Clearing Codes: Notes

The diagnostic trouble codes in the EBTCM memory are erased in one of three ways:

1. TECH 1 Method.
2. On-Board Diagnostics Method.
3. Ignition Cycle Default.

These three methods are detailed below. Whichever method is used, be sure to verify proper system operation and absence of codes when the clearing procedure is completed.

Codes cannot be cleared by unplugging the EBTCM, disconnecting the battery cables, or by turning the ignition off (except on the 50th cycle of ignition cycle default).
