Test D28 - Closed Brake Sensor Switch

Ensure Orange/Light Green wire is located at pin No. 9 on 60-pin and is not damaged. Start engine. Depress brake pedal firmly to floor and hold. Using an ohmmeter, check resistance between Orange/Light Green wire at No. 9 and Black wire at pin No. 60 on 60-pin connector. If resistance is 1000 ohms or more, go to TEST D29  . If resistance is less than 10 ohms, replace PRC module.
