Scanner LCD screenshot


Screenshot of the scanner display.

G: Shifted gear (actually I didn’t find this message yet just preserving the space)

S: Vehicle speed (km/h)

R: RPM (1/min)

C: Cruise state

P: Throttle pedal sensor (0-99%)

M: MAP-sensor, AP=atmospheric pressure (>96 kPa)

VS/VT: System and charging voltages (V)

TE/TB: Engine Coolant Temperature / Ambient Temperature (°C)

KM: Odometer / Tripmeter (km)

The display can manage multiple layouts.

Green LED: 5V power indicator,

Red LED: incoming message complete,

Orange LED (not showing): CRC OK,

Blue LED: CRC error.

New PCB layout for the scanner

ChryslerCCD_V120__10_final

Added SCI interface which connects the scanner directly to the ECU. The CCD-bus is more like a general network where all kind of information can be found but the SCI-bus is the place where all the diagnostics happen. The board can’t flash the ECU since it’s a bit complicated and not desired at the time. Besides there’s no more room on this PCB. There are external EEPROM memories available (2×512 kbit = 128 kB) to store information.

The image is generated with OSH Park’s internal renderer.

Edit: the boards are manufactured by PCBWay. I’m waiting for the shipment of 10 of these.
