Abs warning light on - 2002 Jaguar S-Type

Today, most new vehicles come with either an ABS or a traction control system. A problem in the ABS or traction control system is usually indicated by a warning light. When the ABS warning light is on, it means that the ABS has been shut down because of a mechanical or electrical failure.

Looks like you have a few issues there.

1. The battery warning. This is indicative of a weak battery and if your battery is 3 years old or more I would replace it.

2. If you have a weak battery this can trigger other warning lights in the vehicle, typically the ABS warning but sometimes other warning lights as well depending on the electronic features in the car. If you replace the battery this should correct the battery warning and most likely the ABS warning if both of these warnings appeared at the same time.
Normally, once the ABS warning is displayed the anti lock braking system(ABS) will be shut down. Whilst your braking will be normal, if you brake too hard and lock up your wheels on a slippery road there is no ABS assist to prevent the brake lock up which you have when the system is working.

3. If the alternator on the engine is not generating sufficient power and thus not charging the battery at all, or very little, you will likely get a battery warning light. I don't know if your 1999 vehicle has a warning light to indicate a faulty alternator or not.

4. Check Engine Light.
You suggested the CE warning has been showing up for a few days and before the battery and ABS warnings popped up.
The CE warning can be caused by dozens of different engine issues.
The vehicle needs to be scanned with the appropriate scan tool to see what fault codes the onboard computer is generating because if you have a CE warning light there will be fault codes generated 99% of the time.

Once these fault codes have been pulled the mechanic can start to diagnose the cause of the problem or problems. Each engine fault code your car's computer is generating can be caused by different types of problems so it is important that they diagnose the issues correctly. Otherwise your Check Engine light will remain on as long as the causes are not identified and fixed.

CLOCKSPRING

On vehicles equipped with antilock brakes (ABS), a second warning light is provided to warn if a problem occurs within the ABS system. The ABS lamp comes on when the ignition is turned on for a bulb check, then goes out after the engine starts. If the ABS warning light remains on or comes on while driving, it indicates a fault has occurred in the ABS system.

What happens next depends on the nature of the fault. On most applications, the ABS system disables itself if the ABS warning light comes on and remains on.

On occasion an ABS light will come on when a brake light is out. So check your brake lights first. Your ABS light is on because there is a malfunction in the ABS system. Is your brake warning light and your ABS warning light both on? This would be an indicator of a major malfunction in the ABS system. Stop driving the vehicle and fix this immemorially. If only your ABS light warning light is on this will not effect normal braking but the ABS system is disabled while the ABS warning light is on. You still need to have it repaired but you still have brakes for the moment. Now the code for this fault will be stored inside the ABS memory module. So you pinpoint this with scanner. Hope this helps

probally not have wheel bearing checked....hope it helps

brake pulsation is caused by warped brake rotors, not sure the ABS light and the pulsation are related, The ABS warning light requires a scanner to be connected and to read the fault code that is stored when the ABS warning light is turned on.
