indicator (Power Loss/Check Engine) Lamp illuminated for approximately 2 to 3 seconds as a bulb check, then turns off.
2. Lamp flashes two times, pauses, then flashes six times.
3. Lamp pauses for approximately four seconds.
4. Lamp flashes three times, pauses, then flashes one time.
5. This would indicate that code 26 and 31 are stored. The lamp will continue to flash until all stored codes have been displayed.

Once the lamp starts flashing the stored diagnostic trouble codes, it cannot be stopped. If a code is missed, the entire procedure must be repeated. The lamp also cannot be used to perform actuation test mode, sensor test mode or engine running test mode.
