I have a 83 supra, can see where to read odbc codes from later models but I don't see a diagnostic center located under the hood how to I read the codes?

ODBC-2 code reader is used to read the codes and reset the codes once read. This web site will help you troubleshoot the codes http://www.obd-codes.com/trouble_codes . The reader can be purchased for usually less than paying a auto mechanic to read the codes and perform the reset. The plug to read the codes is usually under the driver side dash. If you lay down on the ground you will see it. ODBC-2 reader are sold at every auto parts store and are easy to use.

the ecc diagnostic plug is what ford used b 4 going to the obd 2 system check with ur local ford dealer for checking codes

Some models are under the steering wheel knee pad. Other are under the hood, near the fuse panel.

Hi there,

On earlier models, the ECM (also known as PCM & ECU) was located above the passenger side 'kick panel', hidden behind the glovebox.

However, on later models, Mitsubishi mounted the computer in behind the Centre Console (below and behind the ashtray area). You'll need to remove both centre console side panels.

The one you want, has a part number starting with: MR *****





Note: NEVER replace the PCM, unless your diagnostic codes codes confirm the PCM is faulty. Have your diagnostic codes read before disconnecting.


Cheers,

Don't try to start the car with a gas leaking, pop the hood and locate the leak, you need to get the codes from the computer, be carefull, you don't want to burn your car to the ground.

The PCV valve is located under the hood, center, upper engine area, top of engine, mounted in passenger side of intake manifold. I hope this helps and good luck.

Check the fuses for the parking lights and the backup lights:

On earlier models, the fuse panel is located on the firewall above the driver's left foot. On later models, the fuse panel is located on the underside of the instrument panel, covered with an access door.

Older cars used the OBD 1 system for retrieving codes, check your owners man, for the location of the diagnostic connector under the hood, use a compatible scanner, most newer scanner's have the cable needed for making the connection. Good luck!

To set the timing, you will need to connect a jumper wire between terminals E1 and TE1 on the diagnostic terminal. This diagnostic terminal is located just aft of the engine compartment fuse box. It is a black plastic box marked "diagnostic" on the cover, which flips open to reveal the terminals inside. There is a diagram on the inside of the cover which explains the terminal positions. On the Turbo model, you need to remove the forward section of the engine cover to gain access to the number one spark plug wire.

Diagnostic Connector To read Diagnostic Trouble Codes (DTC's), the test connector for the electronic engine control system must be used. The test connector is more commonly referred to as the Data Link Connector (DLC). On all Jeep models through 1990, the DLC is a 6-pin and a 15-pin connector located under the hood on the right side of the engine compartment. On 1991–93 models, the DLC is located under the hood on the left side of the engine compartment near the powertrain control module. On 1994–98 vehicles, the DLC is located in the passenger compartment, under the driver side dashboard.
