Fix It

You can reset the computer codes on your Honda right from your home garage, saving time and money. The trouble codes are sent to the On-Board Diagnostics computer (OBD) from sensors positioned throughout the car. These codes pinpoint the service needs of the vehicle. Read the codes using a handheld computerized device called an OBD scan tool. Once the codes have been read and the repairs done, clear the codes using the OBD tool. This will reset the computer and shut off the lights.

Instructions

1

Find a port on the underside of the drivers side dash that is the same size and shape as the connective end of the OBD scan tool. Plug the scan tool into this port.

2

Put the key into the Hondas ignition and turn it to the "On" position, taking care not to crank the engine. This will power on the scan tool.

3

Wait while the scan tool reads the codes. Find a command on the scan tool that says "Clear Codes" or something similar. When the main menu reappears, the codes have been cleared.

4

Unplug the scan tool and start the engine. Verify that all warning and service lights have shut off.

Honda introduced the mid-sized complement to its compact Civic -- the Honda Accord in the 1976 model year. The Accord began its life as a feature-packed vehicle for its era sporting high-end elements, such as an AM-FM stereo, rear defroster and a remote hatch release. The 2001 Accord EX came standard with a wide array of features including an AM-FM stereo with a 6-disc CD player. An anti-theft system protected the stereo by locking the stereo from working when it lost power until you entered a five-digit code. If youve lost the code, contact the dealership with the radios serial number to get the code.

Instructions

Entering the Radio Code

1

Insert the key in the Accords ignition and turn it to the "Acc" or "On" position.

2

Turn the radio on by pressing the volume button, if needed.

3

Observe as "Code" appears on the radios display.

4

Enter the five-digit code from the radio code card the dealership provided with the vehicle, by pressing the corresponding preset buttons on the radio. If entered correctly, the radio begins to play. If the radio does not play, turn the Accord off and retry from Step 3. If you do not have the five digit code, see the section titled "Obtaining a Lost Radio Code."

5

Turn the Accord off.

Obtaining a Lost Radio Code

6

Turn the Accords ignition to the "Acc" or "On" position.

7

Press and hold the number 1 and 6 preset buttons and turn on the radio by pressing the volume button on the radio.

8

Observe as four digits appear on the radios screen, make note of these numbers. After five seconds, a second set of four numbers appears on the screen, write down these numbers. All eight numbers make up the radios eight-digit serial number.

9

Take the eight-digit serial number to a Honda dealership to obtain the radio code.

The Mercedes-Benz C class was once known for its reliability, but since the merger with Chrysler in the 90s, Mercedes as a whole has lost much of its engineering reputation. To that end, many of the 2001 C-class cars have endemic electrical and mechanical faults; the SRS fault being one of the leading issues. SRS stands for the supplemental restraint system and is supposed to pre-tighten the seat belts in the event of a crash, but in practice serves only to require periodic trips to the dealership to fix its faulty sensors.There is, however, a way around this.

Instructions

1

Buy a Mercedes-Benz code reader from a website, there are many available. Make sure the code reader has a 16-pin OBDII standard socket port. The 16-pin port is what the diagnostic port on the C320 uses. 32-pin readers can be used, but an adapter and rather complex software is needed. It is simpler and cheaper to just get a 16-pin reader. No batteries are needed, as the code reader draws power from the car itself.

2

Start the car and wait for the reader to flash the name of the code reader, then press the "Read" button. It will be the green button to the bottom left. It will flash the error code three times; after the third time, press the erase button. Depending upon the model of code reader, you may have to press "Erase" after every code or only once for all the codes.

3

Disconnect the code reader and turn off the car. Then turn the car back on and replug the reader to check to see if the erasure took. If it has, you are done; if it has not, you will need to replace the SRS sensors themselves, which only a Mercedes-Benz mechanic can do.

After you have retrieved the transmission code on your 95 Dodge Intrepid and had the transmission repaired, the code should reset itself. However, this is not always the case. You might see a warning light on the instrument panel even after the vehicle has been repaired. To reset the transmission code and shut off the light, either disconnect the battery or clear the code using an OBD I scan tool. It is better to use the scan tool because disconnecting the battery will erase all of the computers codes and you will have to reset the radio, clock, alarm and other components.

Instructions

1

Plug the OBD I scan tool into the port under the drivers side dashboard near the steering column. Dont force it in. Just turn it until it fits so you dont damage the pins.

2

Put the key into the ignition and turn it to the "On" position, but dont crank the engine. Wait while the scan tool retrieves the codes.

3

Find and select the "Delete Codes" option. This will clear the transmission codes as well as other trouble codes. The computer is now reset. Unplug the scan tool from the port.

4

Start the engine and verify that all warning lights have shut off of the instrument panel.

Vehicles are equipped with key codes, which are number sequences that link a key to its specific vehicle. If you need a new key for your vehicle, youll need to have the key code to create your key; without it, you wont be able to start your car. Key codes are noted in the paperwork given to you when you purchased your car. If you cannot find the key code in your paperwork, dont panic because your vehicle identification number contains your key code as well.

Instructions

1

Contact your local car dealership or a professional locksmith to request a new key for your vehicle. Both will need to make sure they have the correct type of blank key for the make and model of your vehicle.

2

Provide the dealership or locksmith with your key code. If you cant find your key code, you can provide them with your vehicle identification number (VIN). Your VIN is located on your vehicles paperwork, your car insurance paperwork, and your title and registration paperwork. It is also located on the drivers door panel and inside the windshield on the bottom left corner, visible from outside your car.

3

Schedule a time to go to your dealership and get your new key, or for your locksmith to come to you with your new keys. You will be asked to provide some form of proof that you are the owner of the vehicle, such as your registration or insurance card. Pay for the service provided to you and for your new keys.

You can reset the code on your 92 Cadillac from your home garage, saving yourself time and money. The computer in your Cadillac generates and stores trouble codes that pertain to the vehicles various systems. You first have to run a diagnostic test using an OBD scanner to pinpoint the problem. After the problem has been discovered and repaired, you must reset the code using the same OBD scanner. Always fix the problem first before attempting to erase the codes or you risk further damage to your vehicle.
