Clearing Diagnostic Trouble Codes

METHODS OF ERASING CODES
Two methods of erasing Diagnostic Trouble Codes (DTC)s are detailed below. Be sure to verify proper system operation and absence of DTCs when the clearing procedure is completed.

NOTE:
- The scan tool will not permit DTC clearing until all DTCs have been displayed.
- DTCs cannot be cleared by unplugging the Electronic Brake/Traction Control Module (EBCM/EBTCM), disconnecting the battery cables, or turning the ignition off (except on an ignition cycle default).

Scan Tool Method
The scan tool method is the only method to be used when servicing a vehicle. Select DTC(s) for diagnostic trouble codes. After DTCs have been viewed completely, scan tool will ask, (CLEAR DTCs?); answer yes. Scan tool will then read, (HISTORY DATA WILL BE LOST. CLEAR DTCs?) Answer yes and DTCs will be cleared.

Ignition Cycle Default
If no diagnostic trouble codes occur for 100 drive cycles, (a drive cycle occurs when the ignition is turned to RUN and the vehicle is driven faster than 16 km/h (10 mph), any existing DTCs are automatically cleared from the EBTCM memory.
