BRAKE SYSTEM
DTC C1623 CAN TIME-OUT STEERING ANGLE SENSOR
COMPONENT LOCATION
E13058C2
Refer to DTC C1235.
GENERAL DESCRIPTION
EABBA871
The Steering angle sensor(SAS) is joined to the multi function switch and uses a CAN communication. The SAS is used to
determine turning direction and speed of the steering wheel. The HECU uses the signals from the SAS when performing
ESP-related calculations.
DTC DESCRIPTION
E2768D2E
The HECU checks the CAN communcation lines for normal ESP control, and sets this code if a sAS message is not
received within predefined time.
DTC DETECTING CONDITION
E7C4B0FD
Item
Detecting Condition
Possible cause
DTC Strategy
• CAN massage monitoring
Monitoring
Period
• Continuous
Enable
Conditions
• Faults are detected if SAS message was not received
on time by the CAN controller of HECU.
Fail Safe
• Inhibit the ESP control and ABS/EBD control is available.
Meanwhile, stop checking the ESP switch failure
under the ESP control.
• Inoperative SAS
• Inoperative HECU
• Open circuit in SAS line
