The power brake assist may be tested by checking to see if brake application requires less effort with the engine (6007) running. If the effort is the same with or without the engine running, isolate the problem using the diagnostic test procedures in this section. Refer to Pinpoint Test K, Pinpoint Test N, Pinpoint Test P and Pinpoint Test Q.
