Door Courtesy Switch Circuit
CIRCUIT DESCRIPTION
The door courtesy switch comes ON when the door is opened and goes OFF when door is closed. Further-
more. the door courtesy switch circuit has terminal +B connected inside the theft deterrent ECU . Battery
positive voltage is applied to terminal DSWD of the theft deterrent ECU when all doors are closed, i.e., when
the door courtesy switches of all doors are OFF.

8. ECU TERMINAL VALUES MEASUREMENT BY USING
TOYOTA BREAK±OUT±BOX AND TOYOTA HAND±
HELD TESTER
(a) Hook up the TOYOTA break±out±box and TOYOTA
hand±held tester to the vehicle.
(b) Read the ECU input/ output values by following the
prompts on the tester screen.
HINT:
TOYOTA hand±held tester has a ºSnapshotº function.
This records the measured values and is effective in the diagno-
sis of intermittent problems.
Please refer to the TOYOTA hand±held tester / TOYOTA
break±out±box operator's manual for further details.
