Starter Relay Circuit
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 can-
celing the starter cut:
(1) Unlock the front LH or RH door with key.
(2) Unlock the doors with the wireless door lock control system.
