DTC B1603-00: CAN BUS Off: General Description

WARNING: This page is about a different car, the 2021 Kia Soul. However, it is still accessible from the selected car via links, so may be relevant.

The Wireless Power Charger (WPC) uses a magnetic induction method. Induction chargers typically use an induction coil to create an alternating electromagnetic field from within a charging base station, and a second induction coil in the portable device takes power from the electromagnetic field and converts it back into electric current to charge the battery.

The main features of Controller Area Network (CAN) bus system are:

A data-transfer rate up to 1 Mbit/s for the high-speed CAN and up to 125 kbit/s for the low-speed CAN.
Signals are broadcasted in both directions.
The multi-master principle.
High availability by locating failed control units.
Standardization in accordance with ISO 11898.

The WPC communicates via B-CAN communication line with Integrated Body Control Unit (IBU), Integrated Central Control Unit (ICU), Cluster (CLU), and Smart Key (SMK) module.
