5. FUSE No. 16, AIRBAG MAIN HARNESS, BODY
HARNESS VIBRATION INSPECTION
Conduct vibration inspection on fuse No. 16, airbag main
harness and body harness.
CAUTION:
Do not shake or vibrate airbag control module.
: Do fuse No. 16, airbag main harness or
body harness malfunction again when shak-
ing?

2. CHECK INPUT SIGNAL FOR CRUISE CONTROL
MODULE.
WARNING:
Be careful not to be caught up by the running wheels.
1) Set the vehicle on free roller, or lift-up the vehicle and
support with safety stands.
2) Set oscilloscope to cruise control module connector ter-
minals.

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.
