When Monitored

RDM SYSTEM ENABLING CONDITIONS AND FAULT SETTING CRITERIA: 

The position sensor faults have these shared Monitoring Conditions: 

FAULT SETTING CRITERIA
Hall sensor supply circuit fault (C2050-1C)  The DTCM detects that the PTU or RDM hall effect position sensor supply circuit voltage is out of range low/high.
(C2060-09, C2070-09) - Position sensor circuit faults 
  • C2060-09 - RDM position sensor
  • C2070-09 - PTU position sensor
 The DTCM detects that one of the actuator motor hall effect position sensor voltage signals is out of range low/high.
NOTE:

The DTCM does not set an individual low or high fault for the two internal position sensors. If either position signal for the actuator motor is low or high the sensor component failure fault will set.
(C2080-09, C2090-09) - Temperature sensor signal out of range fault 
  • C2080-09 - RDM temp sensor
  • C2090-09 - PTU temp sensor
 The DTCM detects that the actuator motor internal temp sensor voltage signal is out of range low/high.
NOTE:

The DTCM does not set an individual low or high fault for the internal temp sensors. If the internal temp sensor signal is low or high the sensor component failure fault will set.
POSSIBLE CAUSES - POSITION SENSOR FAULTS
HALL POSITION SENSOR SUPPLY VOLTAGE CIRCUIT OPEN OR SHORTED TO GROUND (HALL SENSOR SUPPLY VOLTAGE FAULT)
POSITION SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE (POSITION SENSOR CIRCUIT FAULT)
POSITION SENSOR SIGNAL CIRCUIT SHORTED TO GROUND (POSITION SENSOR CIRCUIT FAULT)
POSITION SENSOR SIGNAL CIRCUIT OPEN/HIGH RESISTANCE (POSITION SENSOR CIRCUIT FAULT)
SENSOR RETURN CIRCUIT OPEN/HIGH RESISTANCE
FAULTY POSITION SENSOR (INTERNAL TO THE ACTUATOR MOTOR) (The RDM motor should not be replaced separately. Replace the RDM assembly if the motor is faulty)
FAULTY DRIVETRAIN CONTROL MODULE (DTCM)
POSSIBLE CAUSES - TEMPERATURE SENSOR FAULTS
POSITION SENSOR SIGNAL CIRCUIT SHORTED TO VOLTAGE
POSITION SENSOR SIGNAL CIRCUIT SHORTED TO GROUND
POSITION SENSOR SIGNAL CIRCUIT OPEN/HIGH RESISTANCE
SENSOR RETURN CIRCUIT OPEN/HIGH RESISTANCE
FAULTY TEMPERATURE SENSOR (INTERNAL TO THE ACTUATOR MOTOR) (The RDM motor should not be replaced separately. Replace the RDM assembly if the motor is faulty)
FAULTY DRIVETRAIN CONTROL MODULE (DTCM)
