The CP9550 Pocket Scan Plus is a CAN (controller area network) compliant diagnostic code reader that utilizes the standard 16 pin OBD 22 connector which is permanently attached to the unit.

The CAN functionality allows the auto code reader to interact with all the diagnostic sub-systems in the vehicle to provide freeze frame data. This essentially involves taking a snapshot of the overall sensor readings from the cars’ CPU at the time an MIL event is taking place (this is the point at which the dreaded “check engine” light comes on.

To read error codes from your vehicle, simply connect the OBD II cable to your cars’ DLC (data link connector). This OBD II compliant input port is normally located beneath the dashboard.
