Component Tests and General Diagnostics
METER: METER / GAUGE SYSTEM: ON-VEHICLE INSPECTION
1. INSPECT SPEEDOMETER
(a) Inspect the speedometer.
(1) 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 models for U.S.A.)
Reference:
mph (U.S.A)
NOTICE:
Do not use worn, underinflated or overinflated tires, as the speedometer reading will be inaccurate.
(2) Check the deflection width of the speedometer indicator.
Reference:
Below 0.5km/h (0.3 mph)
2. INSPECT TACHOMETER
(a) Inspect the tachometer.
(1) Connect the tune-up test tachometer and start the engine.
NOTICE:
* 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.
(2) Compare the result of the test with the standard indication.
* DC 13.5 V, at 25°C (77°F)
Reference:
3. INSPECT FUEL RECEIVER GAUGE
(a) Disconnect the connector from the sender gauge.
(b) Turn the engine switch on (IG), then check the position of the receiver gauge needle.
OK:
Needle position is on EMPTY
(c) Connect terminals 2 and 3 on the wire harness side connector of the fuel sender gauge.
(d) Turn the engine switch on (IG), then check the position of the receiver gauge needle.
OK:
Needle position is on FULL
4. INSPECT FUEL LEVEL WARNING LIGHT
(a) Disconnect the connector from the sender gauge.
(b) Turn the engine switch on (IG), then check that the fuel level needle indicates EMPTY and the fuel level warning light comes on.
OK:
Fuel level needle indicates EMPTY and warning light comes on.
5. INSPECT BRAKE WARNING LIGHT
(a) Inspect the parking brake warning light.
(1) Disconnect the connector from the parking brake switch.
(2) Turn the engine switch on (IG).
(3) Ground the terminal of the wire harness side connector, then check the parking brake warning light.
OK:
Brake warning light comes on.
(b) Inspect the brake fluid level warning light.
(1) Disconnect the connector from the brake fluid level warning switch.
(2) Turn the engine switch on (IG).
(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.
6. INSPECT BRAKE FLUID LEVEL WARNING SWITCH
(a) Remove the reservoir tank cap and strainer.
(b) Disconnect the connector.
(c) Measure the resistance between the terminals.
Standard:
Float up (switch off): 10 kOhms or higher
(d) Use a siphon, etc. to take fluid out of the reservoir tank.
(e) Measure the resistance between the terminals.
Standard:
Float down (switch on): Below 1 Ohms
(f) Pour the fluid back in the reservoir tank.
7. INSPECT WASHER FLUID LEVEL WARNING SWITCH
(a) Disconnect the connector from the washer level warning switch.
(b) Turn the engine switch on (IG).
(c) Ground the terminal of the wire harness side connector, then check the washer level warning light.
OK:
Washer level warning light comes on.
8. INSPECT MULTI-INFORMATION DISPLAY
(a) Dot display inspection mode
HINT
* Dot display inspection mode can be exited by turning the engine switch from on (IG) to off.
* Dot display inspection mode can be performed using the Techstream's Active Test Scan Tool Testing and Procedures
(1) With the engine switch off, turn the engine switch on (IG) while pressing the steering pad switch's DISP switch.
(2) All of the multi-display's dots will illuminate.
(3) When all of the dots are illuminated, check that the display is not damaged.
