On-Vehicle Inspection

WARNING: This page is about a different car, the 2008 Toyota RAV4. However, it is still accessible from the selected car via links, so may be relevant.

CHECK SPEEDOMETER

Check the operation.

Using a speedometer tester, check that the speedometer reading is within the allowable range shown in the table below. Also, check for proper operation of the odometer.

Reference: km/h (Except for U.S.A.)

ACCEPTABLE RANGE

Standard indication	Acceptable range
20 km/h	17.5 to 21.5 km/h
40 km/h	38 to 42 km/h
60 km/h	58 to 63 km/h
80 km/h	78 to 84 km/h
100 km/h	98.5 to 104.5 km/h
120 km/h	119 to 125 km/h
140 km/h	139 to 146 km/h
160 km/h	159 to 167 km/h
180 km/h	179 to 188 km/h
200 km/h	199 to 209 km/h
220 km/h	219 to 230 km/h
240 km/h	239 to 251 km/h

Reference: mph (U.S.A.)

ACCEPTABLE RANGE

Standard indication	Acceptable range
20 mph	20 to 23.0 mph
40 mph	40 to 43.5 mph
60 mph	60 to 64.0 mph
80 mph	80 to 84.5 mph
100 mph	100 to 105.0 mph
120 mph	120 to 125.5 mph
140 mph	140 to 146.0 mph

CAUTION: Do not use worn, under inflated or over inflated tires, as the speedometer reading will be inaccurate.

Check the deflection width of the speedometer indicator.
Reference:

Below 0.5 km/h (0.3 mph)

CHECK OUTPUT SIGNAL OF VEHICLE SPEED SENSOR

Check the output signal waveform.

Remove the combination meter, but do not disconnect the connector.
Connect an oscilloscope to terminal E19-39 and the body ground.
Start the engine.

Check the signal waveform according to the condition(s) in the table below.

WAVEFORM REFERENCE

Item	Condition
Tool setting	5 V/DIV, 20 ms/DIV
Vehicle condition	Driving at approx. 20 km/h (12.4 mph)

OK:

Waveform is as shown in the illustration.

HINT:

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

Fig 1: Checking Output Signal Of Vehicle Speed Sensor

CHECK TACHOMETER

Check the operation.

Connect the tune-up test tachometer, and start the engine.
CAUTION:
- 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 strike it.

Compare the result of the test with the standard indication.

Reference: DC 13.5 V, at 25°C (77°F)

ACCEPTABLE RANGE

Standard indication (rpm)	Acceptable range (rpm) Data in () are for reference
700	630 to 770
1,000	(900 to 1,100)
2,000	(1,850 to 2,150)
3,000	2,800 to 3,200
4,000	(3,800 to 4,200)
5,000	4,800 to 5,200
6,000	(5,750 to 6,250)
7,000	6,700 to 7,300
8,000	(7,700 to 8.300)

CHECK FUEL RECEIVER GAUGE
1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, then check the position of the receiver gauge needle.
  OK:
  
  Needle position is on EMPTY.
3. Connect terminals 1 and 2 on the wire harness side connector of the fuel sender gauge.
4. Turn the ignition switch ON, then check the position of the receiver gauge needle.
  OK:
  
  Needle position is on FULL.

CHECK FUEL LEVEL WARNING LIGHT
1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch ON, check that the fuel level needle indicates EMPTY and fuel level warning light comes on.
  OK:
  
  Fuel level warning light comes on.
CHECK BRAKE WARNING LIGHT
1. Inspect the parking brake warning light.
  1. Disconnect the connector from the parking brake switch.
  2. Turn the ignition switch ON.
  3. Ground the terminal of the wire harness side connector, and then check that the parking brake warning light illuminates.
    OK:
    
    Parking brake warning light illuminates.
CHECK OIL PRESSURE WARNING LIGHT
1. Disconnect the connector from the engine oil pressure switch.
2. Turn the ignition switch ON.
3. Ground the terminal of the wire harness side connector, then check the engine oil pressure warning light.
  OK:
  
  Engine oil pressure warning light comes on.
CHECK WASHER LEVEL WARNING SWITCH
1. Disconnect the connector from the washer level warning switch.
2. Turn the ignition switch ON.
3. Ground the terminal of the wire harness side connector, then check the washer level warning light.
  OK:
  
  Washer level warning light comes on.
