NOTE: Before proceeding, ensure battery voltage is more than 11 volts with ignition on. If DTC confirmation procedure had been previously run, turn ignition off and wait at least 10 seconds before continuing.

Turn ignition on. Select DATA MONITOR mode with CONSULT-II or generic scan tool. Start engine and allow to idle 2 seconds. If DTC is detected, go to DIAGNOSTIC PROCEDURE . If DTC is not detected, system is okay at this time.
