Better late than never.. sorry for this.
Here is the official wording from the DTC book for code C1266:

C1266 ABSCM Anti-lock braking Modulator solenoids power supply circuit fault Y JB45
-06
Modulator solenoids power supply circuit: open circuit, short circuit,
high resistance
ABS modulator failure

C1266 DSCCM Dynamic stability control Modulator solenoids power supply circuit fault Y JB185
-06
Modulator solenoids power supply circuit: open circuit, short circuit,
high resistance
DSC modulator failure

 

tell me about it... Unfortunately I don't have any other place to go, is the single dealership in town...

My module was an used one too except the car I got it from it was almost new. I just conected the module and put carefuly the hood over it and drove it slow. The light was off. Then I decided to go to the dealership to have it replaced.
You should be fine too.

Cheers!

 

Hi Tracus,
I paid for $112 for one abs module # 0 265 222 021 1x43 2m110 AF on ebay. I got the part and changed today. those two warning light, "asb" & "brake" don't light again after driving out. Finally. it is the problem like yours. Cheers.

Glad to hear that everything is fine!

Cheers!

 

HI tracus,
updated information: it has been running well for more than a year after installing the right abs module.

two days after installing the right abs control module, my 2003 x2.5 runs well and everything works as perfectly as it was the new one. I am so happy. thank you for your disclosed experience here. Maybe I could summerize and add some more meaningful points here for those coming x2.5 jaguar owners with abs problems. Here is the case for which you have to change a new/used workable abs module b/c the following:
1) abs & brake warning lights pop up when the car start running over 4miles/hour. brake warning light sometimes goes off and on.
2) all of the brake lights are ok. all of the brake components and tires are ok in right thread numbers, size, and air pressure.
3) all abs wheel speed sensors are clean and their resistance value are not too large (broken) or too small (shorted). R value should be between 1-2 k.
4) pin 15 is powered.
5) cruise control works well.
then don't worry about the risk of performance right away. search a valuable abs pump/control module on ebay with the right numbers such as 0 265 222 021 1x43 2m110 AE (AE or AF is interchangable, meaning ok).
6) installation: just change the module not the pump. It is an easy job of handling 6 screws only. It does not need to reflash (or socalled reprogram) at the dealership.

today 02-02-2011, it still works perfectly.
today 11-15-2012 it works well.

tracus, do you have anything to add?

 

Is nothing left for me to say. You did a very good job with your last update.

I am very glad you are happy though. I know how you felt...

Enjoy the ride man!

 

Hi Sienlee

I have ordered a replacement unit. What do you mean no need to reflash? Does this mean it does not need reprogramming to the vehicle

Thanks in advance
Dave

 

Just to add, my module is also 0 265 222 021 / 1X43 2M110 AE, light comes on shortly after driving off

Do not have the codes but it was tested yesterday and 3 sensors showing 0kmh at 37kmh, the other one showing correct speed, but the working one showing 2kmh when stationary, so I'm sure it's the module and not 3 sensors gone at the same time

Sienlee, did you just replace the electronic module that is screwed to the aluminium valve block?

Thanks again
Dave

 

Hi

Just bumping this up hoping one of you x-type experts can provide an answer

See below, can I split the electronic module from the valve block and replace just this part...is there any soldering required?

Then does it need programming to the car afterwards? Sienlee implied it doesn't

Thanks guys

 

Stupid question...Is their a ford equivalent of this ABS module?

 

I need this answer as well. Do I need to change the whole thing as one unit or can I replace the module only??? Anyone???

 

I will try only the module first.
I don't know if Ford has a similar product that will fir, but it is a valid question. I assume it might...

 

Hello forum members, I have this same annoying issue and so a question before buying a new ABS sensor. As long as the ABS module is with or witout DSP, what is the module compatability across other X-Type models (2.5, 3.0) and years?

Thank you all in advance.
Chris

TODAYS ISSUE
code C1145 .front wheel sensor?

ON GOING LONG TERM ISSUE
PO171 and P 0174 .........vacuum leak /lien ec ?????

Re long term issue / .have used various dealership etc..no luck.$$$$$$!...../.any dealer /mechanic you can direct me to?

thank you

 

What does "FOLLOWING VERY POSTS!
white rock bc /Jaguar x series 2002 2.5 auto" mean?

C1145 is an issue with the right front speed sensor.

What has been repaired or replaced for the P0171 and P0174 codes? Have the "usual" PCV hose been changed ti teh ribbed rubber one from the smooth one? Have the IMT O-Rings been replaced? Has the brake booster hose been replaced? Anything else? What are the symptoms you are having?

 

P0171 and P0174 codes
ribbed rubber one from the smooth one?.......... YES
IMT O-Rings been replaced?......... YES
Has the brake booster hose been replaced? ......NO {SIMPLE REPLACEMENT?}

Had the usual vac tests /smoke tests etc / Secondary engine light comes on and then goes off...quiet often when going up a hill?
MESSAGE CENTRE "cruise not available"....Car runs OK ......Now mechanic suggesting fuel injectors!!!!

ANY THOUGHTS APPRECIATED!

 

Change your brake booster line and MAF.

 

Changing the brake booster hose is a five minute job at the worst. Anyone can do that. And change that speed sensor and then see what you have.
