This is DTC which is related with communication error between PDM and other units.
※ Body CAN communication Control Units : IPM(Intelligent integrated Platform Module), CLU(Cluster), PDM(Power Distribution Module), SMK(Smart Key), RPAS(Rear Parking Assist System).
※ LIN communication Control Units : IPM(Intelligent integrated Platform Module), DDM(Drive Door Module), ADM(Assist Door Module), IMS(Integrated Memory System-PSM.
*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.)
This code is outputted when power circuit is shorted to battery.
(During no power supply from PDM to ESCL)
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
ESCL power output line check (by voltage monitoring) |
•
Short to power in ESCL power circuit |
Enable Conditions |
•
No power supply from PDM to ESCL | |
Threshold Value |
•
ESCL power circuit is shorted to power (7V and above) | |
Diagnostic Time |
•
Immediately | |
DTC Erasing Time |
•
DTC is erased immediately after trouble fixed. (Under no power supply from PDM to ESCL state) |
