I had the same problem. Disconnecting the battery is a temporary solution. To fix it for good, you need to access the CJB (Central Junction Box) in the rear trunk. It is located on the right hand side of the trunk. You must remove the fabric liner. Once you have access to the CJB (box right above the battery with the 3 big relays), disconnect the positive from the battery. There are two connectors close to the floor (lower portion of the CJB). One is brown and one is purple. The problem is with the brown one. Since you are there, fix both of them! Disconnect them. Wwhen disconnecting the purple one, the parking lights will turn on (this is ok). Rub your finger on the connectors, you will feel moisture. Use a hair dryer or a heat gun and dry them. You will see some corrosion on the pins (CJB). I used a file to remove the corrosion. I also used a tiny screwdriver (used to fix watches) to scrape the female pins inside the connectors. Once completed, plug them back and reconnect the battery. Try the hazards by pressing the console button. If not working properly, repeat the file and tiny screwdriver steps. Once everything is ok, disconnect the two connectors (brown and purple) and add dielectric grease to the connectors. Plug them back and you should be good to go!

HI transponder is chip in key, remotes talk to door module. new remotes can only be added with software like Jaguar ids/sdd you cannot add remotes with any other procedure by pressing buttons or switching keys all post 2002 s-type are like this should of been programmed to the car when the key (transponder chip in key) was coded to the car cheers Joe

This happened to me today, hazards came on several times whilst driving. Only short-term remedy was pulling over & switching ignition off. Also, Eco stop-start has stopped working simultaneous to the hazard problem. I assume they are related faults.

Hi Mark Thanks for letting us know what the problem was...and how it was rectified. Very useful for future reference! With the amount of rain we have had just recently I'm not surprised its found its way into everywhere. Regards Trevor

Hi Trevor. It was a water leak travelling across some cross section into the rear junction/relay box (in the boot) causing corrosion on the contacts. They had to fix the problem where the water was coming in and replace the relay box. seems ok now fingers crossed. Got the impression from the Jaguar Assist guy I phoned when this first happened, that he new what this fault was before he even saw the car. so he must have come across it before. mark.
