Pop the hood to your Honda CR-V.

2

Locate the battery under the hood. This is to the right of the engine.

3

Determine which of the leads is the negative lead. The negative lead will have a "-" sign next to it.

4

Loosen the terminal with a socket wrench.

5

Pull the negative lead off of the battery to disable the car alarm.

The tire pressure monitoring system on a 2005 General Motors truck consists of four tire sensors, a radio frequency receiver, and a number of modules that work together including the BCM, PCM, and passenger door module, or PDM. The tire monitoring system is activated by default, but whenever the PDM is replaced the Tech 2 scan tool must be used to enable the tire pressure monitoring system. The Tech 2 is GMs factory scan tool, and it is also the only scan tool that can re-activate the TPM system.

Instructions

1

Turn the ignition ON and connect the Tech 2 to the vehicles diagnostic communications port.

2

Power on the Tech 2 and select Diagnostics from the main menu. Select 2005 for the model year.

3

Select LD Trk, MPV, Incomplete. Choose the make of your truck from the menu, then select the body type.

4

Select F2: Chassis, then select Equal to or Under 8600 GVW.

5

Choose Tire Pressure Monitor, then choose TPM Option Enable. Select the option to enable the TPM system from the TPM Option Enable screen. Press exit to move back to the TPM main menu.

6

Select the Tire Type/Pressure Selection menu and enter your tire and pressure information. This information is located on the door sticker inside the drivers door. Press exit to move back to the main menu once youve entered this information.

7

Select Learn Sensor Location from the TPM main menu. Follow the on-screen instructions to allow the PDM to learn the sensor locations. Press exit to move back to the main menu once you are finished. Power off the Tech 2 and disconnect it from the vehicle. Turn on the engine and confirm that the TPM system is activated and operates properly.

Motor vehicle exhaust systems are all either welded or clamped into place. Each has its benefits and drawbacks; some parts will require one or the other.

Types of Exhaust

Auto exhaust systems typically come from the factory welded together. It is with the replacement of pipes, mufflers and catalytic converters that you will see clamps put into use, though some new cars will come with a combination of clamps and welding. The customization of exhaust systems will also result in frequent clamp use, as will older model vehicles mainly because they have had parts changed.

Benefits of Each

The benefits of welding are the complete seal and prevention of leakage that it provides. This reduces pollution and improves engine compression and possible rattle. Clamped exhaust systems make it far easier to replace parts when necessary and remove the cutting and welding elements from the equation.

Considerations

The drawback to welded exhaust systems, especially when it comes to replacement parts, is the potential for cracking should the weld not be done perfectly. The main drawbacks to clamping are the imperfect seals that are formed, the potential for loosening and the loss of compression and pollution into the air.

Combination Systems

Exhaust elements near to the engine including catalytic converter often require welding because of the high pressure exhaust they withstand due to their placement. Clamps tend to be used at the back end of the car.

Many parts rely on the electrical system of a vehicle to power them so that they function properly. Several tools can assist when trying to find and fix auto electrical problems. A voltmeter, an ohmmeter or a simple test light can make the job of locating electrical issues within a vehicle a lot easier and safer.

Fuse Help

Although replacing a blown fuse can sometimes be enough to fix auto electrical system problems, the real issue is often what caused the fuse to blow. Either way, replacement fuses should never exceed the capacity of the blown fuse being replaced as the circuit will not be able to handle this.

Relay Help

A relay is a switch that brings voltage to a circuit while also lowering the amount of wiring needed within the circuit. Jumper wire can be used to bypass a circuit breaker to test a circuit. This same method can be used for a relay as well; if the circuit works after bypassing the relay, then the problem indeed lies within the relay.

Circuit Help

When a circuit is dead, the load point is the first place to look; checking the voltage here with a voltmeter can help to identify the problem. Ground connections could be no good if you find that there is voltage in the circuit. If you find the "hot" wire void of voltage, then the problem is likely due to faulty wiring.

