Reading and Clearing Diagnostic Trouble Codes

Except Code 41

1. Turn ignition switch Off, then disconnect battery ground cable or ECU-B fuse for 10 seconds or more.
2. When connecting battery after cancelling malfunction code, ensure ignition switch in Lock position. If battery cable is connected with ignition switch in On or ACC position, diagnosis system may malfunction.
3. The lower the temperature, the longer the battery ground cable must be left off.

Code 41

This code clearing method may be used for all codes.
