Slot Obd2

1. OBD 2 is an abbreviation of On-Board Diagnostics and refers to the automotive electronic system that provides vehicle self-diagnosis and reporting capabilities for repair technicians to access subsystem information for the purpose of performance monitoring and repair.
2. So I Down loaded the Free Subaru Logger, the OBD-II to serial connector (Came with AccessPort), and I have a laptop (Under repair so I have yet to use them.) So when using AccessPort having that cable between my legs is just annoying (using the live boost option), and will be even more annoying when I have a laptop connected to it.
3. Hoping someone can help me here. The CEL on my 2000 Forester keeps going on and off at random times. I think it's probably the rear O2 sensor. I purchased a OBD-II scanner/reader to check it out, but I'm having a hard time seeing where to plug it in under the dash (it's probably staring me in.

Does My Car Have OBD-II?

Empty Slot (Civic Plug) Integra FLR - (Fuel Pump Relay) Green / Yellow. Empty Slot (Integra Plug) Civic FLR - (Fuel Pump Relay) Green / Yellow. ACC - (A/C Clutch Relay) Black / Red.

All cars and light trucks built and sold in the United States after January 1, 1996 were required to be OBD II equipped. In general, this means all 1996 model year cars and light trucks are compliant, even if built in late 1995.

Two factors will show if your vehicle is definitely OBD II equipped:
1) There will be an OBD II connector as shown below, and
2) There will be a note on a sticker or nameplate under the hood: 'OBD II compliant'.

The Connector

Pin 2 - J1850 Bus+
Pin 4 - Chassis Ground
Pin 5 - Signal Ground
Pin 6 - CAN High (J-2284)
Pin 7 - ISO 9141-2 K Line
Pin 10 - J1850 Bus
Pin 14 - CAN Low (J-2284)
Pin 15 - ISO 9141-2 L Line
Pin 16 - Battery Power

Where is the connector located?

The connector must be located within three feet of the driver and must not require any tools to be revealed. Look under the dash and behind ashtrays.

The Five Flavors of OBD II

While the parameters, or readings, required by OBD II regulations are uniform, the auto manufacturers had some latitude in the communications protocol they used to transmit those readings to scanners. Naturally, each felt they had the one true way, so we have five different OBD II communications protocols in use.

The big scanner consoles costing thousands of dollars include the decoding software and firmware for all five protocols in their units, making them universal. Less expensive units, for home or small shop use, are usually customized for a specific communications protocol. Be sure the scanner you are using suits the protocol of your car.

As a rule of thumb, GM cars and light trucks use SAE J1850 VPW (Variable Pulse Width Modulation). Chrysler products and all European and most Asian imports use ISO 9141 or KWP2000 circuitry. Fords use SAE J1850 PWM (Pulse Width Modulation) communication patterns. All 2008 and newer model year vehicles use CAN.

There are some variations among captive imports such as the Cadillac Catera, a German Opel derivative, which uses the European ISO 9141 protocol. If you have first hand knowledge of other such variations, please send them in and, together, we can build a more complete listing.

On 1996 and later vehicles, you can tell which protocol is used by examining the OBD II connector:

• J1850 VPW --The connector should have metallic contacts in pins 2, 4, 5, and 16, but not 10.
• ISO 9141-2/KWP2000 --The connector should have metallic contacts in pins 4, 5, 7, 15, and 16.
• J1850 PWM --The connector should have metallic contacts in pins 2, 4, 5, 10, and 16.
• CAN --The connector should have metallic contacts in pins 4, 5, 6, 14 and 16.

If your vehicle has this style connector, but doesn't have these pins populated, you probably have a pre-OBDII vehicle. To add some confusion, even having the connector with the contacts shown above is not a guarantee of OBD II compliance. This style connector has been seen on some pre-1996 vehicles which were not OBD II compliant.

Information on Pre-96 Cars

A reader with the California Air Resouces Board provided this list of pre-96 OBD II engine designations. Note that CARB recognizes engine series, rather than vehicle models, so the engine designations are the true key, with the vehicle models provided as a courtesy.

California Air Resources Board List of
Certified OBD II Complying Engine Families and Models

A note accompanying this list indicated that certification is for the engine group only. The models listed are believed correct, but the engine is the deciding factor.

What is an OBD-II Connector?

OBD stands for Onboard Built-in Diagnosis. As the name suggests it is a diagnosis system that is built into all modern cars (after 1996) which has a computer based application that monitors the performance of your car through your speed, mileage, fuel emission data etc.. Apart from this it also measures some of the important vital parameters of an Engine. This complete system is called as an ECU (Engine Control Unit).

This OBD connector is meant to be used only by the service guy to monitor the health of your Car and provide diagnosis. Apart from this it is also controls the warning lights on your Cars dashboard.

How to use the OBD-II connector with Arduino/Raspberry Pi?

It is a federal law to modify or tamper with the OBD system of your car, but if your engine failure light has gone in your Car and you want to diagnose the problem by yourself then it is pretty much easy to use connectors like ODB-II to connect between your Car and a microcontroller or microprocessor. Once you get all the vital details of your car into a development platform like Arduino or Raspberry Pi then the application is limitless.

The OBD port can found on the dashboard near the steering wheel of every car. The position of the port varies based on the manufacturer and is normally hidden in a blind spot for aesthetic reasons. Once you find the port hook up the connector and connect the other end to STN1110 OBD UART board. Then the UART board is connected to a computer where the communication takes place through the Tx, Rx and Ground pins and normal data type will be with 9600 baud rate in which there will be 8-data bits and 1 stop bit with no parity. We can then use any serial communication software like putty or even Arduino to speak with the car though AT commands. Each AT command has a specific task to perform or returns a specific value. You can learn more about interfacing through the sparkfun hookup tutorial which explains how the connection should be made and initiated.
