There are cars with a check control module and cars without it.
Then there are OBCs with check control enabled, and OBCs with check control disabled.

If you have a car with a check control module, you need to enable check control on the OBC, otherwise it won’t work and pressing CHECK will only light up all segments.

If you have a car without a check control module, you need to disable check control on the OBC, otherwise it will always display CHECK CONTROL INACTIVE error.

If you have a car with a check control module and check control enabled on the OBC, it will display CHECK CONTROL OK, or an appropriate error code if there is something wrong with your car.

If you have a car without a check control module and check control disabled on the OBC, pressing the CHECK button only lights up all segments on the display.

Have you read the BMW On Board Computer (OBC) secrets! post. I think you'll find a way to read the engine temperature. I don't know about Oil pressure. Just search there for "Engine temp"

Hi,
Does anyone know if E36 18 button OBC can display oil press and water temperature and how to make this display?

hy; back again.

The master reset in the secrets menu will not solve the problem.

For my the thing is solved and I am doing other stuff on my E36 (the multifuncion steering wheel is finish as the electric seats with heating, the business radio too, now i am doing the Mp3 Cd bmw changer and if I am lucky finding the parts the bluetooth sistem for the phone), because I reprogramed my OBC to a newer software and all is working as it should.

@ vlakci
It looks like, on the contrary to all of us, you are not going to give up on this issue before it is solved. My hat off to you mate, I’ve long given up on trying to understand the OCB functions on the E36, but maybe I’ve given up because my 18 button works fine.
however, I tried for 6 months or so to work out all the functions and their actions, but gave up after frustration took the better of me. Not even BMW Tech seem to know what does what on the OCB settings.
So my friend, if one day you crack the MYSTERIES of the BMW E36 OBC, I think they should but you in Who’s Who!
Keep it up, and brake a leg, as they say! (not really brake your leg mate I really wish you all the luck in the world, you going to need it…) LOL

I wonder if a “Reset” of the OBC would cause the OBC to find the codes it needs on its own?

I have a ‘92 E36 325i with Check Control, and did the 18 button swap, and too am having the Check Control now inactive. At least there is a place here where we can hash out ideas to solve this. Thank you all for your ideas and suggestions. If I had any, I would gladly post them here.
