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.
