Without Scan Tool

Be sure to verify proper system operation and absence of codes when the clearing procedure is completed.

The EBCM will not permit code clearing until all codes have been displayed. Also, codes cannot be cleared by unplugging the EBCM, disconnecting the battery cables, or turning the ignition "OFF" (except on an ignition cycle default).

Ignition Cycle Default
This method is discussed for informational purposes only. Do not use this method to clear codes during diagnosis.

If no diagnostic trouble code occurs for 100 drive cycles (a drive cycle occurs when the ignition is turned "ON" and the vehicle is driven faster than 13 km/h [10 mph]), any existing codes are cleared from the EBCM memory.
