PROCEDURE

1.CHECK HARNESS AND CONNECTOR (INNER REAR VIEW MIRROR ASSEMBLY - REAR INNER MIRROR CAMERA ASSEMBLY)

Disconnect the Q12 inner rear view mirror assembly connector.

Disconnect the T18 rear inner mirror camera assembly connector.

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

Standard Resistance:

Q12-4 (CEV+) - T18-4 (CEV+)	Always	Below 1 Ω
Q12-3 (CEV-) - T18-2 (CEV-)	Always	Below 1 Ω
Q12-5 (SGND) - T18-5 (SGND)	Always	Below 1 Ω
Q12-1 (CEG) or T18-3 (CEG) - Body ground	Always	10 kΩ or higher
Q12-2 (CEB+) or T18-1 (CEB+) - Body ground	Always	10 kΩ or higher
Q12-4 (CEV+) or T18-4 (CEV+) - Body ground	Always	10 kΩ or higher
Q12-3 (CEV-) or T18-2 (CEV-) - Body ground	Always	10 kΩ or higher
