Ignition Shut Down Relay (For Antitheft): Testing and Inspection

CIRCUIT DESCRIPTION

When the theft deterrent system is activated, contact "a" in the ECU becomes open, creating an open circuit in terminal SRLY circuit and making the starter inoperative (starter cut).
In this condition, if one of the following operations is done, the contact "a" in the ECU is grounded, thus canceling the starter cut:
1. Unlock the LH or RH door with key.
2. Unlock the doors with the wireless door lock control system.
