Height Sensor: Check

Prerequisites (unless otherwise specified):

• Breakout box connected.
• Sensor connected.
• Ignition switch position II.

Check 1 

Height sensor:

Measure the power supply for the height sensor in question. The value should be: U ≈ 5 V at ignition switch position II.

Check 2 

Height sensor:

Measure the voltage between signal and ground for the height sensor in question. The value should be U ≈ 2.5 V with the vehicle stationary.

The signal fluctuates around 2.5 V when vehicle height changes (increased/reduced load)
