Vehicle keeps going. it will stop if put in neutral. Can hear the abs engaging.
Check brake pads for thickness and discs for condition (both sides). Have it taken to an accredited brake shop for a full evalution of why the system has failed.

your master cylinder is gone. when stopped apply pedal and hold let up slightly then reapply if pedal sinks to floor master is bad.

I had it repaired: one of my sensors needed to be replaced. No more light!
SOURCE: Were is my ABS sensor located on my 2000 Isuzu Rodeo
there should be a sensor at all 4 wheels so make sure there all pluged in

Hi.
If problem is only on startup and when idleing, then the problem is likely IAC system, also a vacuum leak will cause the same problem.
If problem is not only on startup and idle, but also when driving, then MAP sensor and EGR system must be checked.
Check also accelerator cable state and setting.
The first thing to do is pulling out the OBDII fault codes stored in the ECM. This is done connecting a code reader to the ECM diagnostic port. The job can be done for a small fee at any local garage, and it is done for free at AutoZone.
The codes will help locating the problem.
About possible faults:
Problem is stalling when idling and during startup, but engine idling fast all the time. Problem not starting at times it is due to the fact that the wrong mixture is being sprayed, this is probably causing flooding and misfire. Since the CEL is on, one of the codes returned is probably misfire.
Check accelerator.
Check IAC system. This is composed by a valve and a solenoid that check and control amount of extra air air when the engine is idling. The IAC valve is located on top of the throttle body.
Check the vacuum system and try cranking with gas tank cap off. Vacuum
system is tested using an hand tool gauge onvacuum lines while spraying
card cleaner on the hoses (or heating them with a torch). If there is a
leak, pressure will go up. A big leak will also do hissing noise, and
will often result in a lean code when doing an OBD code scanning.
This kind of symptoms can also be caused by weak wiring to MAP/MAF sensor (MAP in this engine).
If the car also drives very rough and is revving up and down in a weird way, check the EGR valve.
As first thing I would do a code scanning. This car is OBDII. The scan can be done for free at the nearest Autozone, or for a small fee at any garage.
If you get any OBDII code from the scan, report it here, so that we can individuate the possible reason for the problem.
If you repute my solution helpful, then please take some times to accept the solution. Providing good repair tips requires time and skills, and your feedback is important for us.
Regards.

I forgot to add the most crucial bit of info... this inability to stop only happens on snow covered roads.
the abs is doing the job it is designed to do and that bis to give you directional steering by stopping the wheels from skidding. On snow/ice covered roads it is up to you to assists the brakes by using chains on the tyres or those special spiked tyres
Not allowed on Wisconsin roads
it is obvious that there are tyres that will be allowed on the roads that will give traction on ice and snow so talk with a tyre dealer and be guided by their advice
