When Monitored

RDM SYSTEM ENABLING CONDITIONS AND FAULT SETTING CRITERIA:

The position sensor faults have these shared Monitoring Conditions:

With the ignition on for 15 seconds or longer.

Additional Monitoring Conditions for motor performance faults:

The actuator motor is being commanded to operate.

FAULT SETTING CRITERIA
(C2100-13/14/15, C2120-13/14/15) - Actuator Motor circuit faults C2100-13/14/15 - RDM actuator motor C2120-13/14/15 - PTU actuator motor	The DTCM detects an open or short circuit condition in the circuitry for one of the actuator motors.
(C2160-04, C2200-04) - Power Stage faults (C2160-04) - RDM Power Stage fault (C2200-04) - PTU Power Stage fault	The DTCM detects a failure during the Power Stage self test diagnostics.
(C2250-78) - RDM motor performance fault	The DTCM detects that the RDM clutch backlash is too high during operation.
(C2080-64, C2280-92) - motor current implausible faults C2080-64 - RDM actuator motor C2280-92 - PTU actuator motor	The DTCM detects that the actuator motor current is not plausible compared to the expected current draw during operation.
(C2210-92, C2270-77) - motor performance faults C2210-92 - RDM actuator motor C2270-77 - PTU actuator motor	The DTCM detects that the actuator motor is not in the commanded position or is rotating in the opposite direction
(C2240-92, C2290-92) - motor free spinning faults C2240-92 - RDM actuator motor C2290-92 - PTU actuator motor	The DTCM detects that the actuator motor is in a free spinning condition
(C2300-00) - RDM Classification	The RDM classification value has not been learned in the DTCM
PTU and RDM Power Stage/Actuator overtemp faults (RDM - C2100-98, PTU - C2170-98) (RDM - C2150-98, PTU - C2180-98) (RDM - C221D-98, PTU - C2190-98) (RDM - C2230-98)	The DTCM detects an over temperature condition in the actuator Power Stage circuit. There are 3 severity levels of overtemp faults for the PTU and RDM actuators. (RDM - C2100-98, PTU - C2170-98) - Power Stage has reached the overtemp warning threshold. (RDM - C2150-98, PTU - C2180-98) - Power Stage has reached the overtemp deactivation threshold. Power Stage switched off. (RDM - C221D-98, PTU - C2190-98) - Power Stage has reached the overtemp deactivation threshold several times during the ignition cycle. Power Stage switched off permanently. (RDM - C2230-98) - RDM Clutch temperature is above 200°C or actuator temperature is above 160°C

POSSIBLE CAUSES - MOTOR CIRCUIT FAULTS
ACTUATOR MOTOR CONTROL CIRCUIT SHORTED TO VOLTAGE (CIRCUIT FAULTS)
ACTUATOR MOTOR CONTROL SHORTED TO GROUND (CIRCUIT FAULTS)
ACTUATOR MOTOR CONTROL CIRCUIT OPEN/HIGH RESISTANCE (CIRCUIT FAULTS)
FAULTY 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 - MOTOR PERFORMANCE FAULTS
RDM CLASSIFICATION VALUE NOT LEARNED IN THE DTCM
DAMAGED INTERNAL PTU OR RDM ASSEMBLY HARDWARE COMPONENTS (MOTOR PERFORMANCE AND FREE SPINNING FAULTS)
FAULTY ACTUATOR MOTOR - DAMAGED ACTUATOR MOTOR SHAFT OR GEAR (MOTOR PERFORMANCE AND FREE SPINNING FAULTS) (The RDM motor should not be replaced separately. Replace the RDM assembly if the motor is faulty)
FAULTY DRIVETRAIN CONTROL MODULE (DTCM)

POSSIBLE CAUSES - OVERTEMP FAULTS
SYSTEM BEING OVERWORKED - DRIVEN AGGRESSIVELY
FLUID LEVEL LOW - EXCESSIVE FRICTION CAUSING OVERHEAT
PTU NOT ENGAGING PROPERLY - ACTUATOR OVERWORKING
RDM CLUTCH FRICTION PLATES SLIPPING CAUSING OVERHEAT
FAULTY ACTUATOR MOTOR (The RDM motor should not be replaced separately. Replace the RDM assembly if the motor is faulty)
FAULTY DRIVETRAIN CONTROL MODULE (DTCM)
