Possible causes of fault
- 'Open circuit/short circuit to B+': short circuit to B+ (12 V) in the voltage supply (5 V)/ground supply wiring
- 'Open circuit/short circuit to B+': open circuit in the voltage supply (5 V)/ground supply wiring
- 'Short circuit to ground': short circuit to ground in the voltage supply (5 V)/ground supply wiring
- 'Above upper limit': short circuit to B+ (12 V) in the voltage supply (5 V) wiring
- 'Above upper limit', servo motor temperature sensor faulty
