ECU count

INEOS 7 ECU's and yet so many gremlins unresolved. Waiting.

INEOS 7 ECU's and yet so many gremlins unresolved. Waiting.

Sadly not sure why the article says 7 because it is not 7 it is 35 in total according to Ineos. Even if they are talking just major compute I count 9-10.

ECM, ECU, FCM, BCM, SCM, TRM, HU, ESC, ACM, The OB2 Port for get what that one is called.

Rivian Gen 2's have just 7 true ECU's.

There should be a strong and stable bowden cable to do this which one can operate from inside the car. My 1989 G-Wagon had this to lock the diffs. A bit hard to pull, but no electronic problems - a simple yet effective mechanical solution.

It should not be too tricky to rig one up, esp if a hoist is available.. I'm a bit busy to do it myself right now , but those much more likely to encounter deep water should have a think about it.

And sadly they appear to be running on Windows 98..

This might work with some automatic implementations in some cars. But sadly not with the Grenadier. Everybody here will know, that the gearbox immediately goes to 'P' when you switch off your engine. And you can not put it back to neutral as long as the engine is off.


As far as I am concerned, this is not true. I am not negative about the Grenadier. But I can see some flaws which I don't like. And at least this comment confirms I'm not wrong:

I was talking about the transfer case. This solution works regardless of the state of the ZF.

As said, I use this "feature" frequently, e.g. to position the car before lifting. Others do so as well, lots of posts about that around here. So, there's nothing to prove anymore.

Solutions matter. Nothing else.

Absolutely! Used this "undocumented feature" several times. And there are more than enough posts in this forum that discuss this topic and confirm the same.

I'm convinced that the guys who are so negative know this....

Can you describe the procedure to do this? Is it in the unofficial manual?

Simply search for "transfer case neutral" using the forum search function. It directs you to e.g. here .

It's in the owner's manual.

It's no use having "just a few" control units in the car. The concepts are still catastrophically flawed.

For example: If you can't put the transmission in neutral (because the engine is not running or some ECU decides not to let you put it in neutral for some reason), you simply can't move the car by pushing it manually.

Perhaps the emergency measure of unlocking the transmission from underneath will help. I've never tried it myself. But if you're stuck in a muddy ditch or a small stream with 40 cm of water, you're in for a real treat. You can't even pull the car out of the mud with the winch.

That's exactly the case with the Grenadier – not just in the event of a breakdown, but whenever the engine won't start for some really stupid reason. Try moving your car half a meter forward to, say, get to your bicycle in the garage, which is blocked because the Grenadier is too close.Impossible! Without starting the engine, this isn't possible – which is, for only a few seconds, extremely bad for a cold engine.

It's a flawed concept. I've owned several automatic cars, but none of them had this iditotic restriction. Even if all control unit are functioning correctly, they are useless if one of them has decided that you're not allowed to start thje engine.
clearer description of what I mean with 'can't move the car'.
Think of:

• a dead battery
• an empty AdBlue tank
• an empty fuel tank
• a blown fuse
• any other another (non-)problem preventing the engine from starting.

There could be dozens of (harmless) reasons why you can't start your engine. Any one of them will ultimately prevent your Grenadier from starting.

Turn key to accessory mode, put seatbelt in (behind you, not on you), and you can put the car in N without starting just fine.
