Component Specification: Switch: Check

Check 1 

Switch:

Measure the power supply. The value should be U ≈ 5 V at ignition switch position II.

Check 2 

Switch:

Measure the voltage between signal and ground for the switch. The value should be U = 1.559 - 4.322 V depending on the driving program selected with the switch.

Comfort driving program. U = 1.559 - 2.050 V

Sport driving program. U = 2.554 - 2.916 V

Advanced driving program. U = 3.349 - 3.632 V

Switch not actuated: U = 4.110 - 4.322 V
