Control Modules, XK8: Who can check and repair? by charlie193

Electrical problems in my '98 XK8, traceable to control modules. Who can bench check these modules to verify problems, then to repair as necessary? I don't want to replace good items as 'shot-gun' attempts to cure anomalies. Or, maybe there is a procedure for testing individual modules for functionality? I'm a capable electrical trouble-shooter and have good diagnostic equipment.

Turn Signal Malfunction by mchidiac

My mechanic put an aftermarket tail light on my 2005 Jag XK8. The right one works fine, but the left one, the rear turn signal does not "blink" although it sounds like it is blinking in the car very rapidly. Also, the tail light stays on constantly. We thought there was a short in the bulb socket, so we changed it out with a new one and it still did not cure the problem. We checked the relay module and put in a new one - still no fix. We put back the original tail lights and that did not work. The tail light stayed lit continuously on that one, too. We checked all of the fuses. They are all fine. When I put the key in the door and locked the car door, all the lights blinked like they should when the alarm is initiated, except the left tail light. The dealer said to try and reprogram the main computer and that should fix it. Does anyone have any opinion on this? Are we on the right track? As an FYI, the new tail lights are lower in voltage than the factory orginals and again, the right signal works just fine.

Convertible top problem by markas

A problem cropped up today in my 99 XK8 convertible. I was putting the top up and the latch went down before it grabbed the hook on the top. Now, the top will not go up or down nor will the back windows go up. I've tried the manual crank, but it doesn't do anything.
 
Any ideas about what to do, or is it a "go into the dealership" thing?

Stalling - electrical problem? by svp

My 2000 XK8 has a strange problem. 4 or 5 times a year, the car stalls while moving and then will not start. No clicking, no grinding, just nothing. But all the electrical stuff goes nuts -- steering wheel telescoping repeatedly, gas latch popping open, trunk and hood lids popping open. If I tow it home & let it sit for a couple of days, it starts again. It's been to the dealership several times. They said it was the gearbox & changed that. No help. Now they say they cannot find any problem. Does anybody know what is going on with this car? Thanks.

I finally took my car into the dealer and they said that the timing was off. The owner's manual said that you could open or close the roof up to 10 miles per hour. I was doing about 5 mph and that is when the timing issue happened. The mechanic said that just a tiny gust of wind could have prevented the hook from grabbing and pulling down the top. They acknowledged that the manual was wrong; you should be at a full stop.

I have the same problem on my XK8. Any idea what they did to sort out the problem at the dealership?

The problem was quite simple - the machanic had to luricate the hood latch closing mechansim that closes the roof. What happened was it the latch mechanism closed partially before the hood latched in, so he manually pushed the roof latch into the mechanism, then luricated the mechanism quite a bit. But this is the second time that I have a roof problem, so maybe I need the flush the fluid as many people had advised.
 
Hope this helps,
Tamir

Hi Tamir,
 
Thanks for the advise. My problem is that the roof is latching OK but the 'Convertible Latch Fail' message stays on and the rear windows don't go up. I am wondering where the latch sensor is located.
 
By the way, any idea as to how to flush the fluid?
 
Also, what sort of lubricant did the garage use and did they only lubricate the latch mechanism?
