2004 Chevrolet Blazer ZR2 6 Cyl 4.3L
ABS & brake lights on but not consistantly, brake system function is normal & brake fluid level is full. Any ideas?
Both the ABS and brake lights come on at the same time, but not always on. No consistancy, sometimes they don't come on for days. Sometimes stay on for days and other times just until the key is turned off and back on.
Read the ABS code stored. There is a code stored that will isolate the reason. You will need an appropriate scanner to read them. This is where the diagnostic process begins. No other way.
