INSPECTION PROCEDURE
1 Check operation of speedometer.
CHECK:
Drive the vehicle and check if the function of the speedometer in the combination meter is normal.
OK:
Actual vehicle speed and the speed indicated on the speedometer and the same.
HINT:
The vehicle speed sensor is functioning normally when the indication on the speedometer is normal.
NG Check combination meter assy
(See page DI±1645).
OK
2 Inspect combination meter assy.
PREPARATION:
Disconnect the radio and navigation assy connector.
CHECK:
(a) Move the shift lever to the neutral position.
(b) Jack up either one of the front wheels.
(c) Turn the ignition switch on.
(d) Measure the voltage between terminal SPD and body
ground of the radio and navigation assy when the front
wheels are turned slowly.
OK:
Voltage is pulses as shown below.
OK Replace radio and navigation assy.
