6932Photo may not be specific to your vehicle

Follow the OBD Scanner's instructions to retrieve diagnostic trouble code(s).

Troubleshoot all possible symptoms that relate to the diagnostic trouble code(s).
Ex: P0300 รข€“ Random/Multiple Cylinder Misfire Detected
This code indicates that the vehicle's onboard computer has detected that not all of the engine's cylinders are firing properly.
The last 2 digits of the code represent the detected cylinder. In this case 00 is a random cylinder misfire code. A P0301 would be a misfire detected on cylinder 1. It will be much easier to diagnose if a specific cylinder is detected.There are numerous components that could set a misfire code. Below is a list of possible components that could be at fault:
Faulty Spark Plug Wire(s) and/or Plug(s)
Faulty Coil Pack(s)
Faulty Fuel Injector(s)
Faulty Oxygen Sensor(s)
Faulty Catalytic Converter(s)
Once you have diagnosed the problem that set the check engine light on, you must now replace the faulty component(s).Once the new component(s) has been replaced, use the OBD Scanner to erase the diagnostic trouble code(s).Start your vehicle and monitor the status of the check engine light.If further diagnosing is required, these steps must be repeated until the check engine light is no longer on.

Car stereo wring procedure?

Overview of Car Stereo Systems

  • A car stereo system consists of 4 main components and the wiring that connects them. These are the head unit, the main speakers, optional amplifiers and the sub-woofers, which are also optional but generally considered a necessary part of any good system.
  • Know that the core of any car stereo is the head unit, which is the cassette or CD player that goes in the dash. All the other components are connected to the head unit by at least one pair of wires.

  • Know about car speakers. The main speakers are usually 2 in the front and 2 in the back, although with what are known as component speakers, each speaker is broken down into two speakers: one for the highs and one for the bass. Each speaker or speaker set (known as a channel) connects to the head unit via a pair of wires. Generally if you are installing a new head unit you want to install new speakers.

  • Know about amplifiers. Amplifiers provide extra power to your speakers and/or extra channels of power for additional speakers. The most common use for an amplifier (amp) is to power subwoofers. The amp connects to your head unit via an RCA cable and often a "remote on" wire, and also connects directly to your car battery through a fused "hot" wire and to the car's chassis with a short ground wire. This article assumes the use of a single amplifier connected to a pair of subwoofers. If you do not have these components simply ignore the steps specific to the amp, doing so will not affect the rest of your installation.

  • Know about subwoofers. Subwoofers are part of any good stereo system. They provide the deep bass that small speakers cannot achieve. Subwoofers are connected to the amplifier which can usually be mounted right to the subwoofer box. If you do not have subwoofers you can simply ignore the steps specific to them.

Preparing for the Installation

  • Be properly prepared. This is extremely important since you do not want to realize you're missing something in the middle of the installation.

  • Purchase the following: A car stereo wire harness which connects the existing wiring for your old head unit to your new one (this will be specific to BOTH the model and year of your car AND to the make of your new head unit); an amplifier wiring kit which will contain all the wires to get power and signal to your amplifier; six feet of 14-gauge speaker wire for the subwoofers. Your speakers should have come with their own speaker wires.

  • Obtain a guide to removing the dash, doors panels (or whatever compartment the speakers are in), and floor molding of your car. You may be able to find a guide for this online. If not, you can get a repair manual for your car at most automotive stores and online).

  • Gather the following tools: Screwdrivers to fit the job, pliers, wire cutters, wire strippers, a utility knife, sand paper or a file, electrical tape, a 9-volt battery, and any other tools that the instructions for installing the head unit and your car guides specify.

The Installation

  • Disconnect the ground (negative) cable from your battery first and foremost. NEVER work on the electrical system of your car with this connected.

  • Install your new speakers. Start by removing the paneling of the speaker enclosure. Unscrew and disconnect the old speaker.

    Ideally the speaker wire will be connected to the old speakers with a metal clip that can then slide right on to your new ones. If not, cut the wire off the old speakers, strip about half an inch of it, then cut the last 6 inches or so off the speaker wire that came with your speakers so you have the proper connectors with a little wire attached, strip a half inch of those wires and twist connect them to the existing speaker wire. Bend the twists so they are in-line with the wire and wrap each connection in electrical tape so no wire is showing to protect them.

