Cleaned wheel sensors, soldered ABS module. Still has ABS, Traction unavailable :(
#21
OP here, finally got around and had the Jag shop read the proper C codes.
The following codes were read with the ABS/TRAC issue that's been going on with the XK8:
C1233, LEFT WHEEL SPEED SENSOR
C1145, WHEEL SPEED FRONT RIGHT
C1234, FRONT RIGHT WHEEL SPEED SENSOR
C1095, PUMP MOTOR CIRCUIT
So what's the pump motor circuit? Would the pump motor circuit cause the other codes to fire?
Thanks.

the 1095 is classic indicator code that it needs rebuilt, the other sensor codes may or may not be related. Last time I helped with a bad abs module, only the C1095 code was there. You may have both a bad ABS and some wiring/harness issues.
First, I'd send off the module for repair,then see if the sensor codes return and proceed accordingly.

I'll PM you.
The guy @ Automotive Scientific said they rebuild Jag modules all the time. When I mentioned that my daily driver were Lexus', he said he cannot remember ever rebuilding an ABS module on any Lexus product. He's seen a few ECU's, however. I guess some companies use better components than others.
Jaguars were just a little ahead of their time in electronics. Too bad they didn't have time for their subcontactors to get the bugs out of their modules. What's worse is that no new, upgraded ABS modules were ever available at a fair price--and they continue to run owners' crazy.

My module says it was made in the Philippines. I didn't know the PI had any plants that made electronics that sophisticated, or that Jaguar.....oops....Jaguar/FORD would use their stuff. Question: Did the A.S. shop say they would fix your module even after it had been opened? We are reading that some shops will not touch ones that have been opened up. Maybe they don't want us to know how simple the repair really is, and that it is NOT a major job.

The Philippine semiconductors and electronics industry is the largest contributor to the country's manufacturing sector. In 2013, the industry accounted for 41% of total exports, brought in US$ 918 million-worth of foreign and domestic investments, and employed 2.2 million workers. The potential for the industry remains high, as member firms intend to move to higher value-added manufacturing to meet global demand. These companies plan to improve current production capacities, to expand current research and development and design capabilities, and to further develop the labor force over the next several years.

Thank you for your reply and info. I am trying to find owners who actually SOLVED their ABS/TCCM and now CEL issue. Jag Yi left us hanging, so I don't know if he solved it via the module rebuild or any other method....or not at all.
These horror stories seem to go on and on, worse when modules are replaced after "rebuilding". Some who do their own R&R and re-solder seem to have immediate success while others just keep going in circles with even MORE idiot lights flashing. That would be my case. If these modules are being "disconnected" from the CAN bus due to the broken solder joints to the ABS pump, and then showing NO connection after a re-solder and reinstall.....WTH is happening?
Because I am now getting the ridiculous "incorrect part installed" from my original module, I have to assume the whole system is either corrupted or badly programmed from Day 1. I also have no speedo or ODO. Otherwise, the car starts and runs and drives great.

After the hard reset and letting it sit for a day with the battery disconnected I started her up and VOILA! No more CEL! So, I drove it around our backwoods and small highways for at least 50 miles....all still with NO speedo or ODO, and the CEL stayed gone. The other flashing warnings stayed on, and the ABS light never went off. I parked in my driveway and shut it off. Started it up and the CEL and code were back. Tried multiple restarts and it persists. I ALSO NOW HAVE A BEEPING ALARM OF SOME KIND THAT STOPS AFTER i REMOVE THE KEY. WTH IS THAT??? I disconnected the battery again to check later. Battery read 12.86 V before initial restart.

Quick update. After leaving the battery disconnected overnight from a NON-CEL start yesterday, I hooked up and started the car to put it in the garage. Easy start, NO CEL, ABS light flashed and then stayed on, and NO BEEPING WHEN I REMOVED THE KEY. So, it sits awaiting my attention.

The most current update is that I pulled the module again and sent it to ModuleRepair Pro, inc. in Van Nuys, CA. It cost $100 for the repair, plus shipping both ways. After answering all my questions, they had it back in about a week with shipping both ways, I reinstalled it, and everything works as it should.....except now I have a power steering leak that will have to wait for better weather. I highly recommend the Module Repair Pro service.

Update: After having the ABS module repaired, everything was fine, but my PAS pump blew its seal. Worse job than R&R the module, but it got done. On the 3rd drive out to reset the emissions computers, I stupidly left my lights on for a bit while in a store, came out, cranked it up....and ALL the lights were back.
Went home, read codes (P1637, P1111(?)). P1111 just says the scan was complete. But it turns out the P1637 may indicate the ABS module has a problem, it is more of as "general" defect code that does not pinpoint the real problem. I guess there are so many ABS power contact issues it has become the "go to" repair. It seemd to fix mine, but one low battery start and I'm back where I was a year ago.
Gino at Module Repair Pros says the most likely failure now is the ECU. I've heard that it can be a CAN problem. So, I'll remove and inspect it tomorrow. The big issue is that most electronics in the 1990s are full of crappy capacitors and even mire crappy non-lead solder. We'll see what's happening inside the "box". At least it's easy to remove.
