ATCM-Terrain Response Fault code

Looked at a couple of 2013 model year 4.4 SDV8's and they both have had this fault code picked up with the IID Tool which would not clear. I am familiar with L322's but not L405's, so wondered what it related to?

Sounds related to battery state.

Could be to do with the car sitting for a while.

If the terrain response seems to work and the dash isn’t showing a fault then a new battery or a good charge may sort it. There is nothing that can't be fixed with a hammer😜😜

Unnecessary quote removed

i have this code with my new to me 2013. i am also having codes related to the gateway module. when the car is fully charged on the battery charger, all the codes except the atcm code clear. they come back after a few hours off the charger. i am installing a new battery on friday when it comes in. i figure a new battery will provide a good baseline to work from.

Hi Bora20. Did the new battery sort your problems out?. 2014 L405 3.0 V6 Autobiography Santorini Black 49k

A new battery did not. The code hasn’t made any difference though.
