The Kia Code B1602 is an error code that is associated with a CAN BUS Physical Error. This type of error code is set by the ECM when there is a short circuit in the CAN High and CAN Low lines, including a short circuit between the two. The causes of this error code can range from a short to the chasis ground or battery in either the CAN High line or CAN Low line, to CAN Low being shorted to CAN High. All of these causes can be very problematic if not addressed properly and can lead to more serious issues with the vehicle. In order to avoid this, it is important to understand the causes of the Kia Code B1602 and how to solve it.
Causes and Solutions of Kia Code B1602
| Cause | Solution |
|---|---|
| Short to chasis ground or battery in CAN High line | Check the wiring and connections related to the CAN High line, and replace as necessary. |
| Short to chasis ground or battery in CAN Low line | Check the wiring and connections related to the CAN Low line, and replace as necessary. |
| CAN Low short to high | Check the wiring and connections related to the CAN Low and High lines, and replace as necessary. |
| Faulty ECM | Replace the ECM with a new one. |
When dealing with the Kia Code B1602, it is important to understand the causes and solutions behind this error code.
