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.
Windscreen Wiper Function
The SCCM control unit records the 6 positions of the windscreen wiper stalk in digital form. This information is transmitted by the SCCM control unit to the UEC control unit via the LS CAN. The wiper stalk no longer engages mechanically; instead, it returns to its initial position even when the wipers are switched on. It is switched off by moving the lever in the opposite direction.
