Description

INFOID:0000000001731152

The steering angle sensor is connected to the ABS actuator and electric unit (control unit) in addition to CAN
lines. CAN (Controller Area Network) is a serial communication line for real time application. It is an on-vehicle
multiplex communication line with high data communication speed and excellent error detection ability. Many
electronic control units are equipped onto a vehicle, and each control unit shares information and links with
other control units during operation (not independent). In CAN communication, control units are connected
with 2 communication lines (CAN H line, CAN L line) allowing a high rate of information transmission with less
wiring. Each control unit transmits/receives data but selectively reads required data only.

Diagnosis Procedure

INFOID:0000000001731154

INSPECTION PROCEDURE

1.

CHECK CONNECTOR

1.

Turn ignition switch OFF and disconnect ABS actuator and electric unit (control unit) connector E125,
check terminal for deformation, disconnection, looseness, and so on. If any malfunction is found, repair or
replace terminal.

2.

Reconnect connector and perform self-diagnosis.

Is above displayed on the self-diagnosis display?

YES
