Quick Hello
I'm Andy 23 a Mechanic in East Anglia, just brought a 406 on an X plate with the 1.9 TD engine, currently figuring out how to wire up the trip meter manually as i like gadgets

Welcome dude

Do a search, im pretty sure someone on here has wired up a trip computer before.

That would be mr MJB

Welcome.

I'm just trying to work out why you have a 2000 (X) 1.9TD as all the Diesels were HDi's by 1999

It is an HDi
I dunno what the hells in it i;m too lazy to lift the bonnet and check - yes i am a mechanic worrying isnt it!

Quick search for "trip computer" returns this thread:

viewtopic.php?t=154 (see page 3)

There's no step-by-step guide because I never got round to doing one, but I did put what wires go where. Note that you're on your own with the all-important ECU wire. Don't connect yours to pin 32 on the ECU unless you've got a Bosch 3.2 ECU, which you probably won't have otherwise you risk bricking the ECU...

Cool thats the thread i;ve been working from
Just ripped my display out as there was some mention of a switch on the side of the display, unfortunately cant find this so dissasembled the display and now none of the bulbs in the display work! Have i killed something?

Ah now that's because MJB's is a D8 and yours is a D9, completely different animal. I don't think anyone on here has done a retrofit of a trip computer to the D9. which makes you the guinea pig!

As for what you've done to the display, I don't know but I don't like the sound of it

Good luck

Oops! I missed that one

You could try the wiring diagrams in the D9 Haynes to work out what's got to be connected where, but if it works on the CAN bus it's probably not going to happen.

As for the bulbs, try shining a torch at the screen. If you can see what the display's trying to show, it's just the bulbs gone - you can try just replacing them - otherwise something major's happened to it. Could just be you've not put the connector back right tho.

I've gone and brought a car with canbus? Eurgh thats gonna be nothing but a headache! Spent far too long working on CANBUS at college last year it sucks!

Is this the thing that Haynes refers to as "systems interface"? That black hole on the wiring diagrams where you can't follow anything anymore...

BSI mate, Built-in Systems Interface, or as it's been previously referred to, a magic box full of fairy dust.

Hold on, we seem to have an expert. Hello Andrew!

Post by **steve_earwig** » Sat Oct 13, 2007 3:08 pm

I've been having a surf for it (in between washing my cars and gardening) and the idea seems an obvious progression, it's like a car ECU with 2 busses for equipment with varying priorities (think IRQ), the CAM (for important stuff like engine and ABS) and CAV (for less important stuff like ICE and air con). Apparently it's done to avoid having 13 kilometers of wiring inside every car.

All very nifty and "high tech" but I guess we're another step closer to buying cars with no bonnet release. Or at least just a big cover with just the dipstick and oil filler cap poking through... Hold on, I already have something like that. "No user servicable parts inside".

So, hands up who's never seen a Blue Screen of Death? Whats the automotive equivilent to Ctrl Alt Del? Headlamps horn fag lighter?

At least now I understand what this is about:

Honest John wrote:Water has been known to get into the ECU creating short circuits and causing things like the car to attempt to self-start while the alarm goes off, the wipers wipe and the screenwashers spray screenwash fluid. This seems to be increasingly common.

Another reason to fix the handbrake...

Had my aircon panel go on a hot day, D8 so not BSI, I did the old style Ctrl Alt Del -> BRST (Big Red Switch Time - remeber those on computers) Clutch down, switch off and on again, clutch up to restart. All fine after that

Has anyone else seen that Navy jobs ad where the guy reboots the computer by flcking the switch. At the end the shot pans out to show the vessel is a submarine!!
