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), Alarm Control Siren Assy.
*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.)
LIN Communication is that IPM send massage to Alarm Control Siren Assy wait for massage from IPM. If that modules have not received the massage in specific time then become LIMPHOME MODE.
This code is set when LIN commumication error that LIN commumication harness is circuit open or short or all kinds of nosie detected.
Item | Detecting Condition | Possible Cause |
DTC Strategy |
•
Monitoring SERIAL communication status |
•
Check LIN line circuit open. |
Enable Conditions |
•
Ignition "ON"
•
Engine ON
•
During LIN Communication | |
Threshold Value |
•
IPM have not received any Header from Lin master over 10 sec | |
Diagnostic Time |
•
If fault is happened then Detected immediately/After fault is disappear, memoried historic code. | |
DTC Erasing Time |
•
Present error is cleared by repair a fault/ Historic error is after DTC clear by Scantool |
