an incorrect diagnostic trouble code may be
set. Prior to this diagnosis, diagnose the CAN
bus lines.

• Whenever the ECU is replaced, ensure that

the CAN bus lines are normal.

OPERATION

AWC-ECU receives the signal of the ignition switch
from ETACS-ECU via CAN communication.

DIAGNOSTIC TROUBLE CODE SET
CONDITIONS

This diagnostic trouble code is set when the cranking
signal is continued for the specified time during driv-
ing.

PROBABLE CAUSES

• Malfunction of the ETACS-ECU

• Ignition switch malfunction

• Damaged harness wires and connectors
