On-Vehicle Inspection

1. Check the operation.
   1. Using a speedometer tester, inspect the speedometer for allowable indication error and check the operation of the odometer.

      Reference: km/h (Europe)

      NOTE: Tire wear and tire over or under inflation will increase the indication error.
   2. Check the deflection width of the speed meter indicator.

      Reference: Below 0.5 km/h (0.3 MPH) 

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

1. Check for standard signal.
   1. While driving the vehicle at the speed of 10 km/h, check the voltage between the terminals C11-15 of the combination meter assy and body ground.

      Standard: Fluctuation between 10 to 14 V or less is repeated 7 times within 1 sec. 

1. Check the operation.
   NOTE:
   • 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. 
   1. Connect a tune-up test tachometer, and start the engine.
   2. Compare the test and tachometer indications.

1. Inspect the circuit.
   1. Disconnect the connector from the sender gauge.
   2. Turn the ignition switch ON, then check the position of the receiver gauge needle.

      Needle Position: EMPTY 

   3. Connect terminals 2 and 3 on the wire harness side connector of fuel sender gauge and between terminals on the wire harness side.

   4. Turn the ignition switch ON, then check the position of the receiver gauge needle.

Needle Position: FULL 

1. Inspect the circuit.
   1. Disconnect the connector from the sender gauge.
   2. Turn the ignition switch ON, check the fuel level needle indicates EMPTY and fuel level warning lights light on.

1. Inspect the circuit.
   1. Disconnect the connector from the sender gauge.
   2. Turn the ignition switch ON, check the position of the water temperature receiver gauge needle.

      Needle Position: COOL 

   3. Ground terminal 2 on the wire harness side, then check the position of the water temperature receiver gauge needle.

Needle Position: HOT 

1. Check the operation.
   1. Turn the ignition switch ON and check that the warning light lights up.
   2. Fasten the outer belt to the inner belt and check that the warning light lights out.
   3. Disconnect the connector from the buckle switch and ground terminal on the wire harness side connector.
   4. Turn the ignition switch ON and check that the warning light lights up.

1. Inspect the circuit.
   1. Disconnect the connector from the low oil pressure switch.
   2. Turn the ignition switch ON.
   3. Connect the terminal of wire harness side connector and ground, then check the warning low oil pressure warning light.

Low oil pressure warning light: Light on 

1. Inspect the parking brake warning light.
   1. Disconnect the connector from the parking brake switch and ground terminal on the wire harness side connector.
   2. Turn the ignition switch ON and check that the warning light lights up.
2. Inspect the brake fluid level warning light.
   1. Disconnect the connector from the brake fluid level warning switch and connect terminals on the wire harness side connector.
   2. Turn the ignition switch ON and check that the warning light lights up.

1. Inspect the continuity.
   1. Remove the reservoir tank cap and strainer.
   2. Disconnect the connector.
   3. Check that the continuity exists between the terminals.

      Float up (switch off): No continuity 

   4. Use siphon, etc., to take fluid out of the reservoir tank.
   5. Check that the continuity exists between the terminals.

      Float down (switch on): Continuity 

   6. Pour the fluid back in the reservoir tank.
   7. Check that the buzzer stop after about 4 to 8 seconds.

1. Check warning buzzer function.
   1. Turn the ignition switch ON and check that the key reminder warning sounds if the ignition key is insert the key cylinder and front driver side door is opened.
