I am sorry, thought it was airbag.
Ok, the abs light comes on when it detects a fault in the abs system. This can range from faulty wheel speed sensor in one of the 4 wheels, wiring issue, or abs control module. The other lights are on due to the abs light being on, as these all tie in to the abs system.
All shops I know of are equipped with a diagnostic scanner with ABS capability to read the ABS control module for stored fault codes. Diagnostic time should be 1 hour labor.
Repair costs range from less than $100 for wiring issue, $250-300 for faulty wheel speed sensor, to $750 -800 for control module or hydraulic unit.
Based upon your description, I suspect either a faulty control module or wiring harness issue.
Again, sorry for misreading it
