Clearing DTCS

Use a scan tool to clear the DTCs in the EBCM memory. After clearing the codes, verify proper system operation. The EBCM will not permit DTC clearing until all DTCs have been displayed. DTCs cannot be cleared by disconnecting the battery cables, unplugging the EBCM, or turning OFF the ignition.
