SOURCE: Warning Lights on dash: ABS, BRAKE,STOP,CHECK MANUAL

your abs unit is failing and needs replaced ...the procedure for testing is to backprobe green wire in abs connector and watch voltage wave pattern on a scope ....it will show voltage does not go from 0 to 12 but only 4 to 12 volts that verifies problem is abs controller.

SOURCE: I have an emission workshop warning. For no

Stop by a local parts store like an Autozone, Advance, etc.. and have them do an OBII scan for you. (they do it for free) The scan will show all faults and give you answers to all possible problems instead of jusr throwing parts at it. They can reset all your lights also.

I have a '99 dodge grand caravan se, while in park the abs light came on, the battery light came on, and the check engine light has been on,


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.

01 passat, 02 sensor means? it drives fine except Always various different warning lights on.


Need to replace the Oxygen sensor on the exhaust. This is a maintenance issue, every modern car will eventually need this to be done. Not very difficult or technical, so not necessary to be ripped off by dealer, find a cheaper mechanic.

The ABS lite, No Trac Lite and Service engine lite keep coming on


When the Service engine soon, ABS and TRAC lights are turned on at the same time the computer control units for the engine and the ABS/TRAC systems has sensed a fault in the electronic controls of the engine and/or the emission system and the ABS and Traction Control system (part of the ABS system). When this happens you will seldom feel the car engine run any different or the car drive any different. There are about 200 possible faults that turn the Check Engine light on, the fault in your car is likely a part called the VSS sensor to know for sure what the problem is you must have the system tested; Kragen and Autozone parts stores do this testing for free

The abs light stays on? And will this affect emissions?


Abs light will not effect your emissions and will not fail your emission test either.

My service traction system warning light is on. What causes it? My ABS warning light remains on at all times. What causes it? My low coolant level warning light comes on often. The expansion bottle is...


Most traction systems have sensors at each wheel. These detect wheel spin (can be a loose connection, broken wire, dirty sensor) The ABS won't work for the same reason but your brakes will work fine without ABS. (as long as brake fluid is full) The expansion bottle should have some coolant in it as well as the radiator. My experience is the bottle has a low level sensor that can get dirty ( If it was full) But you seem to be losing coolant? Is the lid on tight? Do you ever see coolant on the ground or in the engine bay? Sorry that's a mystery from here. Hopefully it is not disappearing in your engine. That would be a bad head gasket!

Emmissions light has come on?


you need to get it scanned, i assume "emissions light" is your check engine light, or the "visit emissions workshop" message, which means, go to a shop and get it checked. The coolant disappearing means you probably have a leak. Another reason to check it,

ABS and coolant are unrelated unless there is a problem with the ECM (engine control module) or instrument panel. Is the red coolant warning sign for coolant level or temperature?

With ABS if there is any failure with any brake electronic component (sensor, motor, or fluid level etc) the ABS will shut down completely and flash the light. If the light is on or flashing the ABS is non functioning.

I need better information on the coolant and ABS to give better information.
