Scheme 28
- CAN (Controller Area Network): CAN is serial bus communication type which links not only communication system but also control units each other.
- LIN (Local Interconnect Network): LIN is serial communication type which is used in electrical control system. (This is less expensive.)
This is DTC which is related with communication error between IPM and other units.
(*Control Units: IPM (Inter Panel Module), FAM (Front Area Module), PDM (Power Distribution Module), DDM (Drive Door Module), ADM (Assist Door Module), ECW (Electronic Control Wiper), CLU (Cluster), MFSW (Multi Function Switch), PSM (Power Seat Module), SCM (Steering Control Module), PTM (Power Trunk Lid Module), FBWS (Front Back Warning System))
Case1: After short between ADM CAN Low Line and High Line, short to ground together.
Case2: After short between ADM CAN Low Line and High Line, short to power together.
*This code is occurred when It is not possible to transmit data by CAN Line in those way of Software and Hardware. But, It is possible to receive data by CAN Line.
This code reports BUS OFF status when data transmit error count number is over 255. The purpose is to verify the status of CAN controller and CAN communication line when error is detected.
According to operation condition, some of module which are connected to CAN line may not detect B1603. Also, B1602 coincides with B1603 at all times.
| CAUTION | Difference between CAN ERROR and CAN BUS ERROR CAN Error: MIL On, CAN Bus Error: No MIL |
