For 1990-2009 cars

Use a scan tool in order to clear Diagnostic Trouble Codes (DTCs). Complete the Diagnostic System Check before clearing the DTCs. Verify the proper system operation and the absence of DTCs after you have completed the clearing procedure. The Electronic Brake Control Module (EBCM) will not permit you to clear DTCs until all DTCs have been displayed and the malfunction is corrected. The following methods will not clear the DTCs:

• | Unplugging the EBCM

• | Disconnecting the battery cables

• | Turning the ignition switch to the LOCK position

### Scan Tool Method

1. Connect a scan tool to the OBD2 Data Link Connector (DLC).
2. Turn the ignition switch to ON position.
3. Select S platform from the Chassis Menu.
