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.
LEDS In Doors For Lock Indication
Usually there are locking buttons in the doors, but the C70 does not have these. The vehicle is equipped with LEDs instead that indicate whether the vehicle is locked or not. The LEDs light for approximately 5 minutes after locking the vehicle. The LEDs are on each door and are directly connected to the Central electronic module (CEM).
There are diagnostics for the LEDs.
