Jaguar XJ6 - Recent Questions, Troubleshooting & Support

the neutral safety switch maybe out on the car

Question moved from 'Edge Computers'. It could be that the compressor itself is failing. It could be the electronic clutch on the unit. It could be the belt slipping if it makes a loud unnatural squealing noise. That is very low mileage at nearly 13 thousand miles, but as a 1994, the AC may need refrigerant gas.

See if the videos and articles help. First one says is needs a calibration tool. https://www.google.com/search?q=2003+Jaguar+XJ6.+How+can+I+equalise+and+reset+air+suspension+and+ride+height+after+fitting+a+new+sensor ..

sounds like you got the float stuck when you installed the new part, have seen this hapeen often

Charge the battery with an external charger for about 6 hours, then start the engine and measure the battery voltage with the engine running. It should measure 13.5 volts or more. If it reads 12.6 or less volts, then the alternator is not recharging the battery. Take the car to Autozone or similar business for a free check out of the alternator and voltage regulator. They will be happy to sell you any needed parts. Hope this helps!

Try gently moving the shifter around while cranking the engine (while in the park position). There is a sensor in the J-shift that will prevent the proper voltage from reaching the main computer if it is out of adjustment. This problem drove me nuts until I figured it out. I would start and run fine, then it was like the fuel pump went out. Good Luck (I know it's an old post but it might help someone)

I had the same problem! All you do is call your closest Jaguar dealer and give them the serial # that is under the radio(so you have to remove the radio) they did it over the phone for me and they will give you the code, it's usually gonna be a 1- 6 combo cause thats the numbers for programming if you notice.

Yes sir! https://www.google.com/search?q=1993+Jaguar+Xj6%2C+4.0L+Firing+Order&tbm=isch&ved=2ahUKEwikk5Kz_NTyAhXvnnIEHecIBFMQ2-cCegQIABAA&oq=1993+Jaguar+Xj6%2C+4.0L+Firing+Order&gs_lcp=CgNpbWcQA1CRdFjjpgFg568BaABwAHgAgAFpiAGKBZIBAzUuMpgBAKABAaoBC2d3cy13aXotaW1nwAEB&sclient=img&ei=VNQqYaSZF--9ytMP55GQmAU&bih=937&biw=1920&rlz=1C1QJDB_enCA643CA644 ..

Great radio

Many cars of that period could be reset by some ignition key sequence.
Try switching from the off position to the on (not start) several times within 15-30 seconds.
It won't hurt anything and might turn off the light.
If the problem is still present that caused the light to go on the first time, it will likely come on again after you start the engine.

I hope the reason for that alarm light has been since corrected.

Some cars needed to have the battery disconnected for several minutes to cancel the memory contents.
Newer cars will not likely respnd to that since flash memory is now common which retains the error code even without power.

check your fuses and module that control those function on the vehicle

Lock your doors with key and hold until the alarm activates, then unluck car and start

The 1995 Jaguar XJ6 is OBDII compliant. You can read engine codes using an aftermarket code reader. You may have to call it a 1996 in order for the tool to read the codes. What you can not read without Jaguar's own reader is the ABS codes. Good luck!

Reset yes, just lock and unlock the driver door with the key. Turned off no.

there are 2 large terminal plugs with the wiring for all the instruments that are plugged into the back of that panel. make sure they are snug and in place. You reach in and under but it may easier to "simply" remove the cluster. 4 screws hold it in place accessible form underneath and with a long phillips screwdriver and lighting.
