Abs light on dash is lit brakes are good - 2001 Isuzu Trooper

Have you had the vehicle checked for DTC'S - diagnostic trouble codes ? I would start there first . Battery , charging system all good ? What computer , the ABS has a control module all to it self . The Air con has a relay in the under hood fuse box controlled by the PCM / engine computer . If there is a problem with ABS , The EBCM - electronic brake control module will turn on ABS and the red brake light .
A low voltage condition could cause this problem , but I would expect more of the lights to be lit on the dash . Including the check engine light , battery light . This are not connected , Power or ground wise . Have the vehicle checked for codes , that should be the first place to start any diagnostic's always !

It is in the under hood fuse box ABS 60amp ! An one in the instrument panel fuse box .BRAKE fuse 10amp .

Fuse Block - I/P
Left side of I/P behind access panel , open left door there is a access panel at the end of dash ! Hope i explained that good enough !
Now then what kind of problem are you having ? Maybe I can help ! ABS light lit on the dash , or maybe it doesn't light at all ?

Possibly a defective ABS sensor, or low brake fluid. Recommend a reputable mechanic to assess the issue.

abs light means u have a problem with one or more abs sensors located on the each wheel bearring or it can be one of the wheel bearring,brake light means u have to replace the emergency brakes and traction off can be a fault with the abs sensors or the abs pump but u can go to auto zone or any autoparts where tey can scan ur car for free

this may sound crazy but change the bulbs in the light that is up by spoiler and im sure the lights in dash will go off. the dash light and the rear spoiler light use the same ground. let me no if it worked or not.

ABS & brake light lit on the instrument cluster ? DTC'S - diagnostic trouble codes stored in the EBCM - electronic brake control module . Your best bet ,take it to a qualified repair shop .

replaced brake light switch under dash, if you don't know how to test don't do anything !

there is most likely a fault in the abs unit or the sensor. It will have to be pu on a computer to be diagnosed.

make sure u didnt break a wire, there are sensors on the brakes, make sure theyre plugged in

yes you need to have the abs system checked out...i had a suburban that did that and ended up losing my brakes.so yes be concerned.

The only way to know axactly what happen is with a diagnostic computer.
Because the ABS use a Speed sensor on each of the wheels.
Hydraulic selenoids on the ABS box or Module..
If the light is on. its mean the Anti Lock Brake System is inactive., You gonna brake like any car with no ABS.
I hope this information work for you.
