08 s320 CDI many faults


Just trying to get more of an idea where to start really. I have done the basic visual inspection and some active tests including probing the n14/3 glow plug output stage for continuity. It tested o.k for the plug pin number 7. I plugged it back in and retested and fault still there so not just a loose connection.
I also removed wheel and looked at the abs sensor and wiring it looks o.k I think this car has been sitting outside in the weather to much which hasnt helped.
Attached pics of faults in star.
Once the batterys charged up again is there any recommendations for tests to run?
