P1380 Saturn DescriptionThe Powertrain Control Module (PCM) receives rough road information from the Electronic Brake Control Module (EBCM) on the serial data circuit. The PCM uses the rough road information in order to enhance the misfire diagnostic by distinguishing crankshaft speed variations caused by driving on rough road surfaces from the variations caused by true misfires. The EBCM transmits rough road information based on the inputs from the wheel speed sensors.
