Has anyone made a can bus cable for any sort of project ?

 

Trying to setup a can bus link but i keep getting errors as follows on the tuning software :

 

 

I've made this cable twice now and can't figure out whats wrong.

What are you connecting (devices) to the bus?

these :

 

Possibly incompatible protocol?

Not so sure as I've followed the setup of how it communicates with the ecu.

 

Im sure it's just a cabling issue.

So the grey plug goes directly to the Link ECU via a CANPCB and CANF? If that's the case then section 4.1 of the Instruction

manual for the Can-Lamda device could be the issue:

 

"Each end of the bus must be terminated with a 120R resistor (1/4 Watt minimum). There is no CAN terminating resistor

in the Link CAN-Lambda Module."

Now fixed, Turns out the cable i purchased that said it was a genuine link can cable wasn't.

 

The cable colour order was incorrect so after i found a genuine looking cable i managed to reorder the colours.

 

Plugged it in and hey presto its working.

 

 

New bus cabled made after i botched up the last few; hopefully after identifying the fault this should work first time.
