Reading and Clearing Diagnostic Trouble Codes

DISPLAYING DIAGNOSTIC TROUBLE CODES
Diagnostic Trouble Codes (DTCs) can be read through the use of the Scan Tool. There are no provisions for flash code diagnostics.

CLEARING DIAGNOSTIC TROUBLE CODES (DTCs)
The DTCs in Electronic Brake Control Module (EBCM) memory is erased in one of two ways:
1. Scan Tool.
2. Ignition cycle default.

These two methods are detailed below. Be sure to verify proper system operation and absence of DTCs when the clearing procedure is completed. The EBCM will not permit DTC clearing until all DTCs have been displayed. Also, DTCs cannot be cleared by unplugging the EBCM, disconnecting the battery cables, or turning the ignition to off (except on an ignition cycle default).

Scan Tool Method
Select DTC for diagnostic trouble codes. After DTCs have been viewed completely, follow the menu to clear DTCs.

Drive 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 EBCM memory.
