INSPECTION
1. INSPECT SPEEDOMETER ON±VEHICLE
Using a speedometer tester, inspect the speedometer for allow-
able indication error and check the operation of the odometer.
HINT:
Tire wear and tire over or under inflation will increase the indica-
tion error.
If error is excessive, replace the speedometer.

2. INSPECT VEHICLE SPEED SENSOR OPERATION
(a) Connect the positive (+) lead from the battery to terminal
1 and negative (±) lead to terminal 2.
(b) Connect the positive (+) lead from the tester to terminal
3 and the negative (±) lead to terminal 2.
(c) Rotate the shaft.
(d) Check that there is voltage change from approx. 0 V to
11 V or more between terminals 2 and 3.
HINT:
The voltage change should be performed 4 times for every rev-
olution of the speed sensor shaft.
If operation is not as specified, replace the sensor.
3. INSPECT TACHOMETER ON±VEHICLE
(a) Connect a tune±up test tachometer, and start the engine.
NOTICE:

Reversing the connection of the tachometer will dam-
age the transistors and diodes inside.

When removing or installing the tachometer, be care-
ful not to drop or subject it to heavy shocks.
