Reading and Clearing Diagnostic Trouble Codes

CLEARING ABS DIAGNOSTIC TROUBLE CODES

Use one of the two following methods in order to erase the DTCs in the EBCM/EBTCM memory:
^ The Scan Tool method
^ The ignition cycle default method
Verify the proper system operation and the absence of DTCs after completing the clearing procedure.
The following methods will not clear the DTCs:
^ Unplugging the EBCM/EBTCM
^ Disconnecting the battery cables
^ Turning off the ignition switch (except on an ignition cycle default)

Scan Tool Method
Use the following procedure in order to clear the DTCs with the Scan Tool:
1. Select DTCs for Diagnostic Trouble Codes.
2. View the DTCs.
3. After all of the DTCs have been displayed the Scan Tool will display the following question: CLEAR DTCs?
Answer: YES
4. The Scan Tool will display the following message: History Data Will Be Lost. Clear DTCs?
Answer: YES
5. This action will clear all DTCs

Drive Cycle Default
Existing DTCs automatically clear from the EBCM/EBTCM memory 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).
