Clearing Diagnostic Trouble Codes

The DTCs in the EBCM/EBTCM memory are erased in one of two ways:
^ DTCs are erased by the scan tool method.
^ DTCs are erased by ignition cycle default. This requires 100 ignition cycles to pass with no detection of the DTCs.

Always verify the proper system operation and always verify absence of DTCs when the clearing procedure is completed.
The following methods will not clear DTCs:
^ DTCs cannot be cleared by unplugging the EBCM/EBTCM.
^ DTCs cannot be cleared by disconnecting the battery cables.
^ DTCs cannot be cleared by turning the ignition switch to the OFF position. However, DTCs can be cleared on the 100th cycle of the ignition cycle default.
