Step
Check
Yes
No
1
CHECK POWER SUPPLY.
1) Turn the ignition switch to OFF.
2) Disconnect the harness connector from
cruise control actuator.
3) Turn the ignition switch to ON.
4) Turn the cruise control main switch to ON.
5) Measure the voltage between cruise control
actuator harness connector terminal and chas-
sis ground.
Terminals
(B7) No. 4 (+) — Chassis ground (
−
):
Is the voltage more than 10 V? Go to step
Check the harness
for open or short
between cruise
control module
and cruise control
actuator.
2
CHECK GROUND CIRCUIT OF ACTUATOR.
1) Turn the ignition switch and cruise control
main switch to OFF.
2) Measure the resistance between cruise
control actuator harness connector terminal
and chassis ground.
Terminals
(B7) No. 6 — Chassis ground:
Is the resistance less than 10
Ω
?
Repair the har-
ness.
3
MEASURE RESISTANCE OF ACTUATOR
CLUTCH.
Measure the resistance of cruise control actua-
tor clutch.
Terminals
No. 3 — No. 6:
Is the resistance approx. 39
Ω
Replace the cruise
control actuator.
<Ref. to CC-5,
Actuator.>
4
CHECK HARNESS BETWEEN ACTUATOR
AND CRUISE CONTROL MODULE.
1) Disconnect the harness connector from
cruise control module.
2) Measure the resistance between cruise
control module harness connector terminal
and cruise control actuator harness connector
terminal.
Connector & terminal
(B7) No. 2 — (B94) No. 13:
Is the resistance less than 10
Ω
?
Repair the har-
ness.
5
CHECK HARNESS BETWEEN ACTUATOR
AND CRUISE CONTROL MODULE.
Measure the resistance between cruise control
module harness connector terminal and cruise
control actuator harness connector terminal.
Connector & terminal
(B7) No. 3 — (B94) No. 14:
Is the resistance less than 10
Ω
?
Replace the cruise
control module.
<Ref. to CC-7,
Cruise Control
Module.>
Repair the har-
ness.
