A restraint control module is configured to communicate a sync pulse to a sensor. The control module includes a first sync pulse driver and a second sync pulse driver. The first sync pulse driver is connected to a first signal line and the second sync pulse driver connected to a second signal line. The first and second sync pulse drivers being configured to generate a differential sync pulse signal across the first signal line and second signal line using a first signal on the first signal line and a second signal on the second signal line.
