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.

NOTE
Confirm that fuel meter is in good condition before referring to the following possible causes.
• When fuel level sensor circuit is open or short, fuel meter indicates empty even if fuel tank does not empty.
• The low fuel warning light comes ON when fu el level is lower than specification below.

Low fuel warning light operation:
ConditionPossible cause Correction / Reference Item
Engine coolant
temperature (ECT) meter
