Auto-On Headlight Sensor Inspection (If 
Equipped)

S6JB0A9206030

1) Disconnect negative (–) cable at battery.
2) Remove auto-on headlight sensor (1) located on the 

passenger side of the dashboard (2). Be careful not 
to damage the sensor (1) and dashboard by using 
rag (3).

3) Measure voltage between white wire terminal and 

black wire terminal at the following condition.
If measured voltage is out of specification, replace 
sensor.

Precautions

Precautions in Diagnosing Troubles for Combination Meter

S6JB0A9300001

Combination meter uses signals (information) from each control module by CAN communication to control 
speedometer, tachometer, fuel meter (petrol engine model), 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 light). 
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.

General Description

CAN Communication System Description

S6JB0A9301001

Refer to “CAN Communication System Description: For Petrol Engine Model in Section 1A” or “CAN Communication 
System Description: For Diesel Engine Model in Section 1A” for CAN communication system description. Combination 
meter communicates control data with each control module as follows.
