Hall Effect ShortShort circuit in a jack position-sensor circuit
The controller detected a short in one of the Hall-effect feedback circuits.
What it means
Plain-English answer
Hall-effect feedback tells the controller how the jacks are moving. A short can make position feedback unreliable and requires circuit testing.
