R-net ISM6 new fault

[greybeard]

I'm getting this fault code. Everything works with no problems so it has me puzzled. Anyone know what the code means?
If everything is working, how do I establish where the fault, if there really is one, may be? Thanks.

One of the bus cables connected to the ism will have an issue

Without wishing to state the obvious, bad cable?

It means its seen a data error, or a high resistance or something. Again, servisol/deoxit all of the connectors esp bus cables, of which there are 2 - 4 ends - usually. But also check all the motor, brake, battery, and actuator and inhibit connections too.

If it still does it, replace bus cable, if it still does it replace the other bus cable...

Rover was faster

Yes, John. I worked that out myself
I was asking about the code 7F00.

But thank you and Rover for the advice
