This is DTC which is related with communication error between SMK and other units.
※ Body CAN communication Control Units : BCM(Body Control Module), CLU(Cluster), , SMK(Smart Key),SJB(Smart Junction Box), PSM(Power Seat Module).
*¹ CAN (Controller Area Network) : CAN is serial bus communication type which links not only communication system but also control units each other.
*² LIN (Local Interconnect Network) : LIN is serial communication type which is used in electrical control system.(This is less expensive.)
The steering wheel lock/unlock state of ESCL and the required data when EMS(Engine Management System) controls starting are sent to SMK Module by the serial communication line.
This code is outputted when power circuit is shorted to battery.
(During no power supply from SMK Module to ESCL)
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
ESCL power output line check (by voltage monitoring) | 1. Short to power in ESCL power circuit |
Enable Conditions |
•
No power supply from Smartkey Module to ESCL | |
Threshold Value |
•
ESCL power circuit is shorted to power (7V and above) | |
Diagnostic Time |
•
Immediately |
