Safety Warning
DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.
AV Tail Output Control
- In ACC, IGN, START terminal states, monitoring of the auto light sensor supply's range (AutoLightPwr) is performed and a failure is raises up (Auto Light failure) when the supply's voltage is out of range (outside of range (4V :6V)).
If Auto Light failure occurs and as long as this error is present, the tail lamp and head lamp low must be turned on regardless of the sunlight level provided by the sensor.
When physical Auto light sensor failure occurs the Lamps are turned on, because a zero voltage level is provided by the sensor when internal failure is present.
This is designed to prevent any head lamp cut off when the failure occurs during the night.
AV Tail Output Control is started In ACC, IGN, START regardless of MFSW Auto Light switch.
CAN signal AV_Tail is set/reset at the same time as AV Tail.
