    P38A tapping into BECM signals with an arduino

    The Arduino board I got for £3? Hmm... Seriously though I did buy an ECU and switch from a disco but a) the switch isn't debounced, so it's a pain to consistently press it for just the right amount of time. b) it doesn't trigger with ignition on / off (as far as I know) and c) the connectors are...

    P38A tapping into BECM signals with an arduino

    It's pretty straightforward, the disco 2 bracket tapers from the outside to the inside (nearest the car is thickest). You just need to cut the whole thing down so it's one thickness, start with your blade flush to the bottom of the bracket at the outside edge and cut downwards so you're cutting...

    P38A tapping into BECM signals with an arduino

    So.... I went with just checking if the ignition is on to trigger fold / unfold (there's also a button you can press) https://photos.app.goo.gl/qshLHKa2wYzqBdB1A They're Discovery 2 mirrors. If you saw off the bottom half of the ally bracket it slides nicely into the plastic bit from the P38...

    P38A tapping into BECM signals with an arduino

    Cheers @martyuk! I do have a bit of electronics experience, built a few microcontroller things in my time so not really worried about the mysteries of the becm (famous last words before frying it) Like you say, I'm much more likely to fry my arduino type things, but they're cheap as chips...

    P38A tapping into BECM signals with an arduino

    Ha, I have a spare unlocked Becm sat on my desk so I should be okay if I manage to kill my current one. Pun intended :D

    P38A tapping into BECM signals with an arduino

    God no, I'm not going to do any reading of fault codes or anything, I just want to live monitor some of the signals coming out of the becm. The ones I'm interested in all appear to be 'pull to ground' type things, which are reasonably easy to monitor. Once I have the powerfold mirrors sorted...

    P38A tapping into BECM signals with an arduino

    To start with I want to trigger something (a powerfold mirror) when the door is locked / unlocked but only when the motor isn't running. Longer term I might build a web based dashboard showing engine status, road speed (this is available on one of the pins from the becm), alarm status etc...

    P38A tapping into BECM signals with an arduino

    Hi All, I have a couple of projects I want to integrate into my 2001 P38, but doing so requires picking up some signals from the BECM. First off, I want to get access to the 'engine running' (C1279 pin 9) and lock / unlock (C1283 pin 8, 18) signals. I'll be using standard 3.3v GPIO on...

    P38A Replacement of OBD2 port?

    My OBD2 port in my 2001 P38 is knackered (due to water ingress). Has anyone replaced this on theirs? I know I can look at Rave, figure out how to get the connector out etc, just wondering if this is common enough for their to be a 'how to' anywhere?

    P38A Water in passenger footwell

    Hi all, So, bit of a strange one, although it might be something really well known / obvious. On my UK (RHD) 2001 P38, I get water in the passenger footwell when it's rained and I put the air con on or heater on (so when the fans come on basically). If it's rained and I don't have the fans...

    P38A Headlining replacement, Manchester (UK)

    Hmm, might give it a go myself..... the suede black one looks nice, not sure it will go with my current lightstone interior though

    P38A Driver's door knackered

    Ah ha, that's the bugger. Saved myself £3 by using a bit of wire and a drill :)

    P38A Headlining replacement, Manchester (UK)

    On google? Yup, loads... I was just after recommendations from anyone on here who's had it done :) I guess a trip to Taunton might be on the cards.

    Disco 2 Hacking powerfold mirrors

    Okay, my ECU arrived today, just need to figure out the connections now. I don't want to buy a whole wiring loom for the disco when all I really need is the ECU connector!

    P38A Headlining replacement, Manchester (UK)

    I'd rather pay someone £200 that spend 4 hours arsing about with it :) I'm happy doing oily stuff or electriconic stuff, but fiddly bits of interior are not my bag :D

    P38A Headlining replacement, Manchester (UK)

    Hi All, apologies if this isn't the right forum for this... As the title says really, I'm in Manchester (UK) and looking to get the headlining replaced on my 2001 P38. Maybe get the seats re-done at some point as well. I've found a couple of places that look promising, but they're down south...

    P38A Driver's door knackered

    Okay, so on dismantling the door handle I found that the end of the handle that goes into / out of the door when you open it slots into a plastic part. That plastic part converts the forward / back motion of the handle into an up / down motion and is connected to a rod, which then opens the...

    P38A Driver's door knackered

    Update: after a lot of messing about (and swearing) I gave up trying to hit the latch inside the door last night at about 10pm. After locking the car up, I walloped the outside door handle so it pushed back against the door again. There was a definite 'clunk' from inside the door but at that...

    Disco 2 Hacking powerfold mirrors

    Hrm.... nope, I hadn't given any thought to that. Interesting. It sounds like the D2 is significantly simpler then, I just need to hack the current P38 switch and wire it directly to the mirrors OR replace that switch completely with either the D2 switch / something else. Either way it's...

    Disco 2 Hacking powerfold mirrors

    Ah cool, so as long as pin 6 is only 'ignition live' the mirrors will fold in / out with the ignition state? I thought the Disco2 ones didn't do that, and only folded with the button? Thanks for the help with this, it's much appreciated!
