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
