CAUTION / NOTICE / HINT

NOTICE:

When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.


PROCEDURE

1.CHECK HARNESS AND CONNECTOR (CABIN OBJECT RECOGNITION CAMERA (MAP LIGHT ASSEMBLY) - BATTERY AND BODY GROUND)
a.

Disconnect the Q18 cabin object recognition camera (map light assembly) connector.


b.

Measure the voltage according to the value(s) in the table below.

Standard Voltage:
Tester Connection Condition Specified Condition

Click Location & Routing(Q18)Location & Routing

Click Connector(Q18)Body>Roof Wire>Cabin Object Recognition Sensor

Q18-2 (VCC+) - Body ground Drivers door open → close 11 to 14 V