    Attach the connectors to your new speaker. Make sure to connect the negative wire (-/black) to the negative terminal on the speaker and the positive wire (+/red or white) to the positive one. Screw the speaker in place. If you have component speakers, and therefore a crossover, make sure the crossover is secured in the speaker compartment so that it does not bounce around while you drive.

    Wait to put the speaker enclosures back together until you have installed the head unit.

  • Follow the instructions you got for removing whatever part of the dash covers it and take out your existing head unit. Connect the car stereo wire harness to the connector that was attached to your old radio and attach the other end to your new one. Connect the antenna cable (the single wire with the big plug at the end) to your new head unit as well.

    If the speaker wires are separate from the harness connect them using the method of stripping, twisting, and taping described above. Do this one at a time or use masking tape to label the wire to avoid confusion. If you are having trouble figuring out which wires go to which speaker or which is positive and negative read the tip at the bottom of this section.

    Do not put your new head unit into the dash yet-you still need to connect the amplifier to it. Put the speaker enclosures back together now.

  • Attach the thick positive (+/red) power cable for your amplifier to the connector on positive terminal of your battery. The kit you purchased should have come with an o-ring on one end of the wire (you may have to crimp it on yourself, if so do it on the end with the fuse), this ring can be sandwiched in the bolt on the connector that connects your car to the battery.

  • Put the fuse in the fuse holder.

  • Run the power cable through the firewall of your car (there is usually an opening on the drivers side) and along to the back of the car where your amp is. It is usually best to run this wire under the plastic molding that goes along the bottom edge of your car, you never want the power cable to come near any speaker wires. At the same time run the remote on wire (a really thin wire from the amplifier wiring kit), through the dash where the head unit will sit, along with the power cable to the amp.

  • On the other side of the car run the RCA signal cable through the dash from the head unit to the amp (it's a pair of wires together with connectors on each end).

  • In the back of the car pick exactly where your amp and subwoofers are going to go. Part of choosing this is that the thick black ground cable (negative) needs to have a place to connect to the metal frame of your car. This should be as short as possible, you never want the ground cable to be longer than 3 feet.

  • Find a good screw or bolt, take if off and sandpaper the metal surface that the o-ring will make contact with, then screw it down tightly.

  • Attach the RCA signal cable and the remote on cable to your head unit and attach the power, ground, RCA signal, and remote on wires to your amp.

  • If you have not already done so, place your subwoofer box in the trunk and attach your amplifier to it if that is what you are doing. If you are not going to screw your amp to the subwoofer box then it must be secured to something else.

  • Attach the 14-gauge speaker wires to the left and right channels of the amplifier and to the speaker connectors of the subwoofer box.

  • Mount your head unit into the dash. Double check all of the connections on the back of it to make sure they are secure. Then slide your head unit into its slot in the dash and screw it securely in place. Before you re-attach the dash, reconnect the ground (negative) cable to your car battery and turn the stereo on and move around the car listening to each speaker to make sure everything is working properly. Then put the dash back on.--------------------------------

    Install a Car Stereo Speaker Wire Through a Front Door:--------------

  • Remove the door panel from your car's door. The exact method depends upon your specific vehicle, but as a general rule first remove any visible screws from the panel, then pry around the edge of the door panel with a panel tool to release any retaining clips. Lift the panel upwards and away from the door and disconnect any wiring for power door locks or window controls.Remove the kick panel from the car. This is the plastic panel in front of the door and below the dash. As with the door, remove any visible screws and then pry off the panel.Find the entrance to the rubber boot that vehicle wiring runs through to reach the door. This will be at the back edge of the kick panel.Tape the end of your speaker wire to a stiff wire. A straightened coat hanger works well for the purpose.Push the end of the wire through the rubber boot until you can see it emerge into the door cavity. The space may be tight, so be patient and try to angle the wire if you hit any obstructions or tight spots along the way.Un-tape the speaker wire from the stiff wire and pull as much wire into the door as you require for hookup.
