Sunload Sensor

WARNING: This page is about a different car, the 2003 Infiniti I35. However, it is still accessible from the selected car via links, so may be relevant.

Measure voltage between auto amplifier terminal 12 and ground. If NG, replace sunload sensor.

When checking sunload sensor, select a place where sun shines directly on it.
