Checking wiring and connectors

Check the signal cable between upper electronic module (UEM) connector terminal #22 and mass movement sensor (MMS) connector terminal #3. Check for a short-circuit to ground. Check for an intermittent short-circuit to ground.

If no fault was found, try a new sensor.
