TACHOMETER : System Description

INFOID:0000000009174226

The crank position sensor sends a crankshaft position signal to the ECM. The ECM provides an engine speed

signal to the combination meter via CAN communication lines. The tachometer indicates engine speed in rev-

olutions per minute (rpm).

ENGINE COOLANT TEMPERATURE GAUGE

ENGINE COOLANT TEMPERATURE GAUGE : System Description

INFOID:0000000009174228

The engine coolant temperature sensor sends an engine coolant temperature signal to the ECM. The ECM

provides an engine coolant temperature signal to the combination meter via CAN communication lines. The

engine coolant temperature gauge indicates the engine coolant temperature. 

FUEL GAUGE

ENGINE-START EFFECT FUNCTION

When recognizing an engine start, the combination meter controls the following items for producing the effect:

• Speedometer

• Tachometer

• Engine coolant temperature gauge

• Fuel gauge

• Meter illumination

Meter and Illumination Operations During Engine-start Effect

The combination meter controls the following items during the engine-start effect.

NOTE:

The pointers are stopped and illumination is turned off while cranking the engine.

Engine Start Judgement

The combination meter judges “engine-start” and activates the engine-start effect only once when the follow-

ing operational conditions are all satisfied.

NOTE:

INFOID:0000000009174237

INFORMATION DISPLAY : System Description

INFOID:0000000009174238

FUNCTION

The information display can indicate the following items:

• Outside air temperature

• Trip computer

• Intelligent Key operation information

• CVT shift position indicator

• Odometer

• Warning/Indication messages (door open, liftgate open, low oil pressure, CVT, 4WD, I-Key, low fuel, low

washer fluid, release parking brake, low tire pressure and loose fuel cap).

OUTSIDE AIR TEMPERATURE INDICATION

The ambient temperature sensor sends the ambient sensor signal to the A/C auto amp. The a/c auto amp,

then sends the signal to the combination meter via CAN communication lines.
