Unlock Relay

CIRCUIT OPERATION
Circuit M1 from the Ignition Off Draw (IOD) fuse in cavity 9 of the fuse block powers circuit P38. When either power door lock switch is put in the UNLOCK position, the switch connects circuit P38 to circuit P36. If the operator uses Remote Keyless Entry (RKE), the RKE module powers circuit P36. In either case, circuit P36 supplies power to the coil side of the unlock relay, causing the relay contacts to connect circuits P37 and P34. Circuit Z1 provides ground for the coil side of the unlock relay.

When the unlock relay contacts connect circuit P37 to circuit P34, circuit P34 supplies battery voltage to the power door lock motors to UNLOCK the doors.

When the power doors UNLOCK, ground for the motors is on circuit P2 through the door lock relay to ground on circuit Z1.
