Weird startup faults

[Rochefort]

Evenin All,

 

Hopefully the right forum for this one :S

 

I've got a weird issue where every now and then when I fire up the ute, she decided to play up.

 

So its done it in two different ways

 

1 - Speedo stopped working, everything else seemed fine

2 - Traction control light comes on, gear indicator flashes. Think its in limp home, seems sluggish to take off.

 

Apply 101 IT fix, and turn it off and back on again and shes usually right as rain.

 

It is intermittent, seems to be if I turn the car from off straight to on it will do it more often, like there isnt enough power flowing at the start so it chucks errors.

 

So if I run forscan to pull the DTC errors out there are a bunch of errors, lots of them.

Rather then making this post 50 miles long (its a big log) I've attached the faults.txt dump out of forscan.

 

If I clear the codes, the only error I get is, and that's after startup and running the Key on PCM tests.

 

===PCM DTC P1000-60===
Code: P1000 - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete

 

So no surprises there.

 

I ran the ABS and TCM module tests and they all came back clean.

 

It is also work noting that a mate brought his HP tuner stuff in and ran through it on Monday and it was fine (I had cleared the codes after last time it happened)

 

Not sure what else to look at, so checked the B+ Voltage which came back 12v off and 13v on, the ignition voltage (not quite sure where it grabs it from) was 13.6v so looks like the alternator is doing its thing and the battery is nice and charged.

 

I did read somewhere, on a different ford, that the ECU wire can cause faults similar to what I was having.. I assume by ECU its the PCM module in the engine bay... What I can work out, is how to get the bastard out to clean the plugs and what not, it looks to be riveted or something in?

 

Just in case I didnt do my profile properly, its a 2008 BFII XR6T :D

 

Thanks in advance

I get the same thing in my bf 1 turbo. 

I find 9 times out of 10 if I leave it on the reds for a bit and don't rush it it doesn't do it. 

I thought it might be battery related. 

My old bf sr done the same thing. Turns out the alternator was stuffed and the battery while reading good was cactus also. New alternator in and new battery fixed it.

Does it only happen when you give it some acceleration?

 

Mine would drive fine but soon as I laid the boot in the revs would spike right up, speedo drop out, ABS + T/C light would flash. Restart car and speedo working again.

 

Was caused by a Cracked ignition coil that was still firing fine (so wasn't throwing a specific code) was the cause. You've got some of the same codes that mine was throwing when I had this issue. ( U1900, U2514)

 

My other suggestion is to make sure your battery terminals are clean.

Funny, I think the same.. If I let the car power up all the accessories then crank her it seems fine.

 

The battery is about 2yr old, wonder if there are other tests I can do on the alternator.

Only does it on start up. If it doesnt fault on start, it all good.

I've driven mine with the speedo not working. It only reads litres/hour and no cruise. Gave it a bit on an on ramp and it felt like it hit a brick wall. Got it home turn it off and back on again and it was all good.

Its the whole lot too, when my speedo did that I flicked torque on my head unit and it wasnt getting data for the speedo at all, had to use Waze for GPS speed.

hmm, weird.

 

All I can say is still check the coils but I'd be looking at earthing faults as well. Even back to the actual battery terminals which may look clean but actually have a layer of crap on them where they contact the battery + and - posts.

 

This is the coil that caused all my problems. There was NO fault codes todo with the coils. Highly recommend a visual inspection as well as inspecting the wiring going to the coils (can be accidently crushed where the cover fits back on).

 

 

hopefully you can resolve your issues soon, whether its coils or simply a bad earth or something. hopefully nothing major

Torque on your head unit? I've only got the stock icc in mine. Quite boring actually. 

I've checked my terminals John but I think I might have another go at them with some white vinegar and clean em up good. I'll check the coils on the weekend also.

Yeah I imported a Kenwood KVT-7012BT 7" LCD jobby from the states, gives me full mirrorlink control with my android phone. Can run torque, forscan etc.. all from the screen.

Back on topic.. :D

 

Seems to be a few threads here with coil pack issues around the 200k mark, im around 176k so heading in to that territory. Of course being an old school car owner previously, I had to google what a coil pack was... Explains why im missing a dizzy and some spark plug leads :D

 

I do love owning a ford again over an imported toyota though... Alternators cheap... coil pack sets, unless you go the Weapon X ones (which looks like arent worth it) arent terrible either.

Check your battery voltage while cranking, I'd be willing to bet its dropping below 10v.

 

Thanks for the pics of the KVT-7012bt I'd been thinking about a flip screen as per what you've done.
