"Connected" ECUs

Several ECUs are connected to each of the two networks. The Gauge Control Module is part of both networks since it is the "Gateway" between them. Below is a list of ECUs and the network they are connected to.;

B-CAN ECUs 

• Gauge Control Module
• Relay Control Module
• Multiplex Integrated Control Unit (MICU)
• Door Multiplex Control Unit
• Combination Switch Control Unit
• Climate Control Unit
• Power Seat Control Unit
• HandsFreeLink Control Unit

F-CAN ECUs 

• Gauge Control Module
• ECM/PCM
• Navigation Control Unit
• VSA (Vehicle Stability Assist)
