    I have the same problem, but it could be the wire contakcts from the "brain" to the instrumentpanel on the passenger side. Bad contakt couse water etc. Check it - I did after engin change 2,9 to 4,0 liter. Moust of the problems was gone. Not the fouling failur couse i did not find the rigth plase for it.



    Good loock

    I had the same problem. Check the wirecontackts from the "brain" to instrument. Bad contackts etc water...so one.



    That was my problem + bad relay on passenger side

    I have same problem 97 Jag 55000 miles,,, Bulb failure but then bulb works ABS warning, low brake fluid warn but fluid full I had a limp home mode kick in one time, red light comes on then sometimes no warn lights at all for a while then sporadic bulb brakes abs etc.. I heard in a few places its a crack in the solder inside the ABS module... I went to take mine off and off course someone had tried to take it off before and nicely rounded off the tiny star nut so I am screwed unless I take an angle grinder to it.. Never the less I have seen pics of what the problem looks like inside and its a cracked solder joint fix is to solder the crack back up.

    Inside the ABS module is a weak solder joint open up and solder

Bulb failure light is from one of the relays found attached to each light... if one of them sticks the dash light will go on even if all the lights work.... solution.. buy inexpensive relays on line and substitute until you find the faulty one.....

Abs light on a 06 expedition


Having the vehicle checked for DTC'S - diagnostic trouble code's would be a good first step . ABS light on codes are stored . Suggest you take your vehicle to a qualified repair shop that has the knowledge an testing equipment to diagnose the problem properly .
Anti-Lock Brake System (ABS)
The 4-wheel, 4-channel anti-lock brake system (ABS) consists of the following components:
  • ABS module
  • Front wheel speed sensor
  • Front wheel speed sensor ring (integral to the front wheel bearing)
  • Hydraulic control unit (HCU)
  • Rear wheel speed sensor
  • Rear wheel speed sensor ring (integral to the rear halfshaft)
  • Yellow ABS warning indicator
  • As you can see here , it can set numerous

Hi ive got a jaguar s type 2.7d and having problem with parking sensors, would you know anything about them?


Hello
Check the sensors , you still might have bad one in the group which will effect the full function of the sensors.

If sensors are good , then you need to check the position of the sensors and set up correctly as if one of the sensors is out of alignment , it will cause this problem.

If not , the you need to check the electrical wiring for the sensors

The fault is generally due to a problem in the Computer & Output Circuit area


Fault Description: ECM HO2 Sensor control malfunction -bank 2 upstream (2/1)

Action of ECM:- ECM Default:- HO2S 2/1 control circuit inhibited


After clearing the DTC, complete the Drive vehicle for 10 minutes
Check for a reoccurrence of fault DTC.


Possible Fault:- HO2 Sensor 2/1 heater failure HO2 Sensor 2/1 sensing circuit: short circuit to ground, short circuit to high voltage, open circuit ECM Failure

Hi ive got a jaguar xtyre 2.5 v6 my car came up with a light on so i had it dieagnosed and it said it was bank 2 oxegen sensor so i changed it and the same fault keeps comming back up all the time help...


This happened to me and the problem was the other O2 sensor, Jaguar pointed me in the wrong direction, simple to check if you still have the old sensor fit it to Bank 1.

The brake light is on and the breaks are locked and wont loosen


this problem is almost certainly caused by a failed Anti lock hydraulic control unit, have the system tested to confirm this, the light being on indicates a failure of the system, a fault code will be in the memory of the ABS module for that fault.

95 jaguar xj6 no brake or reverse lights


Hi the Jaguar XJ6 works off a 12volt, negative earth.... Jauguar are a legend for electrical faults.... ok you need to do a voltage check/fault check on the system, remove the fuses from the associated problems, i.e the rear lights! place a volt metre over the contacts and there should be no voltage present! grab the wiring harness and move it side to side! if you see a rise in the volt metre then there is a short to the earth! this can be done through out the systen including switches.... i would personally check the earth contacts near he problem areas these corrode and you then get a short in the cicuit

Hope this helps.

Have error codes C1175 & P1000 for a 2002 Jaguar X-type 2.5.


C1175 ABS/TCCM Anti-lock braking / traction control LH rear wheel speed sensor circuit fault ABS/TCCM to wheel speed sensor signal circuit (FH33-21): open circuit, short circuit to ground, short circuit to B+ voltage, high resistance LH rear wheel speed sensor failure
P1000 is for check not complete after last memory clear , dont worry about it , just stick with C1175 , and most probably it is the sensor wire

DSC fault on display,car stops complete electrical failure.


Hi Jagman

I suspect this could be your battery at fault.

Get it heavy discharge tested first.

Good Luck.
