When the Powertrain Control Module (PCM) recognizes Brake Switch No. 2 voltage is not equal to the applied value at the PCM when Brake Switch No. 1 is applied. This could be a normal condition. If this condition is seen repeatedly by the PCM the fault is set. Cruise will not work for the rest of the key cycle.
