EML light and ACC deactivated

[Lmass]

Hi wonder if anyone else had this issue. Intermittently I get a message in the dash saying ACC deactivated and my eml light will flash orange. I have plugged a reader in whole the light is flashing (not a very high spec one) but get no fault codes. There’s no changes in power with the engine and if I turn the van off and back in it’s cleared.

It’s a 2021 T6.1 T30 LWB
Anyone else had this issue

You are going to need to get a better scanner or get it scanned by someone who has one. the EML is lkely to be the route cause, and as a reaction the brain simply disables some non critical services like ACC, stop-start etc.

The cause could literally be anything that is thowing up a non-persistant EML, this will be logged however even if the fault is not present when scanned, so should be easy to find the cause with the right equipment.
