53.(00110011) Phase 2 to 5 - Rotor Position Sensor Fault

The Motor Controller has attempted a motor step test and has found that the motor has not stepped to the correct position. It has detected that the motor is connected and that the Motor Controller drive is operational. The Rotor Position Sensor signal sensing system is at fault.

Primary Source - Wiring

Action - Check the Rotor Position Sensor harness for continuity and that the connectors are correctly applied to the Rotor Position Sensor and to the Motor Controller.

Secondary Source - Rotor Position Sensor

Action - Check Rotor Position Sensor with RPS Tester or Replace Rotor Position Sensor.

Tertiary Source - Motor Controller

Action - The Motor Controller motor sensing circuitry may be faulty. Replace Motor Controller.

54.(00110110) Phase 2 to 5 - Motor / Motor Control Step Fail

The Motor Controller has attempted a motor step test and has found that the motor has not stepped to the correct position. The Motor Controller has detected that there is no motor current. This indicates that either the motor is not connected or the Motor Controller motor drive is faulty.

Primary Source - Wiring

Action - Check the continuity of the motor harness and that the connectors are correctly applied to the stator and to the Motor Controller.

Secondary Source - Motor

Action - Check resistance of motor phases. Check the brass bridge terminal on the stator is not open circuit or burnt. Otherwise replace stator.

Tertiary Source - Motor Controller Action - Replace Motor Controller.

55.(00110111) Phase 3 to 5 - System Step Fail

Primary Source - Rotor Position Sensor

Action

1.Check Motor & Rotor Position Sensor wiring

2.Check Rotor Position Sensor with RPS tester
