Odometer

The OSS produces maximum of 5000 readable pulses/mile between 5 and 161 km/h (3-120 mph), which are sent to the ECM to determine vehicle speed. The vehicle speed input is used to determine the miles the vehicle has traveled. The ECM reads the OSS signal and sends vehicle speed information to the BCM over the CAN bus. The BCM in turn calculates the distance traveled and sends the information to the I/P cluster over the Class II link. The I/P cluster increments the electronic odometer accordingly.
