Precautions in Diagnosing Troubles for Combination Meter
S5JB0A9300001
• Combination meter uses signals (information) from each control module by CAN communication to control
speedometer, tachometer, fuel meter, engine coolant temp meter, warning light and indicator light (other than air
bag warning light, headlight leveling warning light, rear fog light and turn signal indicator lamp). Therefore, check
that no DTC is detected in each module before performing combination meter symptom diagnosis. If any DTC is
detected, correct trouble indicated by that DTC troubleshooting first.
• Seat belt reminder can be canceled by scan tool or specified procedure. If neither warning buzzer nor seat belt
reminder light operates, first confirm that seat belt reminder is not selected referring to “Scan Tool Data: in Section
10B”. For further details, refer to “Seat Belt Construction: in Section 8A”.
