Default Hard Reset

Do this works also for the S-type?:
notice that the NEGATIVE cable will make contact with the POSITIVE terminal:

(from BRUTAL)
TO DO A HARD REBOOT YOU HAVE TO DISCHARGE THE CAPACITORS IN THE ECU(ALL ECUS) AND TO CORRECTLY DISCHARGE A CAPACITOR WHICH IS NOTHING MORE THAN A BATTERY YOU HAVE TO GIVE IT A PATH TO GROUND. TO DO THAT DISCONNECT THE NEGATIVE BATTERY TERMINAL FROM THE BATTERY AND MOMENTARILY TOUCH IT TO THE STILL CONNECTED POSITIVE, THIS GIVES ALL THE CAPACITORS A PATH TO GROUND AND WITH ERASES ALL VOLATILE MEMORY.

Tried last night, it didn't work, I guess it's I'll check the sensors. Anyway, this is the whole story: The car has been sitting in my garage for almost a year, due to a legal matter with the shop that repaired the gearbox (long story) I warmed the car about once a week without any problems. The day before I finally took the car to the shop to re-repair the gearbox, the car wouldn't start due to a discharged battery so I had to jump-started it. It was then when the Traction Control Malfunction light came on along with the ABS one. After I got the car back, (I guess the shop had to jump-start the car again) the lights were still one and I knew that the battery needed replacement. I replaced the battery but the light were still on.

a hard reset is not to clear check engine, abs srs, lights etc....those are retain in NON volatile memory, youre only clearing volatile memory when you do a hard reset

I understand, just that I though the Traction Control Malfunction message in the Message Center was in the volatile memory and the problem was when the battery died thus after replacing the battery I needed to to a reset. Thanks a lot.

You can buy cheap scanners to read and clear your own codes though

I do have a pretty good scanner that I used before but it only works when the check engine light is on, when the message center displays a malfunction it doesn't read any codes.

Yeah thats true on chassis codes or jag specific, do you know a tech at the dealer you visit? I work with alot of customers no longer in warranty to do easy stuff and fast diag to let them know what theyre looking at. 2 fold so they dont go to someone who doesnt know jags, and to keep it affordable within reason to own. So in other owrds i would just go to the drive, pull the codes and let them know if i need to look at more indepth or give an est, and let em go. I dont like being look at as a reason the public think dealers are *******s. I meen no one calls the cardiologist a theif cause he's a specialist and charges alot more than a general practioner. Who do you want doing your heart diag, gen. Or spec????

Yeah, you are right. Although I'm not a mechanic, I do try to do all the work myself, not only save to some money but I also enjoy it. Down here in Puerto Rico, we only have one dealer so you can imagine how expensive it could be. Anyway, thanks for your advice and your time. By the way, nice 4x4, here is a picture of my trail rig: (The Samurai)
