Component Location
General Description

Steering angle sensor is a hole plate between the photo-controller LED and the photo transistor. As the hole plate rotates during steering wheel rotation, an electrical signal will be generated depending on whether the LED light passes through the plate to the photo-transistor or not. This signal which is a angle velocity of steering wheel is made use of sensing the rotating direction & neutrality of steering wheel. In case ABS(ESP) system is applied to the vehicle steering angle sensor signal is sent to 4WD-ECM(TCCU) by CAN communication.

DTC Description

This failure code is related to the Steering angle sensor #2 and is set if input signal to TCCU is "Loss of signal out of range".

This failure code is related to the TCCU communication line of the ESP(ABS CONTROL MODULE) application system and is set if input signal to TCCU is in"Loss of signal out of range".
