GENERAL DESCRIPTION
Steering angle sensor is a hall plate between the photo-controller LED and the photo transistor. As the hole plate rotates with steering wheel rotation, electrical signal will be generated depending on whether the LED light passes through the plate to the photo-transistor or not. The signal is the steering wheel operation angular velocity and used to detect the steering wheel turning direction.
DTC DESCRIPTION
The DTC will set when the steering angle sensor #1 signal to 4WD ECM is out of range.
Refer to DTC P1717 .
The DTC will set when the steering angle sensor #2 signal to 4WD ECM is out of range.
Steering angle sensor is a hall plate between the photo-controller LED and the photo transistor.
As the hole plate rotates with steering wheel rotation, electrical signal will be generated depending on whether the LED light passes through the plate to the photo-transistor or not.
The signal is the steering wheel operation angular velocity and used to detect the steering wheel turning direction.
Steering angle center signal is for detecting if the steering wheel is at center or rotates.
The DTC will set when the steering angle sensor center signal to 4WD ECM is out of range.
As a standard of judgement about a driver's acceleration degree, TPS signal is used on 2.0L gasoline engines or 2.7L gasoline engines. On both occasions, the signals are inputted to 4WD ECM from ECM (PCM: 2.0L gasoline engine) through CAN.
This signal is used as a standard signal which decides torque distribution together with a steering angle sensor signal, a wheel speed sensor signal and a brake signal.
The DTC will set when there is no TPS signal or the signal is out of range.
4WD ECM control EMC (Electric Magnet Clutch) by current and EMC distributes torque properly by using slip of multiclutch.
As related with EMC, this trouble code will set in case EMC output harness is open or shorted to battery.
Refer to DTC P1728 .
Refer to DTC P1728 .
When the tone wheel rotates adjacent to the sensor pole piece, an alternating current signal is generated in the coil with a frequency proportionate to the wheel speed.
This signal which is generated from the wheel speed sensor is inputted to the 4WD ECM.
The DTC will set when there is no wheel speed sensor signal.

A communication line exists between the Engine Control Module (ECM) and the Transaxle Control Module (TCM). The communication is through a Control Area Network (CAN). Without CAN communication, an independent pin and wiring is needed to receive a sensor information from a ECM. The more information to be communicated, the more wiring is required. In case of CAN communication type, all the information needs to be communicated among control modules such as ECM and TCM using CAN lines.
After clearing the DTC, check the malfunction of TCM and 4WD ECM, if the DTC sets again. This code may set if there is no signal to 4WD ECM.
Without TCS (Traction Control System), 4WD ECM receives the signal directly from the wheel speed sensors. With TCS, 4WD ECM receives the signal through CAN communication line from TCS module which gets the wheel speed sensor signal from the sensors.
This DTC is about TCS module - ECM Communication Line and will set when there are no signals from the wheel speed sensors to 4WD ECM.
