CHECK CRUISE CONTROL COMMAND
SWITCH CIRCUIT.
1) Remove the driver’s airbag module. <Ref. to
AB-15, REMOVAL, Driver’s Airbag Module.>
2) Disconnect the harness connector of cruise
control command switch.
3) Turn the ignition switch to ON.
4) Measure the voltage between harness con-
nector terminal and chassis ground.
Connector & terminal
(ST3) No. 8 (+) — Chassis ground (–):
(ST3) No. 7 (+) — Chassis ground (–):
Is the voltage 5 V or more?
Check the harness
between cruise
control command
switch and ECM,
and the steering
roll connector for
open or short cir-
cuit, or for poor
contact.

CHECK CRUISE CONTROL COMMAND
SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Remove the cruise control command
switch. <Ref. to CC-6, REMOVAL, Cruise Con-
trol Command Switch.>
3) Measure the resistance between harness
connector terminal and chassis ground.
Connector & terminal
(ST3) No. 6 — Chassis ground:
Is the resistance less than 10
Ω?
Check for open cir-
cuit between
cruise control com-
mand switch,
ECM, and chassis
ground and check
the ECM.
3
CHECK CRUISE CONTROL COMMAND
SWITCH.
Measure the resistance between switch termi-
nals when the cruise control command switch is
not depressed.
Terminals
No. 6 — No. 7:
Is the resistance approx. 4 kΩ? Go to step
Replace the cruise
control command
switch. <Ref. to

No. 6 — No. 7:
Is the resistance approx. less
than 1 Ω when the CANCEL
switch is pressed?
Replace the cruise
control command
switch. <Ref. to

trol Command
Switch.>
6
CHECK RESUME/ACCEL SWITCH CIRCUIT.
Measure the resistance between switch termi-
nals with the RESUME/ACCEL switch pressed.
Terminals
No. 6 — No. 7:
Is the resistance approx. 1,500
Ω when RESUME/ACCEL
switch is pressed?
Replace the cruise
control command
