Component Tests and General Diagnostics

ON-VEHICLE INSPECTION







1. INSPECT SPEEDOMETER
a. Check the operation.
1. Using a speedometer tester, inspect the speedometer for acceptable indication error and check the operation of the odometer.
Reference: km/h (Canada)

NOTE: Tire wear and over or under tire pressure will affect the indication error.

2. Check the deflection width of the speed meter indicator.
Reference: Below 0.5 km/h (0.3 mph)




2. INSPECT OUTPUT SIGNAL OF VEHICLE SPEED
a. Check for the signal.
1. While driving the vehicle at 10 km/h, check the voltage between the terminal C9-1 and C9-18 of the combination meter assembly.
Standard: Fluctuation between 7.7 to 14 V or less is repeated 7 times within 1 sec.

NOTE: Check it with the ignition switch turned to the ON position and the connector connected.

3. INSPECT TACHOMETER
a. Check operation
1. Connect the tune-up test tachometer, and start the engine.

NOTE:
- Reversing the connection of the tachometer will damage the transistors and the insides of the diodes.
- When removing or installing the tachometer, be careful not to drop or subject it to heavy shocks.




2. Compare the result of the test with the standard indication.
DC 13.5 V, 25 °C (77 °F)





4. MAINTENANCE LIQUID RESETTING PROCEDURE
a. Set tne display window to ODO.
b. Turn the ignition switch off.
c. While pressing the reset switch, turn the ignition switch to ON. Keep pressing the reset switch for at least 5 seconds to complete the reset procedure. Check that the "OIL MAI NT" indicator light goes off.

HINT:
- If the ignition switch is turned off during the reset procedure:
LCD: off
IND: off
- If the reset switch is not pressed for at least 5 seconds during the reset procedure:
LCD: return to ODO
IND: previous state
