3) Start the engine.
4) Shift on the gear position, and keep the vehicle speed
at constant.
5) Measure signal voltage.
Specified voltage (V): 2 V, or more
NOTE:

If the vehicle speed increases, the width of amplitude
(W) decreases.

If oscilloscope is not available, check input signal
(vehicle speed signal) by using a select monitor. (Refer to
the procedure as described below.)

Using the select monitor:
(1) Set the vehicle on free roller, or lift-up the vehicle and
support with safety stands.
(2) Turn ignition switch to OFF and set select monitor.
(3) Turn ignition switch to ON.
(4) Turn cruise control main switch to ON.
(5) Set select monitor in“F01”or“F02”mode.
(6) Drive the vehicle at speed greater than 40 km/h (25
MPH).
(7) Check that vehicle speed indication on select moni-
tor and speedometer are equal.
NOTE:

When there is a disconnection or short circuit in the har-
ness between the meter and the cruise control module, the
indicated value will be 0 to 1.0 km/h (0 to 0.6 MPH).

In“F01”mode, vehicle speed is indicated in mile per
hour (MPH).
In“F02”mode, vehicle speed is indicated in kilometer per
hour (km/h).

3. PERFORM A CIRCUIT TEST BETWEEN
COMBINATION METER AND CRUISE CONTROL
MODULE.
1) Turn ignition switch to OFF.
2) Remove combination meter.
B6M0194B
3) Disconnect connector from cruise control module.
4) Measure resistance of harness connector between
combination meter and cruise control module.
Connector & terminal / Specified resistance:
(i10) No. 10—(B94) No. 19 / 10Ω, max.

5) Measure resistance of harness connector between
cruise control module and body to make sure that circuit
does not short.
Connector & terminal / Specified resistance:
(B94) No. 19—Body / 1 MΩ, min.
B3M0289
4. CHECK VEHICLE SPEED SENSOR 2.
1) Disconnect connector from vehicle speed sensor 2.
2) Measure resistance between terminals of vehicle speed
sensor 2.
Terminals / Specified resistance:
No. 1—No. 2 / 350—450Ω
B3M0256
WARNING:
Be careful not to be caught up by the running wheels.
3) Set the vehicle on free roller, or lift-up the vehicle and
support with safety stands.
4) Drive the vehicle at speed greater than 20 km/h (12
MPH).
5) Measure voltage between terminals of vehicle speed
sensor 2.
Terminals / Specified voltage:
No. 1—No. 2 / 2 V, or more (AC range)
B3M0257

Using an oscilloscope:
(1) Turn ignition switch to OFF.
(2) Set oscilloscope to vehicle speed sensor 2.
(3) Drive the vehicle at speed greater than 20 km/h (12
MPH).
(4) Measure signal voltage.
Specified voltage (V): 5 V, min.

F: TROUBLE CODE 23 AND 24
—CRUISE CONTROL MODULE BUILT-IN
RELAY, CPU RAM—
DIAGNOSIS:

Welding of built-in relay of cruise control module.

Failure of built-in CPU RAM of cruise control module.
TROUBLE SYMPTOM:

Cruise control is cancelled and memorized cruise speed
is also cancelled.

Once cruise control is cancelled, cruise control cannot
be set until the ignition switch and cruise main switch turns
OFF, and then turns ON again.
NOTE:
Perform real-time diagnosis (“FA 0”mode) and check
vehicle speed signal with select monitor.
When input signals are in good condition, failure is in cruise
control module.
(Check power supply and ground condition of cruise con-
trol module.)
