Overview
Overview
The CB7 is designed to read vehicle speed and engine speed data from Ford vehicles equipped with SCP Bus. The Bus is sometimes referred to as J1850 PWM. It therfore will work on virtually all Ford vehicles that have the 16-pin OBD-II connector. It also covers early versions of the Jaguar S-type.
