    Help again please.

    Some of you may have read my previous posts regarding a misfire in my early 2002 pre facelift 3 litre s type.
    I removed the inlet manifold and then due to circumstances beyond my control the job got abandoned for a period of six weeks ,replaced all spark plugs and the defective coil pack and inlet manifold gaskets, also renewed the top coolant hose as I managed to break the small nozzle that the return hose fits to,also the engine vent pipe which I discovered had a hole in the rubber elbow.
    Battery had gone flat while sitting inactive and found it would not take a chwrge
    ( Not sure if the battery is kaput or my charger has given up the ghost though it is making all the right noises) and battery is only two years old.
    Substituted the battery for one thought to be in good condition (it was in regular use)
    Fired up the car and it is running perfect however the low fuel light is on plus the
    ABS and DSC lights plus a DSC system fault warning
    Thought this was just the usual after disconnecting and connecting a battery and that it would reset itself after driving for a bit but no drove for a hundred miles(not all in one go) no change did a hard reset drove another sixty miles no change
    The ABS light comes on with the ignition and stays on when the engine is started
    the DSC light comes on with the ignition and goes out when you start the engine as it should at idle no DSC light or low fuel light although the message DSC system is still there, all well as you drive off but as soon ad you reach about twenty five miles an hour the DSC light and the low fuel light come on.
    Should add the tank is three quarters full and also there were no faults prior to the misfire and strip down.

    HELP!

    Low battery voltage is a common source of spurious faults popping up on S-types. There has been much discussion of this on the forum. I would suggest that you fully charge the battery, then turn the headlights on for 2-3 minutes (to dissipate the "surfce charge") and then take a reading with a digital volt meter, or DVM. Ideally you should have 12.6 volts, or more, indicated. If you have less than 12.2 volts, you can pretty much count on faults being indicated. Having the battery properly sorted is pretty much always the first step in troubleshooting electrical issues on these cars.

    Worst case read the codes to see what the car thinks is wrong.

    Yep... As a last resort!

    Only in desperation!

    Same as RTFM - Read The F(ine) Manual!

    If only it was so simple , i have a simple code reader but it only reads engine codes, took the car to place with state of the art diagnostics oh joy ! They spent an hour on it and could not get it to read my car.

    If you are keeping the car it's worth investing in an iCarSoft LR V2.0.

    It's the latest JLR specific OBDII code scanner and can read all modules in the car.

    Just at the moment, I wouldn't recommend that, my new LR V2.0 won't read any codes using the dedicated Jaguar software, but will find them using the generic OBD2/EOBD side of the scanner. Am in ongoing discussion with them to try to sort this, but not looking very good at the moment!
    I did post on this as a heads up to everyone, here is a link.

    I have the LR-II (and not the 2.0) which will read pretty much every module on the car. The i930 will reportedly do the same. Sorry to hear of your troubles, OW...

    As I said had it to a diagnostic place yesterday, they are supposedly able to diagnose all makes and models but are Land Rover specialists unable to connect to my car though they have done plenty Jags in the past .

    Fault is apparently in my car wiring ,strangely enough my cheap OBD code reader which originally diagnosed the misfire will no longer connect to the car
    Fault in the plug or the wiring to the ecu? Not much point in buying an expensive code reader if it can't find my car
    On a brighter note managed to get hold of a multi meter today and the reading across the terminals is just making 12.2 volts so hopefully that might be the problem though car starts first turn of the key

    Have ordered a new battery and see how we go from there
    Thanks for the help so far guys.

    When you receive the new battery you will be best advised to put it on charge as they rarely come fully charged.
