On-Vehicle Inspection

WARNING: This page is about a different car, the 2004 Toyota Camry Solara. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT SPEEDOMETER

Check the operation.

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

Reference: km/h (Canada)

SPEED RANGE (CANADA)

Standard indication	Acceptable range
20 km/h	17.5 to 21.5 km/h
40 km/h	38.0 to 42.0 km/h
60 km/h	58.0 to 63.0 km/h
80 km/h	78.0 to 84.0 km/h
100 km/h	98.5 to 104.5 km/h
120 km/h	119.0 to 125.0 km/h
140 km/h	139.0 to 146.0 km/h
160 km/h	159.0 to 167.0 km/h
180 km/h	179.0 to 188.0 km/h
200 km/h	199.0 to 209.0 km/h
220 km/h	219.0 to 230.0 km/h
240 km/h	239.0 to 251.0 km/h

Reference: mph (U.S.A)

SPEED RANGE (USA)

Standard indication	Acceptable range
20 mph	20.0 to 23.0 mph
40 mph	40.0 to 43.5 mph
60 mph	60.0 to 64.0 mph
80 mph	80.0 to 84.5 mph
100 mph	100.0 to 105.0 mph
120 mph	120.0 to 125.5 mph
140 mph	140.0 to 146.0 mph

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

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

INSPECT OUTPUT OF VEHICLE SPEED

Check the output signal waveform.

Remove the combination meter assy.
Connect the oscilloscope to terminal C7-36 and body ground.

Start the engine.
Check the signal waveform according to the condition(s) in DC 13.5 V STANDARD INDICATION .

DC 13.5 V STANDARD INDICATION

Item	Condition
Tool setting	5 V/DIV, 20 ms/DIV
Vehicle condition	Driving at approx. 20 km/h (12 mph)

OK:

As shown in Fig 2

HINT:

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

INSPECT TACHOMETER

Check the operation

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

DC 13.5 V STANDARD INDICATION

Standard indication (r/min)	3MZ-FE: Acceptable range (r/min) Data in ( ) are for reference	2AZ-FE: Acceptable range (r/min) Data in ( ) are for reference
700	630 to 770	618 to 758
1,000	900 to 1100)	883 to 1083
2,000	1850 to 2150)	1817 to 2117

4,000	3800 to 4200)	3733 to 4133
5,000	4800 to 5200	4717 to 5117
6,000	5800 to 6200)	5650 to 6150
7,000	6800 to 7200	6583 to 7183

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

INSPECT FUEL LEVEL WARNING
1. Disconnect the connector from the sender gauge.
2. Turn the ignition switch to the ON position, then check that the fuel level needle indicates EMPTY and the fuel level warning light comes on.
  OK:
  
  Fuel level warning light comes on.
INSPECT LOW OIL PRESSURE WARNING LIGHT
1. Disconnect the connector from the low oil pressure switch.
2. Turn the ignition switch to the ON position.
3. Ground the terminal of the wire harness side connector, then check the low oil pressure warning light.
  OK:
  
  Low oil pressure warning light comes on.
INSPECT BRAKE WARNING LIGHT
1. Inspect the parking brake warning light.
  1. Disconnect the connector from the parking brake switch.
