6. CHECK DOOR SWITCH
Step
1 CHECK DOOR SWITCH CIRCUIT.
Measure the voltage between the body inte-
grated unit harness connector terminal and
chassis ground.

(i84) No. 32 (+) — Chassis ground (–):
Front door LH:
(i84) No. 19 (+) — Chassis ground (–):
Rear door RH:
(i84) No. 18 (+) — Chassis ground (–):
Rear door LH:
(i84) No. 31 (+) — Chassis ground (–):
Rear gate:
(i84) No. 17 (+) — Chassis ground (–):

3 CHECK DOOR SWITCH.
1) Disconnect the door switch harness con-
nector (R9, R12, R16, R22).
2) Measure the resistance between door
switch terminals.

Check
Is the voltage 0 V when each
door or rear gate is opened?
Is the voltage more than 10 V
when each door or rear gate is
closed?
Is the resistance more than 1
MΩ when door switch is
pushed?
Is the resistance less than 1 Ω
when door switch is released?
