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.
Load shut-down, Terminal 50
Car Access System 4 sends the "terminal 50 ON" status. The signal is received by the footwell module and junction box electronics via K-CAN.
The junction box electronics and the footwell module prevent operation of the power windows during the start procedure or interrupt current operation of the power windows. This protects the battery during the starting procedure.
The power window switches must be pressed again following an interruption in operation.
Operation of the power windows is not possible until the start procedure has been completed.
