Either use a scan tool. Or disconnect the positive battery cable, ground it to the battery ground, turn the key on but don't start it, turn headlights on, then headlights off, turn key off, reconnect positive battery cable. Sure the cable is grounded for atleast 30 seconds to be sure all the capacitors I'm the pcm have fully discharged
