How to solve Nissan Consult 3 Plus NOT Connect to PC

 

This is for those with a Nissan consult 3 plus interface not connected to the PC.

Usually when users power it up, only the red power led comes on and nothing more.

Suggestion from experienced users:

1: close anti-virus program & disconnect internet connecton

Anti virus program oder firewall/auto protect activ

This software may disturb/block the vi- recognitoin routine of c3+.

in my case (using a passthru device) i disconnected the internet connection, deactivated the auto protect function and after starting c3+ again, the led became green….

I think to remember , you have to connect the original vi to the car and the laptop, both. Only connection to the laptop is not enough for c3+ to recognize the original vi.

2: check usb circuit on pcb and usb sockets on pc

If you have basic knowledge of checking the pcb and components internally, check the usb circuit etc. and have a try on another laptop to eliminate faulty usb sockets on pc

3: check wires, solder breaks, etc.

Use a multimeter and check for broken wires between obd plug and pcb , check for solder breaks on pcb where plugs and connections are soldered to, basic fault finding, check for pcb damage like scorch marks or discoloration and components for signs of stress or damage, use a high power magnifier.

4: check continuity

Then its a case of deeper fault finding using things like scope, function generator etc, check continuity with cable plugged into the interface in case one of the contacts is bad then follow connections as far as you can on pcb to check for breaks on the board.
