Active Blind Spot Assist and Active Lane Keeping Assist Inoperable

[design4p]

Hi,

I have these error messages - Active Blind Spot Assist and Active Lane Keeping Assist Inoperable.

My local garage has checked for fault codes but nothing showed up.

Could this be a radar fault and their fault code finder unable to see the fault.

Any assistance would be most welcome.

Regards John

Moving this off the Icarsoft thread as requested by @KillerHERTZ (although it is Scantool / Icarsoft related for diagnosis) .

In response to your question. Yea the warnings came up before I replaced the battery. However they only happen after 20 to 30 minutes of driving. Seems to be something that warms up and then causes a problem. I was considering the possibility of a faulty relay.

Cranking battery replaced and the Aux battery shows a good charge and holding it even after the car standing for several days i.e. ~12.8v.

I sometimes get that when my battery's on its way out.
