After reading the question for: "circuit 1 failure" I decided to post my experience with the related "circuit 2 Failure" read on:
On the dash there was a "circuit 2 failure message on my 1988 XJ40 or XJ6. After some poking around I noticed that the fuse for the Auxiliary Electric Fan on the radiator up front was blown. I replaced it, but after another drive was blown again. Some more poking around turned out that the Fan was in a rather sorry state of rust and barely turning thus creating a short and melting the fuse as soon as the relay will try to turn the circuit on. The fuse is not really labeled properly (and I don't really remember right now what position it was) However it is controlling the AC relay and all that grouping, Fan relay also. Checked the wires and fuse socket for signs of melting from somebody that might have put a higher amp fuse but found no problems. So I got a nice new looking Fan from the junkyard and the problem dissapeared and never I have seen it again...
The car had many electrical problems to the point that the Electronic display was starting to look like a Christmas tree dispaly, flashing through various varnings and driving me nuts. With patience and using the info I have found on the web I have eliminated them all, except for a bulb failure warning that is really for real and legitimate (I am missing the light on the rear left bumper corner) Strangely enough the warning goes away sometimes for hours at a time...
I don't own the original manual that came with the car, howver I think I have just about all documentation that is available for the XJ40 cars plus all the info on the web but nowhere there is any reference to any of the misterious "circuit n failure" warnings... All the other were somewhat clearer: (ABS) and so forth but these were a puzzle.Hope this helps somebody Cheers!!!
Reply from Olen1009...I just bought an '89 XJ6 with a circuit 2 failure and, assuming the manuals are similar, the original manual wouldn't help you. There is nothing in it about fuses except the locations of the 3 fuse panels. Period!
well fist of all the xjs is a two door V-12 and the xj40 is a four door. also the xj40 was supposed to be a newer and better xj6 but in my opinion the xj40 with those square headlights and boxy look is one of the ugliest jaguars ever built. "just not a looker" there made in different years.
The 1988 Jaguar XJ40 3.6L is typically equipped with a 4-speed automatic transmission (AW30-40LE). Other transmissions that could potentially fit include the ZF 4HP22, which was used in some other Jaguar models of that era. However, modifications may be necessary for proper fitment and compatibility with the engine and electronic controls. It's essential to consult with a specialist for specific compatibility and installation considerations.
The same place it is on a 1988. RH side of engine. If you cannot get original service manuals for your car, for whatever reason, get the Haynes for XJ40 through 1994. The procedure and engine layout are identical. Mark
60 nm or 44 pounds then give it 90degree turn
On a Jaguar XJ40, the pollen filters are located behind the glove compartment. To access them, you will need to remove the glove compartment by unscrewing a few screws. Once the glove compartment is out, you should be able to see the pollen filters.
To press out control arm bushings you will need a machine shop. These parts are highly specialized and need to be to exact specifications.
To access the gear interlock solenoid on a Jaguar XJ40, first, disconnect the vehicle's battery for safety. Then, remove the center console by carefully unscrewing and lifting it out, which will expose the gear selector mechanism. The solenoid is typically located near the gear shifter assembly; look for a small cylindrical component connected to the linkage. Once located, you can disconnect the wiring and remove the solenoid for inspection or replacement.
To check out the master window switch on a Jaguar XJ40, first remove the switch panel by gently prying it up with a trim tool or your fingers. Inspect the switch for any visible damage or corrosion, and use a multimeter to test continuity across the switch terminals when pressed. If necessary, clean the contacts with electrical cleaner or replace the switch if it's faulty. Reassemble the panel securely once testing is complete.
XJ40 door handles are made out of a very brittle metal that breaks easily. On the inside of the handle is a protruding arm into which is inserted a rod that is pushed down to release the latch when you pull up on the handle. The arm on your door handles is broken. You can buy rear handles on Ebay. Take care to get the proper year. 1988-1990 handles are smaller than 1991-1994 handles. The good news is that the rear handles are interchangable left to right, as they have the little arms at both sides of the handle. Kids and ham-handed buffoons do not mix well with XJ40 door handles.
Remove the headlamps and front bumper. Remove the three upper retaining bolts and the wheel arch liner. Remove all the bolts holding the wing in place and remove it.
i don't know, but if you find out please tell me. My 1990 Sovereign has been in limp-home mode for 26,000 miles now
I have found that a fuse was out on the right side kick panel. Once the fuse was replaced the failure warning went out.On the dash there was a "circuit 2 failure message on my 1988 XJ40 or XJ6.

It burn because of a short circuit in the central consol it is one of the two cigar (under it the mass touch the +) Disconect it removing the center panel consol (it is under the "allume cigar")
