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
- Use the scan tool "Clear DTCs" selection.

The method is 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 disconnecting the EBCM, disconnecting the battery cables, or turning the ignition switch to LOCK.

Scan Tool Method

The scan tool can clear ABS 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.
