a. Check the operation.
1. Using a speedometer tester, inspect the speedometer for allowable
indication error and check
the operation of the odometer.
USA (mph):
CANADA (km/h):
NOTICE:
Tire wear and tire over or under inflation will cause the indication error.
2. Check the deflection range of the speedometer indicator.
Reference: Below 0.5 km/h (0.3 mph)
2. INSPECT OUTPUT SIGNAL OF VEHICLE SPEED
a. Check the input signal wave form.
- Remove the combination meter with connectors still
connected.
- Connect the oscilloscope to terminal C7−36 and
body ground.
- Start the engine.
- Check the signal wave form.
OK:
Signal wave form generates.
HINT:
A wave form as shown on the left appears if the voltage is 12
V under the following conditions:
HINT:
As vehicle speed increases, the cycle of the signal wave form
narrows.
3. INSPECT TACHOMETER
a. Check the operation
1. Connect a tune−up test tachometer, and start the engine.
NOTICE:
- Reversing the connection of the tachometer will damage the
transistors and diodes inside.
- When removing or installing the tachometer, be careful not to drop
or subject it to heavy
shocks.
2. Compare the result of the test and tachometer indications.
