U2156-87 Steering Angle Sensor

DTC Description

CAN COMMUNICATION

• CAN communication is a multiplex communication system. This enables the system to transmit and receive large quantities of data at high speed by connecting control units with 2 communication lines.

• CAN communication lines adopt twisted-pair line style (two lines twisted) for noise immunity. Refer to CAN Communication Signal Chart.

DTC DETECTION LOGIC

NOTE:

If “U2156-87” is detected, first diagnose the CAN communication system.

POSSIBLE CAUSE

CAN communication system

FAIL-SAFE

The following systems are canceled.

• Vehicle speed & vehicle-to-vehicle control function

• Lane keep function^*1

• Lane keep function^*2

• Lane change support function

• Overtaking support function

• Route driving support function

*1：ProPILOT Assist 2.1 display is green

*2：ProPILOT Assist 2.1 display is blue

NOTE:
