Checking input signal

Read off the value for Hall sensor 3.

The value should not change when the seat is not affected.

HINT: If the value counts up or down there may be a fault in the sensor, an intermittent short-circuit to supply voltage or an internal fault in the power seat module (PSM). 

Remedy as necessary.
