1
CHECK CRUISE CONTROL COMMAND
SWITCH CIRCUIT.
1) Remove the driver’s airbag module. <Ref. to
AB-14, 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?
Go to step 2.
Check for open,
shorted circuit, or
poor contact of
harness between
cruise control com-
mand switch and
ECM and steering
roll connector.
2
CHECK CRUISE CONTROL COMMAND
SWITCH CIRCUIT.
1) Turn the ignition switch to OFF.
2) Remove the cruise control command
switch. <Ref. to CC-5, 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
:? Go to step 3.
Check for open
between cruise
control command
switch and 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 k
:? Go to step 4.
Replace the cruise
control command
switch.
<Ref. to CC-5,
Cruise Control
Command
Switch.>
4
CHECK CANCEL SWITCH.
1) Turn the ignition switch to OFF.
2) Remove the cruise control command
switch. <Ref. to CC-5, REMOVAL, Cruise Con-
trol Command Switch.>
3) Measure the resistance between switch ter-
minals with the CANCEL switch pressed.
Terminals
No. 6 — No. 7:
Is the resistance approx. less
than 1
: when the CANCEL
switch is pressed?
Go to step 5.
Replace the cruise
control command
switch.
<Ref. to CC-5,
Cruise Control
Command
Switch.>
5
CHECK SET/COAST SWITCH.
Measure the resistance between switch termi-
nals with the SET/COAST switch pressed.
Terminals
No. 6 — No. 7:
Is the resistance approx. 250
:
when SET/COAST switch is
pressed?
Go to step 6.
Replace the cruise
control command
switch. <Ref. to
CC-5, Cruise Con-
trol Command
Switch.>
6
CHECK RESUME/ACCEL SWITCH CIRCUIT.
Measure the resistance between switch termi-
nals when the RESUME/ACCEL switch is
pressed.
Terminals
No. 6 — No. 7:
Is the resistance approx. 1,500
:
when RESUME/ACCEL switch
is pressed?
Replace the ECM.
