LN3 Computer/s **** itself

[Lex]

Just googled and it seems L36 is correct and that's the engine in it, I'm new to commies so my apologies for confusion

Is your motor supercharged?

Nah, supercharged is L67

Nah, supercharged is L67

Thought your title l63 was just typo?

Well yes and no.

Here in Australia we call it an ecotec V6, Holden/GM use LN3 as the RPO engine code on build plates and the Yanks refer to the engine as L36 (instead of ecotec).

Interestingly, It's actually part of the Buick V6 family, https://en.wikipedia.org/wiki/Buick_V6_engine


But back to your engine/computer problem. I don't think you have a engine computer problem. There is no safety that magically sets stuff off at 82°C coolant temp as that is well below the normal operating temp. But a lot/most of the fault codes you are getting centre around the BCM.

If you disconnect what ever you are using to monitor engine temps does it fault still occur?

After codes were cleared this was first thing I tried, still repeated. Could it have something to do with the slip ring fault causing a sort of reaction? As I said the anti-theft likes to throw a hissy fit at times even with the original keys

This might help. The original PDF is huge so I've broken the diagnostics section up into 3 parts

Will give these a flick through, cheers
