PT (Powertrain) CAN: Introduction: Notes

The PT CAN is the fastest CAN bus in the E65. It is an existing bus system. PT CAN stands for powertrain CAN. It links all control units/modules associated with the powertrain. All the bus nodes are connected in parallel with one another. In contrast with the previous bus, (two-core twisted pair) it now has three wires. The third wire of the bus cable is used as the wake-up line and has nothing to do with the actual CAN bus function.
