The CEL is normally not lit if just P1000 is present. Why were you expecting the monitors not to be set? The ABS/DSC issue is not connected to engine monitoring.

 

Maybe we should call it the Malfunction Indicator Lamp (MIL?)
I postulate that Jon got P1000 as a "thank you" for his several attempts at clearing the C1175. He hasn't yet completed the required drive-cycle for all the OBDII tests to complete and set the P1111. The CEL(MIL) remains on because the C1175 is still present.

 

Update:

After a week's postponement due to the sleet/snowstorm that played havoc with the roads in our neck of the woods, my S-Type finally goes into my trusted indie shop late tomorrow afternoon. Hope to have further diagnostics (and hopefully the associated fix) on my ABS/DSC issue sometime Wednesday. I'll try to keep this thread updated for those of you suffering from the same problem....

 

Update:

My trusted indie shop called me earlier this afternoon with their findings. They used their AutoLogic diagnostic system to successfully clear the C1175 code (which the two generic scanners I had access to would not allow me to do), swapped the two rear wheel speed sensors with each other, then drove the car. The C-code fault immediately followed the swap, meaning that the left rear wheel speed sensor itself is very likely the culprit. Rather than cough up $212 for an official Jaguar new rear wheel speed sensor, I chose to order a new generic sensor from SNG Barratt Group for about $56 using my forum discount. It must be shipped from the UK so it will take a week or so to get to me. When it gets here, I'll install it and then hope that several drive cycles in the car will clear all codes, warning lights, and messages. If that doesn't happen, I'll take the car back to my trusted indie shop and they will clear all codes and warning lights for me using their AutoLogic system while I wait....

Many thanks to Toby at Flying Circus English Cars for confirming the wheel speed sensor as faulty. I'm certainly relieved that we're not having to chase difficult-to-find broken wires somewhere between the wheel speed sensors and the ABS/DSC module....

I'll update this thread again once I have received and installed the new sensor. It will be interesting to see if drive cycles alone will clear the C-code fault and turn off all of the dashboard warning lights and messages. I sure hope so....

 

Good news Jon, That could have been a pocket buster.
Nice to have Toby in your stable.

Great news Jon, a repair that still does not break the bank. Well done to Flying Circus.

 

I hope that is a resolution for you Jon. I've been trying to find out if it is possible to test the sensor with a multimeter, i.e. passive resistance Ω and what a known good sensor should read?


Jon

 

They should all be about the same so just measure till you see what they are. (This works for other cars, too.)

However, this will not find all faults as they are not a simple resistor at all. (Read on the net how they work etc.)

 

+1 on that very good advice. Perhaps the dedicated multi channel scope with digital hold is still expensive, but these days it is possible to buy the same functionality in a multi channel "brick" and s/ware that feeds your average laptop - or better still, any Win tablet.

Is it time for everyone to review their toolkit if you maintain one or more of these cars?

1. Buy the car;
2. Get an OBDII tool - my choice Mongoose clone + IDS (AU$50);
3. Get a "smart charger" or "battery tender" (mine cost AU$100);
4. Use permanent connections and plug in whenever car is not in use;
5. Consider getting a 'scope "brick" + s/w for all signal/data work (AU$150).

Too expensive? I spent (relatively) more than this TOTAL for my 200ft-pnd tension wrench over 40 years ago when I bought my first Jag, knowing that it needed R&R cylinder head.

Step 1 is easy - pay the money and live the dream! IMHO, investing in 2-5 and learning the skills to use these tools diagnostically, has 2 huge benefits - (1) a far more reliable vehicle and (2) less maintenance expense.

Cheers,

Ken

 

Update:

Still waiting to receive my new rear wheel speed sensor from SNG Barratt Group in New Hampshire. My order was placed nearly two weeks ago and I still don't have an expected delivery date. SNG Barratt has really been slow on delivery for the past couple of orders I've placed with them. Very disappointing....

 

Not sure what's going on with SNG Barratt Group's U.S. facility in New Hampshire. They received my rear wheel speed sensor from the UK last Friday. As of this morning (Wednesday), they still have not shipped it out to me. I've called them every day this week and was assured each time that my order would ship out that day. It's not happening, folks. So be aware if you decide to place any orders with them right now....

 

May be SNG should be directed to these latest posts, Jon. Its amazing how fast companies move now a days when when reviews or negative comments are made about them on social media. Bummer its happening to you. At the very least the vehicle is still driveable.

Maybe today is the day the'll ship it out!

 

Rick,

Norri will contact SNG Barratt on my behalf. As a forum sponsor they need to let us know if their policy now is to sit on parts for a week before they ship them out to us (and still charge me $9 for shipping costs). We'll see what they have to say....

 

I agree very poor service. I gave them one chance for a quote on a rad and delivery.
Failed miserably on both counts.

Just because they sponsor something does not make them good.

 

SNG Barratt claims my Visa card would not process for them after multiple attempts. I've purchased from them before with this same Visa card. I've had it since 2002 and no one else has ever had a problem with it. If you cannot get a credit card transaction to process successfully, shouldn't you immediately call the customer to inform them? Hmmm....

SNG Barratt says all is well now and is supposedly shipping my rear wheel speed sensor to me today and not charging me any shipping costs. So we'll see....

 

Update:

My new rear wheel speed sensor from SNG Barratt showed up in today's mail so I jacked up my S-Type's rear axle, pulled the rear wheel, and replaced the suspect sensor with the new one. I had already cleared the ABS C-code and dashboard warning lights and messages with my new iCarsoft i930 scanner and turned off the MIL with my generic OBDII scanner so I figured everything would be back to normal as soon as the new rear wheel speed sensor was in place....

I then took the car out for a 10-mile test-drive and I'm pleased to report that all systems performed perfectly and no codes or warning lights returned. So my ABS/DSC fault was indeed due to a faulty rear wheel speed sensor. My new i930 scanner has certainly passed its first test with me....

 

Great news, Jon!

 

JonnieMorgan,

Any update on your C1175 DTC status? Mine did indeed turn out to be a failed rear wheel speed sensor. A new one fixed it....

 

Hello Jon


No luck here yet, glad you got yours sorted out. I've swapped the 2 rear sensors and no change, also a new Varta Blue type 019 battery hasn't fixed it either unfortunately.


The anomaly with mine seems to be the way the brake system "pulses" the brake on that wheel for the first few miles of driving, which I would have thought would indicate it is sensing that the wheel is travelling too fast?


I've spent hours going through the JTIS information and my next check is to test the voltages/resistance at the ABS/DSC control module. However the multimeter readings are no where near those that JTIS indicate to be correct even on the working side of the car.


I'd love to know if anybody has seen similar "pulsing" issues.


It's still a bit cold here to be working outside yet!! As I discovered last week when I blew the top radiator hose, £100 for the part and £85 to get the car 3 miles home (automatic).


Regards.


Jon

 

Hang in there and keep us posted. Here's hoping you'll get a stretch of warmer weather so you can finally nail it down....
