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.

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.)

3) Turn ignition switch and select monitor switch ON.
4) After display is shown, press slash“/”key.
5) After AT mode is displayed, press function“[0]”.
(Display returns to AT mode when slash“/”is pressed during
on-board diagnostic operation.)

3. PREVIOUS TROUBLE CODE READING
1) Connect select monitor.
2) Designate mode using function key.
Press [F] [B] [1] [ENT] in that order.
3) Ensure displayed trouble code(s).
USING AN OSCILLOSCOPEA malfunction can be determined by displaying the waveforms
of input/output signals on the oscilloscope.
Diagnosis
A simple comparison of the waveforms may lead to an incor-
rect diagnosis. To exactly determine the sources of the mal-
function it will be necessary to determine them under consider-
ation about information other than waveforms.
Applying input/output signals
Connect the probe directly with the terminal of the signal.
