Precautions
Precautions in Diagnosing Troubles for Combination MeterS7RS0B9300001
Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, engine coolant temp meter, warning light and indicator light (other than air bag warning
light, high beam indicator light, EPS warn ing light and turn signal indicator light). Therefore, check that no DTC is
detected in each module before performing combination me ter symptom diagnosis. If any DTC is detected, correct
trouble indicated by that DTC troubleshooting first.
General Description
CAN Communication System DescriptionS7RS0B9301001
Refer to “CAN Communication System Description in Section 1A” for Can communication system description.
Combination meter communicates control data with each control module as follows.

Information Display Symptom Diagnosis (If Equipped)S7RS0B9304015
NOTE
This thermometer indicates the ambient temperature in back of front bumper member. Under any one
of the following listed conditions, however, even when the ambient temperature goes up, the
thermometer display does not rise so as to correct the rise of the ambient temperature caused by the
radiant heat of the engine. When the ambient temperature drops, the thermometer reading follows the
change in the temperature.
Be sure to bear this in mind when diagnosing trouble.
• The vehicle speed is 30 km/h (18 mph) or lower.
• Vehicle speed signal is faulty.
• The ignition switch is turned on again within 2 hours.
