How to Clear Diagnostic Trouble Codes

CLEARING DTCs
Tools Required
Scan Tool
The diagnostic trouble codes (DTCs) in the electronic brake control module (EBCM) memory are erased in one of two ways:
- Use the scan tool "Clear DTCs" selection.
- After 249 DTC-free ignition cycles.
These two methods are detailed below. Be sure to verify the proper system operation and, the 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 disconnecting the EBCM, disconnecting the battery cables, or turning the ignition switch to LOCK.

Scan Tool Method
The scan tool can clear ABS/TCS system DTCs using the mass storage cartridge.
1. Install the scan tool and the mass storage cartridge.
2. Select "Fault Memory."
3. Select "Clear Fault Memory."
Clearing the fault memory cannot reset a valve relay which was shut down when the fault was recognized. Changes are possible only after the fault has been eliminated and the next ignition cycle has begun.

Ignition Cycle Default
A DTC is erased from memory after 249 ignition cycles without any reappearance of that malfunction.
