This is DTC which is related with communication error between PDM and other units.
? Body CAN communication Control Units : BCM(Body Control Module), CLU(Cluster), PDM(Power Distribution Module), SMK(Smart Key), SJB(Smart Junction Box).
*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 PDM by the serial communication line.
This code is outputted when power circuit is shorted to ground.
(During power supply from PDM to ESCL)
Item
Detecting Condition
Possible Cause
DTC Strategy
ESCL power output line check
(by voltage monitoring)
Short to ground in ESCL power circuit
Enable Conditions
Under power supply from PDM to ESCL
Threshold Value
ESCL power circuit is shorted to ground(2V and below)
Diagnostic Time
Immediately
DTC Erasing Time
DTC is erased immediately after trouble fixed. (Under power supply from PDM to ESCL state)
