6. CHECK DOOR SWITCH
Step Check Yes No
1 CHECK DOOR SWITCH CIRCUIT.
Measure the voltage between keyless entry
control module harness connector terminal
and chassis ground.
N
O
TE:
The voltage is not 0 V due to noise, etc.
Connector & terminal
(B176) No. 3 (+) — Chassis ground (
− ):
Is the voltage approx. less than
0 V when any one of the doors
or rear gate is opened?
Go to step 2. Go to step 3.
2 CHECK DOOR SWITCH CIRCUIT.
Measure the voltage between keyless entry
control module harness connector terminal
and chassis ground.
Connector & terminal
(B176) No. 3 (+) — Chassis ground (
− ):
Is the voltage more than 10 V
when all doors and rear gate
are closed?
The door switch is
OK.
Go to step 3.
3 CHECK DOOR SWITCH.
1) Disconnect the door switch harness con-
nector.
2) Measure the resistance between door
switch terminals.
Terminal
Door switch No. 1 — No. 3:
Rear gate latch switch No. 1 — No. 2:
Is the resistance more than 1
MΩ when the door switch is
pressed?
Go to step 4. Replace the door
switch.
4 CHECK DOOR SWITCH.
Measure the resistance between door switch
terminals.
Terminal
Door switch No. 1 — No. 3:
Rear gate latch switch No. 1 — No. 2:
Is the resistance less than 1 Ω
when the door switch is
released?
Check the harness
for open circuits or
shorts between
keyless entry con-
trol module and
door switch.
Replace the door
switch.
