Where Is the Diagnostic Port on a Chrysler 300
Does My Car Have OBD-II?
All cars and easy trucks built and sold in the USA aft January 1, 1996 were required to be OBD II equipped. In the main, this means all 1996 modeling year cars and Inner Light trucks are tractable, even if built in belatedly 1995.
Ii factors will present if your vehicle is unquestionably OBD Two equipped:
1) There will be an OBD Two connector as shown below, and
2) There will be a note on a sticker operating room nameplate under the hood: "OBD II manipulable".
The Connector
Pin 2 - J1850 Autobus+
Pin 4 - Chassis Ground
Pin 5 - Signal Ground
PIN 6 - CAN High (J-2284)
Thole 7 - ISO 9141-2 K Blood line
Pin 10 - J1850 Bus
Pin 14 - Privy Depleted (J-2284)
Immobilize 15 - ISO 9141-2 L Line
Pin 16 - Battery Power
Where is the connector located?
The connector moldiness 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 Two
While the parameters, or readings, required aside OBD II regulations are uniform, the auto manufacturers had some latitude in the communications communications protocol they used to transmit those readings to scanners. Naturally, all 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 admit the decoding software and firmware for altogether five protocols in their units, making them universal. Less dear units, for home or small shop enjoyment, are usually customized for a taxonomic category communications protocol. Comprise sure the scanner you are exploitation suits the protocol of your car.
What Communications Protocol does my fomite habit?
American Samoa a rule of riffle, Gramme cars and light trucks use SAE J1850 VPW (Variable Pulse Width Modulation). Chrysler products and all European and most Asian imports employ ISO 9141 or KWP2000 circuitry. Fords use SAE J1850 PWM (Pulse Width Intonation) communicating patterns. Every 2008 and newer model year vehicles use CAN.
In that respect are just about variations among unfree imports such as the Cadillac Catera, a German Opel derived, which uses the European ISO 9141 protocol. If you have basic hand knowledge of other such variations, please direct them in and, together, we can build a more complete list.
On 1996 and later vehicles, you can tell which protocol is utilised away examining the OBD II connector:
- J1850 VPW --The connexion should have metallic contacts in pins 2, 4, 5, and 16, just not 10.
- ISO 9141-2/KWP2000 --The connector should own metallic contacts in pins 4, 5, 7, 15, and 16.
- J1850 PWM --The connecter should have metallic contacts in pins 2, 4, 5, 10, and 16.
- Terminate --The connector should birth metallic contacts in pins 4, 5, 6, 14 and 16.
If your vehicle has this style connector, but doesn't wealthy person these pins populated, you probably possess a pre-OBDII vehicle. To add some confusion, tied having the connector with the contacts shown above is not a vouch of OBD II compliance. This style connector has been seen on much pre-1996 vehicles which were not OBD II compliant.
Information happening Pre-96 Cars
A reader with the California Air Resouces Board provided this lean of pre-96 OBD II engine designations. Mark that CARB recognizes engine series, preferably than vehicle models, and then the engine designations are trueness key, with the fomite models provided as a good manners.

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