Since last winter I have the ABS warning light and the ABS and Traction control warning on the display, permanent from the startup.
I have the codes read and it indicates C1145 wheel sensor front right handside failure and
C1095 hydrolic pump not OK.
I have the wheelsensor changed, cleared the codes but they immediatly returned, so basiccaly no change.
Next action is to measure the wiring harness and find a fault.
So in the whole trouble shooting process we ignored the C1095. So I wonder if we can and if we are on the correct problem solving track?

Thanks,
Luc

 

Hi Bleujag,

Is this the same car that you put in storage? Did you have storage/battery problems? Is the car coming out of hibernation? How old is the brake fluid? Important if you're dealing with braking systems.

Yep, you look to be on the right track. After the switch out of the ABS sensor, check the wire harness to the ABS sensor at the front right..
For the C1095 DTC, it's probably the ABS module, and there are numerous threads here on a common DIY solder fix on 2 pins on the PCB of the unit.

One recent example is below.

Pulling the unit seems to be the difficult bit and some threads seems to indicate that there are numerous USA repair "shops/resources" to fix the module . As you're in Belgium, you may have to find something similar nearer to you if you're uncomfortable hacking into a sealed control module.

 

Yes, the same car(2000 XK8 conv) , and the problem first popped up while doing the monthly engine start and roll. Since I had the battery on the itek charger I had no intermittant issues anymore. That 's why I knew that this time it was more serious..
The brakes are working fine, the car past the technical control. If the brakefluid level would be to low, would it gave also such errors?

 

Luc,

The ABS operates by a computer sensing different wheel speeds, via the sensors, and then activates solenoids in the ABS module to open valves that relieves brake oil pressure on the wheels. Hence all the pipes you see in/out of the ABS module. Bad brake oil shouldn't give an ABS DTC fault, but if the oil is really bad, it may jam the ABS solenoid valves, rendering the ABS less effective.

It was just a thought if your car has been in storage. A loose brake oil cap, while the car is in storage, would allow moisture to get in the brake system and seriously hinder brake efficiency. People talk about 4-5 year brake oil change period, but I tend to do mind every 2 years. You can never be too safe when it comes to brakes. Here in Bahrain, it's seriously humid too which doesn't help.

In your case, I would fix the bad ABS sensor first, and do a reset, then later check if the C1095 remains. Then it's time to tackle the ABS module either DIY or specialist repair.

Let us know how you get on.

 

Did you drive the car after replacing sensor? The code will not clear unless it is driven a few hundred meters.

 

Luc, don't forget- once you've cleared the ABS issue the light will stay on until you drive her for a short distance (just down the block for me, forget exact number).

Good luck with it.

Ok thanks guys for pointing out, that 's new to me. So I need to drive a short distance and then clear the codes, or will they be cleared on next startup?

 

They may even self clear, but if not , just clear after diving .

 

The codes will be logged in the module until they are cleared with a proper diagnostic tool.
The MIL might extinguish if the systems are functional but the fault will still be logged.

There might be a finite number of drive cycles that will clear the logged fault if there are no failures but I don't remember.

The sensors themselves are rarely the problem unless they are physically damaged. The link harness is almost always the problem.
