The G4X 350ZLink ECU receives the following information over the vehicles CAN (Controller Area Network).

 

CAN Function

CAN DI Freq 1 - LH Front wheel speed

CAN DI Freq 2 - RH Front wheel speed

CAN DI Freq 3 - LH Rear wheel speed

CAN DI Freq 4 - RH Rear wheel speed

CAN DI 1 - AC Request

CAN AntiTheft - see Anti Theft

Gear position (Auto trans only)

Shifter Position (Auto trans only)

 

The Engine Fans and AC Clutch on a 350Z are controlled over CAN and the Link ECU sends this information out via the Engine Fan 1&2 runtimes and the AC Clutch runtime. To make the Engine Fans work correctly an output must be selected (for engine fan 1&2) so we recommend selecting an unused virtual auxiliary for each of these functions.

 

An additional CAN1/RS232 connector can be found on the ECU:

 

CAN bus 1 uses a 5 pin connector and is labeled on the ECU as 'CAN 1/RS232'.

If using this connector for CAN ensure the cable being used doesn't have Serial wires connected as this can act as an aerial and prevent USB communications from working.
