How to Retrieve RABS Trouble Codes for a 1992 Ford F-150
You can retrieve the rear anti-lock brake system (RABS) trouble codes from your 1992 Ford F-150 from home using an OBD I scan tool. This tool can be purchased from most auto parts stores or from your dealership. The On-Board Diagnostics computer receives and stores RABS error or trouble codes sent to it from the anti-lock braking system. Sensors in the braking system detect malfunctions and send diagnostic trouble codes to the computer. The computer, in turn, illuminates the ABS light on your instrument cluster. You can read the codes with an OBD I scan tool so that you can troubleshoot the problem. You can also use the tool to reset the computer and turn off the ABS light after repairs have been made.
