Circuit Description
WARNING: This page is about a different car, the 2002 Oldsmobile Intrigue. However, it is still accessible from the selected car via links, so may be relevant.
The Controller Area Network (CAN) serial data circuit is a high speed serial data bus used to communicate information between the steering angle sensor and the EBCM. When the ignition switch is turned to the ON position, the module and the steering angle sensor begin to transmit data between each other.
The CAN bus circuit is monitored continuously after the ignition switch is turned to the ON position.
