ERA CONTROL UNIT : DTC Logic"

.

Diagnosis Procedure

INFOID:0000000009721868

1.

ADJUST THE NEUTRAL POSITION OF THE STEERING ANGLE SENSOR

When U0428 is detected, adjust the neutral position of the steering angle sensor.

>> Perform adjustment of the neutral position of the steering angle sensor. Refer to 

BRC-9,

"ADJUSTMENT OF STEERING ANGLE SENSOR NEUTRAL POSITION : Special Repair
Requirement"

.

CAUTION:

For vehicles with VDC, adjust the steering angle sensor neutral position on the ABS actuator control
unit side.

AV CONTROL UNIT

AV CONTROL UNIT : Description

INFOID:0000000009721869

CAN (Controller Area Network) is a serial communication line for real-time application. It is an on-vehicle mul-
tiplex communication line with high data communication speed and excellent error detection ability. Many elec-
tronic control units are equipped onto a vehicle, and each control unit shares information and links with other
control units during operation (not independently). In CAN communication, control units are connected with 2
communication lines (CAN-H, CAN-L) allowing a high rate of information transmission with less wiring. Each
control unit transmits/receives data but selectively reads required data only.
