ABS light is on and remains on - 1998 Ford Expedition

The ABS warning light is on because the control module for the ABS has sensed a fault, until the fault is repaired the light will remain on and you have no ABS brakes. You need the ABS system scanned for the fault code to see what part or wiring is defective. When the system is repaired the light will go out.

The abs light is not part of the obd2 system. It can't be cleared. The problem must be corrected to turn ir off. Pulling the fuse will allow normal operation without abs capability and the light will remain on

The reason the system "growls" until the light comes on is that when the light is on, the system has determined there is a problem and disabled the system. The "growling" is the pump running. You can get a scanner that is able to access and scan the ABS module. This will give you a place to start.

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.

For a 1997 if you replaced the ABS unit that ABS unit detected a fault in the system you will need a scan tool that read ABS this is a enhance software that can read ABS codes

Have a code reader or scanner put on it. Most likely the code will point to a bad Wheel Speed Sensor.

The ABS sensor is a speed sensor also for Traction Control. This is why both lights are on , One of your front ABS sensors are bad or disconnected, or has a pinched wire.

If the ABS wheel speed sensor was defective and you replaced it, the ABS light will automatically turn off once the vehicle is driven. If the ABS light stays on, you still have another problem in the system.
If the light remains on, have the codes read and reply back with the codes and we can start diagnosing.
Regards,

check to see of you can get any faults from abs control module, if abs control module can not be scanned, check fuses, if fuses ok, it will need an abs control module.

Regarding the corolla abs light, you need to get your local dealer to diagnose the fault, it is possible a wheel sensor giving a faulty reading but while the abs light remains on you have no abs. Worth getting it looked at promptly
