On-Vehicle inspection

METER: METER / GAUGE SYSTEM: ON-VEHICLE INSPECTION

1. INSPECT SPEEDOMETER

(a) Check speedometer operation.

NOTICE:
* The combination meter assembly receives the vehicle speed signal from the skid control ECU direct line. Therefore, perform the following inspection referring to values on the Data List of the skid control ECU because it is the source of the vehicle speed signal.
* The Data List values of the skid control ECU are used for this inspection. Therefore, make sure to perform the inspection after confirming that no DTCs are output from the brake control system.
* If the tire size or tire pressure is not within the specified range, or the tires are excessively worn, the speedometer indication error will increase. Therefore, make sure to perform the inspection after checking that the tire size, tire pressure and tire wear are in the specified range.

(1) Before starting the following inspection, check if the Brake Control System outputs the DTCs.

(2) Check the values by referring to the table below.

ABS/VSC/TRAC:





Reference: mph (for U.S.A.)





Reference: km/h (except U.S.A.)





NOTICE:
Tire wear, as well as over or under inflation will cause errors.

2. INSPECT TACHOMETER

(a) Check operation

(1) Connect Techstream and start the engine.

(2) Compare the test results with the tachometer 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 ignition 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 ignition 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 ignition switch on (IG), then check that the fuel level needle indicates EMPTY and the fuel level warning light comes on.

OK:

Fuel level warning light comes on.

5. INSPECT LOW ENGINE OIL PRESSURE WARNING LIGHT

(a) Disconnect the connector from the low oil pressure switch.

(b) Turn the ignition switch on (IG).

(c) Ground the terminal of the wire harness side connector, then check the low oil pressure warning light.

OK:

Low engine oil pressure warning light comes on.

6. INSPECT BRAKE WARNING LIGHT

(a) Inspect the parking brake warning light.

(1) Disconnect the connector from the parking brake switch.

(2) Turn the ignition 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 ignition 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.

7. 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.

Resistance:

Float up (switch off): 1.9 to 2.1 kOhms

(d) Use a syphon, etc. to take fluid out of the reservoir tank.

(e) Measure the resistance between the terminals.

Resistance:

Float down (switch on): Below 1 Ohms

(f) Pour the fluid back in the reservoir tank.
