General Description
This is DTC which is related with communication error between CLU and other units.
- Body CAN communication Control Units: BCM (Body Control Module), CLU (Cluster), 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.)

DTC Description
| Type | Condition | Remark |
|---|---|---|
| 1 | CANH Circuit Open | B1602 is presented when IC detects one of errors among 7 types under normal communication condition. According to operation condition, some of module which are connected to CAN line may not detect B1602. Also, B1603 can be detected together. |
| 2 | CANL Circuit Open | |
| 3 | CANH Circuit Short to Power | |
| 4 | CANL Circuit Short to Power | |
| 5 | CANH Circuit Short to Ground | |
| 6 | CANL Circuit Short to Ground | |
| 7 | CANH and CANL Short to each other |

Scheme 170
This is DTC which is related with communication error between CLU and other units.
Control Units: BCM (Body Control Module), CLU (Cluster), SMK (Smart Key), SJB (Smart Junction Box)
Case1: After short between CAN Low Line and High Line, short to ground together.
Case2: After short between 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 |
| CAUTION | CAN Error: MIL On, CAN Bus Error: No MIL |