The Combustion Engine

A natural byproduct of a combustion engine is water. It is expelled with the exhaust gases. Fuel is mixed with air and then forced into the cylinders. Once the mix is inside the cylinder, a small explosion occurs before the exhaust camshaft opens and the exhaust is released into the manifold. Because of the intense heat of the combustion engine, the water is vaporized.

The Catalytic Converter

All vehicles since 1980 have catalytic converters. The catalysts convert the unspent fuel into spent fuel before being expelled past the component downstream. Older converters were called two-way converters because they turned carbon monoxide into carbon dioxide and hydrocarbons into water vapor. Not only is water vapor present in the exhaust system coming directly from the engine, but the converter also produces more by chemically altering the hydrocarbons. Nowadays, vehicles employ a three-way catalyst which also reduces harmful nitrogen oxides.

Preventative Maintenance

Depending on your geographical region and driving habits, its not unlikely for the exhaust system to rust and corrode from the inside out. If you live in a place that has severe winter weather and uses sand and salt on the winter roadways, your exhaust may deteriorate on the outside as well as the inside.

Short commutes are a major cause of internal water corrosion of the exhaust system. The water vapors do not have the chance to expel from the system and turn back into water once the vehicle is shut off. When there is no back pressure forcing the water vapors out of the system, the vapors coat the interior of the exhaust components and then form puddles on the bottom. Many mufflers employ a manufactured seep hole in order to allow the water to drain from the muffler. But the pipes and converter do not drain.

If you take short trips, try to run your vehicle for at least 15 minutes to allow the water vapors to purge from the exhaust system.

Car owners in regions with severe weather should wash the undercarriage of their vehicles once a week during these seasons to clean off the sand and salt. Even stainless steel exhaust systems will be compromised in these areas, although they will last significantly longer than aluminized steel systems.

There may be occasions when you will need to disable your Clifford alarm system. It is necessary to know the steps to do so, in order to prevent any inconvenience when its time to disable it. The Clifford alarm system is a popular security system for vehicles with features such as automatic engine disable, code hopping, passive arming and starter kill. Disabling a Clifford alarm system is a simple process that can be done in a matter of minutes.

Instructions

1

Determine the location of the valet button in your vehicle. The valet button is installed in a discreet location in a vehicle. When the Clifford alarm system is installed, the installer generally provides the location and the number of times the button should be pressed.

2

Put the key into the ignition and turn it to the "ON" position, then quickly turn it back to the "OFF" position.

3

Press the valet button -- a small black button -- based on the number of presses for your vehicle. The number of presses is normally between one to five times. This should be done quickly after turning off the ignition. Press the valet button 15 seconds between each press to disable the alarm system.

Rust is a problem no matter where you find it. But when its the bolts and nuts on your exhaust system, it can be a little bit trying. There are multiple ways to remove a rusted bolt from the exhaust, and it will take time and patience to do it correctly.

Instructions

1

Lift up the vehicle using the jack, and support the vehicle on jack stands. Make sure the vehicle is secure on the stands before you crawl underneath it.

2

Apply the penetrating oil on the rusted nut and bolt. You want the oil to soak the area where the bolt and nut connect on the exhaust, because thats whats holding things together.

3

Attempt to loosen the nut from the bolt using the 3/8-inch ratchet and sockets. If it doesnt come off right away, try using the 3/8-inch breaker bar to add extra leverage.

4

Place a fire extinguisher under the vehicle in preparation for the next step. Put on the welding gloves on as well.

5

Heat the bolt on the exhaust system using the Mapp gas torch. The penetrating oil may burn a bit, but it shouldnt cause a fire. Heat the bolt until its red.

6

Try to remove the nut or bolt using the 3/8-inch ratchet and breaker bar. This should free the bolt from the nut, but if not, proceed to the next step.

7

Attach the angle grinder to the air compressor using the air hose, and cut off the nut and bolt. This is a last-ditch effort, but it will remove the hardware from the exhaust. Then you can replace it with new hardware.
