Hi guys this is a weird one! Unfortunately as well warranty is now out...

So driving on dual carriageway yesterday and then town road today I noticed on some rather forceful acceleration that the brake warning and engine management light flicked on for a sec then went off.

Can't really describe the car as having a problem when this happens either. I did scan the ecu for errors and got B1317 and the recurring U1900 might try scan it tomorrow with f super and see but I can't think what it could be.... Anyone got any thoughts what might trigger both at the same moment and off at the same moment...?

 

EDIT: come to think of it (will probably have to do a self diagnostic bulb test) but it could I suppose be the ABS light that popped up, so I suppose it could be an ABS sensor, will slam the anchors on, on a quiet road tomorrow and see what happens...

Ok so it happened again this morning and it's definitely the abs lights. I red lined 6 of 7 gears and couldn't force it so it's not engine related it happened at 40mph as well as 75 so doubting its speed. Noticed that the trip computer / gear and indicator windows where flickering when it happened.

F super isn, working for one reason it let's me connect but not choose an ecu so may need a fresh install

any thoughts...?

Ok so got f super up and running b code is apparently high battery voltage.... Checked fuse boxes both dry so no fluid damage will just have to see how driving home tonight is... ,

Drove home uneventfully so will take the Haynes manual to work tomorrow and think about what to do next whilst I design my lighting...

haha, this seems to be turning more into a diary!

 

well having slammed the ABS on a couple of times yesterday I have now had two 30 mile trips with no flickers. Perhaps the sensors needed jiggling loose, and perhaps the slamming on of the ABS was sufficient to resolve it. If I get the chance I will probably still try and clean the sensors up, but for now its a wait and see game!

:@ bad weekend followed by bad start to the week.

 

So, over the weekend,I took a drive to our local asda, after around 2 miles, the ABS light came on and stayed on. Checked the DTC Codes:

 

U0415 - Invalid Data Received From Anti-Lock Brake System Control Module (my suspicions where a duff sensor or one needed cleaning)

P0500 - Vehicle Speed Sensor Malfunction (ties in with the above,  http://www.obd-codes.com/p0500)

C1145 - Wheel speed sensor RF input circuit failure (ties in with the sensor issue)

B1317 - Battery Voltage High

U1900 - CAN communication Bus Failure

 

Had a wander round Asda, came back and on heading back home, the ABS light went away...

 

Thinking that it might just be a sensor, I got in the car this morning hoping that all would be well. Got in, drove away and just as I am up to speed on the motorway the error comes back:

car is in manual mode, 5th gear, and with no fluctuation of power to my right foot, the revs surge, then drop, the ABS and Brake lights flash, then the car goes back to normal. Then a minute later, it does the same thing again, then recovers again.

Third time unlucky - whole car just dies!! no electrics, the only exception is a nut job flashing immobiliser light like I just used the wrong key to try and start the car. Everything else is dead (expect the 12v outlet!) the screens go, indicators, everything. Pulled up on the side of the motorway, disconnected the battery, reconnected after a minute or so (rush hour on the side of the motorway trying to fix your bus - NOT much fun!)

 

Anyway, got her started. got to the nearest petrol station and after topping up, checked the error codes, on top of the above (hadn't cleared it since yesterday) I now have:

 

B1318 - Battery Voltage Low

B2286 - +5V Reference Fault? or  SIM Card Failure? or MODE switch sticking

 

So... This looks fun!

Hi Jeebo

Sorry I never noticed this thread until this morning.

This really doesn't sound like a easy one to diagnose so I guess it's best off with a specialist to be honest.

But I do hope it's just a bad connection or something minor

as do I Stef, I am however anticipating not. my gut is telling me a faulty instrument cluster causing some sort of chaos for the ECU, or a wiring fault elsewhere!

Just had the call from Ford, no errors could be reproduced. Due to the description of the error, they suspect it to be a wiring fault, they would replace the wiring harness at a cost likely to exceed £1000. and that wont even guarantee a fix...

Have you checked the abs sensor wiring/connection etc? And even tried a new sensor? Surely thats cheaper than a full wiring harness! Worth a try first

£1000 to replace a wiring harness?

Replacing a sensor is fine Dan but what one lol. And usually the need to be destroyed to remove them

I would have done so, but thats if it was only the odd ABS light, now that the car is going back to its earlier days, the car is cutting out on me, at speed on motorway just shutting down. Unfortunately to say it, I am going to have to chop this one in I think, perhaps get a new one. I cant trust it, and the guys who sold me it dont give a hoot, they didnt check the car properly, just told me what I wanted to hear... I cant trust it. Mrs doesnt, and given that its now cutting out on motorways and a £1000 bill is not even guaranteed to fix it...

 

I am struggling to think of how to keep it, I am looking at other CMAX's but I have a feeling if I keep this one, I will be tempted to drive it into the garage that sold me it...

ok this definately sounds like an ABS sensor issue mate. The speed is taken from the ABS sensors (found on IDS) anyways this got me thinking...You know i harp on about ford using PSA engines etc well this may be a little trinket of info...the majority of PSA have ABS issues due to the mount the abs sensor sits on gets a lot of crud on it and moves the sensor...  

 

The fix we came up for this was to remove the sensor, clean the mount, and reset the airgap back to 2mm (distance between sensor and ABS ring).

 

Your probably thinking yeah thats not it but when i had a 307 and got this issue i had alsorts of faults come up, such as;

 

- speedo danced

- handbrake on warning when stopped

- abs kicked in all time under normal braking (kinda hairy at traffic lights/junctions)

- STOP lights

- Engine management light

- catalytic converter fault and a whole list of random errors (french for you)

 

The only time this stopped was when the ABS warning came on and the system turned off (speedo still danced)

but the only fix was above....maybe worth looking at this weekend to save some £££'s

 

 

EDIT: further to my last, i just reread your last post... Have you checked the earth straps on this car?

Thanks for the reply John,

 

the earth straps appear fine :( thats why its such a nuisance, it seems like it is grounding correctly but still over juicing and temporarily blowing the electrics to the entire car...

 

Got the car back, Ford quoting 512 just to redo the wiring harness, its also got a cracked turbo pipe, so theres another couple of hundred...

 

off the back of this problem its caused a lot of stress at home amongst the family, I think even if I was to try and fix it, with the possibility of spending as much on repairs as I purchased it (ford said that it could be the ABS module and due to the shutdown, may even need a new ECU :() then I dont know if I can keep it...
