Electronic Control Modules (Service Information): Communication: Description

All models use the Controller Area Network (CAN) protocol for their intra-vehicle communications networks (data buses).

Compared to its predecessor, J1850, CAN architecture offers the following improvements:

1. Eight times faster to ensure that messages reach their destinations in a timely manner (J1850 operates at 10.4 Kbs compared to 83.3 Kbs for the CAN system).
2. Built-in error checking capabilities for increased reliability.
