On-Vehicle Inspection

1. 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) 

      REFERENCE
      
      

      Standard indication	Acceptable range
      20 km/h	18.0 to 22.0 km/h
      40 km/h	38.0 to 42.0 km/h
      60 km/h	58.0 to 62.0 km/h
      80 km/h	78.0 to 82.0 km/h
      100 km/h	97.0 to 103.0 km/h
      120 km/h	117.0 to 123.0 km/h
      140 km/h	137.0 to 143.0 km/h
      160 km/h	157.0 to 163.0 km/h

      Reference: mph (U.S.A) 

      REFERENCE
      
      

      Standard indication	Acceptable range
      20 mph	18.0 to 22.0 mph
      40 mph	38.0 to 42.0 mph
      60 mph	59.0 to 63.0 mph
      80 mph	79.0 to 83.0 mph
      100 mph	99.0 to 104.0 mph
      120 mph	119.0 to 125.0 mph

      NOTE: Tire wear and over or under tire pressure will affect indication error.
   2. Check the deflection width of the speedometer indicator.

   Reference: Below 0.5 km/h (0.3 mph) 

1. Check the output signal waveform.
   1. Remove the combination meter assy.
   2. Connect the oscilloscope to the terminals C10-13 and body ground.
   3. Start the engine.

   4. Check the signal waveform according to the condition in the table below.

OK: 

As shown in the illustration 

HINT:

As vehicle speed increases, the cycle of the signal waveform narrows.

1. Disconnect the connector from the sender gauge.
2. Turn the power switch ON (IG) position, then check the position of the receiver gauge needle.

   OK: 

   Needle position is on (EMPTY). 

3. Connect terminals 5 and 6 on the wire harness side connector of the fuel sender gauge.
4. Turn the power switch to the ON (IG) position, then check the position of the receiver gauge needle.

   OK: 

   Needle position is on (FULL).

1. Disconnect the connector from the sender gauge.
2. Turn the power switch ON (IG) position, then check that the fuel level needle indicates EMPTY and the fuel level warning light comes on.

   OK: 

   EMPTY (The No.1 segment blinks). 

1. Disconnect the connector from the low oil pressure switch.
2. Turn the power switch ON (IG) position.
3. Ground the terminal of the wire harness side connector, then check the master warning light.

   OK: 

   Master warning light comes on. 

1. Inspect the parking brake warning light.
   1. Disconnect the connector from the parking brake switch.
   2. Turn the power switch ON (IG) position.
   3. Ground the terminal of the wire harness side connector, then check the parking brake warning light.

   OK: 

   Brake warning light comes on. 

2. Inspect the brake fluid level warning light.
   1. Disconnect the connector from the brake fluid level warning switch.
   2. Turn the power switch ON (IG) position.
   3. Connect a terminal to the other terminal of the wire harness side connector, then check the brake fluid level warning switch.

   OK: 

   Brake warning light comes on. 

1. Remove the reservoir tank cap and strainer.
2. Disconnect the connector.
3. Measure the resistance between the terminals.

   Standard: 

   Float up (switch off): 10 kΩ or higher 

4. Use a syphon, etc. to take fluid out of the reservoir tank.
5. Measure the resistance between the terminals.

   Standard: 

   Float down (switch on): Below 1 Ω 

6. Pour the fluid back in the reservoir tank.
7. Reconnect the connector.

Indicator Condition: 

1. Set the display window to ODO.
2. Turn the power switch off.
3. Pressing the reset switch, turn the power switch to the ON (IG) position (keep pressing for at least 5 seconds).
4. Reset procedure is completed.

HINT:

• If the power switch is turned off during reset procedure, reset mode is canceled.
• If the reset switch is turned off during the reset procedure, reset mode is canceled and the display shows the condition prior to the reset procedure.

Perform the following procedures to correct inclination of the meter and inclination sensors when installing/removing/replacing the meter or after replacing the inclination sensors or main base.

1. Setting procedure
   1. Connect the connector and install the meter securely in the position as shown in the illustration so that it is inclined at a 20 degree angle to the vehicle's vertical line A.

   2. Park vehicle on a level surface.
   3. Turn the power switch ON (IG) position.
   4. Place the odometer display into the "TRIP A" mode.
   5. Turn OFF the power switch.
   6. Depress and hold the ODO/TRIP button while pressing the power switch twice (IG). (Do not put your foot on the brake.)
   7. Depress and hold the ODO/TRIP button 3 times within 5 seconds:

      Release - Press - Release - Press - Release - Press and Hold. Continue to hold the ODO/TRIP button for at least 5 seconds until the Inclination Sensor Information is displayed on the Odometer.

   8. Release the ODO/TRIP button.
   9. Depress and hold the ODO/TRIP button for at least 5 seconds to update the centered value.

      The third digit will indicate the status. The value of "1" indicates a successful reset.

      HINT:

      If "0", "2", or "3" is displayed, perform the procedure from step (3) again.

   10. Release the ODO/TRIP button. (Once the reset is complete, the odometer will returns to normal.)
   11. Turn OFF the power switch.
