Door Unlock Detection Switch Circuit
CIRCUIT DESCRIPTION
The door unlock detection switch is built in the door lock motor assembly. This switch is ON when the door
lock knob is in the unlock position and OFF when the lock knob is in the lock position. The ECU detects the
door lock knob conditions in this circuit. It is used as one of the operating conditions for the key confinement
prevention function.

PRE±CHECK
1. DIAGNOSIS SYSTEM
(a) Check the indicator.
(1) Turn the ignition switch ON.
(2) Check that the CRUISE MAIN indicator light comes
ON when the cruise control main switch is turned
ON, and that the indicator light goes OFF when the
main switch is turned OFF.
HINT:
If the indicator check result is not normal, proceed to trouble-
shooting (See page BE±2) for the combination meter section.
(b) Check the DTC.
HINT:
If a malfunction occurs in the No. 1 vehicle speed sensor or ac-
tuator, etc. during cruise control driving, the ECU actuates
AUTO CANCEL of the cruise control and turns on and off the
CRUISE MAIN indicator light to inform the driver of a malfunc-
tion. At the same time, the malfunction is stored in memory as
a DTC.
(c) Output of DTC using diagnosis check wire.
(1) Turn the ignition switch ON.
(2) Using SST, connect terminals Tc and E
1 of DLC2.
SST 09843±18020
(3) Read the DTC on the CRUISE MAIN indicator light.
