Abstract
A system for performing diagnostic checks on a data message transmitted from a sensor and received by a receiver includes a receiver clock tick counter, a prescaler counter, a calibration pulse detector, a nibble counter, and a calculator. The system receives first and second data messages transmitted from the sensor. Pulse widths of first and second calibration pulses of the first and second data messages, respectively, and lengths of the first and second data messages are measured using the receiver clock tick, prescaler, and nibble counters based on a compensated receiver clock signal. Thereafter, the pulse widths of the first and second calibration pulses and the lengths of the first and second data messages are compared using the calculator to perform the diagnostic checks.
