On-Vehicle Inspection

1. Using a speedometer tester, inspect the speedometer and confirm that the speedometer readings are within the acceptable range. Also check the odometer operation.

   Reference: mph 

   SPEEDOMETER REFERENCE
   
   

   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, underinflated or overinflated tires, as the speedometer reading will be inaccurate.
2. Check the deflection width of the speedometer indicator.

   Reference: 

   Below 0.3 mph (0.5 km/h) 

1. Remove the combination meter, but do not disconnect the connector.
2. Start the engine.
3. Check the signal waveform according to the condition(s) in the table below
   SIGNAL WAVEFORM REFERENCE
   
   

   Item	Condition
   Terminal connection	C37-20 (+S) - Body ground
   Tool setting	5 V/DIV, 20 msec/DIV
   Vehicle condition	Driving at approx 12 4 mph (20 km/h)

   OK: 

   Waveform is as shown in  Fig 1 . 

   HINT:

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

1. Connect an intelligent tester or a Techstream to the DLC3.
2. Start the engine.
3. Operate the intelligent tester or Techstream according to the display and select "DATA LIST" or "Data List" (See DATA LIST / ACTIVE TEST  )

   Intelligent tester: Body / Combination Meter / DATA LIST 

   BODY / COMBINATION METER / DATA LIST
   
   

   Item	Measurement Item/ Range	Normal Condition	Diagnostic Note
   TACHO METER	Engine speed Min.: 0 Max.: 12,750	Approximately same as actual engine speed	Unit: rpm

   Techstream: Body Electrical / Combination Meter / Data List

   Item	Measurement Item/ Range	Normal Condition	Diagnostic Note
   Engine RPM	Engine speed Min.: 0 Max.: 12,750	Approximately same as actual engine speed	Unit: rpm

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

   Reference

OK: 

Needle position is on EMPTY. 

OK: 

Needle position is on FULL. 

OK: 

Fuel level warning light comes on. 

1. Disconnect the parking brake switch connector.
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 illuminates. 

4. Reconnect the parking brake switch connector.

1. Disconnect the brake fluid level warning switch connector.
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 light.

   OK: 

   Brake warning light illuminates. 

4. Reconnect the brake fluid level warning switch connector.

HINT:

A float is located inside the reservoir. Its position can be changed by increasing or decreasing the level of brake fluid.

Standard resistance 

HINT:

If there is no problem after finishing the above check, adjust the brake fluid level to the MAX level.

OK: 

Engine oil pressure warning light illuminates. 

HINT:

If the reset fails, the MAINT REQD indicator light remains illuminated. Perform the procedure again.
