Problem:
I have this error on VXDIAG VCX SE Renault Clip with an old renault car is it normal? saying probe is not compatible with the car.
Solution:
It is normal. VXDIAG and some other J2543 passthru devices are not good on older K-line Renault cars.
VXDIAG supports Renault (CAN BUS models) from year 2005 to current.
If need to diagnose older Kline Renault, get a CAN CLIP interface or universal scanner instead.
