   NOTICE:

   Tire wear and excessively high or low tire pressure affect speedometer indications.

2. Check the deflection of the speedometer indicator.
   

   Reference:

   Below 0.3 mph (0.5 km/h)
   

Check the output signal waveform.

1. Remove the combination meter assembly, but do not disconnect the connector.
   

2. Connect an oscilloscope to terminals D1-16 and to the body ground.
   

3. Start the engine.
   

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

   Item	Contents
   Terminal Connection	+S (D1-16) and Body Ground
   Tool Setting	5 V/DIV, 20 ms/DIV
   Condition	Driving at approximately 12mph (20km / h)

   OK:

   As shown in the illustration.
   

   NOTICE:

   Waveform is indicated as the vehicle speed increases, the cycle of the signal waveform narrows.

5. Reinstall the combination meter assembly.
   

Check the operation.

1. Connect the Techstream to the DLC3.
   

2. Turn the ignition switch ON and turn the tester ON.
   

3. Select the item below from the Data List and read the value displayed on the Techstream.
   
   

   Body Electrical / Combination Meter / Data List:

   Tester Display	Measurement Item/Range	Normal Condition	Diagnostic Note
   Engine Rpm	Engine speed/Min.: 0 rpm, Max.:12,750 rpm	Approximately same as actual engine speed (When engine is running)	-

4. Compare the engine speed displayed on the tester with the tachometer reading.
   

   Reference:

   Standard Indication (r/min)	Acceptable Range [Data in ( ) are for reference]
   700 r/min	630 to 770 r/min
   1,000 r/min	(900 to 1,100 r/min)
   2,000 r/min	(1,850 to 2,150 r/min)
   3,000 r/min	2,800 to 3,200 r/min
   4,000 r/min	(3,800 to 4,200 r/min)
   5,000 r/min	4,800 to 5,200 r/min
   6,000 r/min	(5,750 to 6,250 r/min)
   7,000 r/min	(6,700 to 7,300 r/min)

Disconnect the J5 fuel sender gauge connector.

Check the fuel receiver gauge operation when the ignition switch is turned to the ON position.

OK:

No. 1 segment flashes.

Connect terminals 2 and 3 on the wire harness side connector of the fuel sender gauge.

Check the fuel receiver gauge operation when the ignition switch is turned from OFF to ON.

OK:

All segments, from No. 1 to No. 8, illuminate.

Reconnect the fuel sender gauge connector.

Turn the ignition switch to the ON position, and check that the receiver gauge No. 1 segment flashes when the fuel volume is less than 6.3 liters (less than 15 % of the total fuel tank capacity).

OK:

Fuel Volume	Flashing Speed (Interval)
1.6 gal (6.3 liters) (Less than 15 % of total fuel tank capacity)	Flashes slowly (1.2 seconds)
1.1 gal (4.2 liters) (Less than 10 % of total fuel tank capacity)	Flashes quickly (0.6 seconds)

Disconnect the engine oil pressure switch connector.

Turn the ignition switch to the ON position.

Ground the terminal of the wire harness side connector, then check the engine oil pressure warning light.

OK:

Engine oil pressure warning light illuminates.

Reconnect the engine oil pressure switch connector.

Inspect the parking brake warning light.

1. Disconnect the parking brake switch connector.
   

2. Turn the ignition switch to the ON position.
   

3. Ground the terminal of the wire harness side connector, then check the parking brake warning light.
   

   OK:

   Brake warning light illuminates.
   

4. Reconnect the parking brake switch connector.
   

Inspect the brake fluid level warning light.

1. Disconnect the brake fluid level warning switch connector.
   

2. Turn the ignition switch to the ON 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 illuminates.
   

4. Reconnect the brake fluid level warning switch connector.
   

Remove the reservoir tank cap and strainer.

Disconnect the brake fluid level warning switch connector.

Measure the resistance between the terminals.

Standard resistance:

Float inside reservoir tank is in high position (switch OFF): 10 k Ω or higher

Use a siphon or a similar tool to drain fluid out of the reservoir tank.

Measure the resistance between the terminals.

Standard resistance:

Float inside reservoir tank is in low position (switch ON): Below 1 Ω

Pour the fluid back into the reservoir tank.

Reconnect the brake fluid level warning switch connector.

Reinstall the reservoir tank cap and strainer.

Disconnect the connector from the washer level warning switch.

Turn the ignition switch to the ON position.

Ground the terminal of the wire harness side connector, then check the washer level warning light.

Turn the ignition switch to the ON position.

Connect a terminal to the other terminal of the wire harness side connector, then check the engine coolant temperature warning light.

OK:

Engine coolant temperature warning light illuminates.

Reconnect the engine coolant temperature sensor connector.

NOTICE:

DTCs may have been set. Check for DTCs and clear any that have been set.
