When the low pressure warning is activated you should?

When the low pressure warning is activated you should?

If the low air pressure warning comes on, stop and safely park your vehicle as soon as possible. There might be an air leak in the system. Controlled braking is possible only while enough air remains in the air tanks. The spring brakes will come on when the air pressure drops into the range of 20 to 45 psi.

What must you do when a low pressure warning system activates?

The switch activates either (or a combination of) a buzzer, warning light or a wig-wag (a “flag” that drops into the driver’s view). If the low air warning system activates, you must stop and determine the cause. The warning light must be operational. The buzzer/wig-wag are optional.

What should you do if you get a low air warning?

If your TPMS warning light does come on, find the closest gas or service station and check the pressure of all four tires (plus the spare, if applicable), adding air to any that fall below the range listed on a sticker inside the driver’s door.

At what pressure must the low air warning devices begin to activate?

90 psi
Testing low air-pressure warning devices Begin the test with the pressure above 621 kPa (90 psi ) and the engine stopped or running. With the ignition switch turned on, reduce pressure by repeatedly pressing and releasing the brake pedal. Observe the air-pressure gauges and note when the device activates.

How can you test the low pressure signal?

It is essential that your low pressure warning light functions properly. After allowing the system to charge, you can test the warning signal by rapidly applying and releasing the brake pedal. This will release air from the braking system and the warning signal should come on when pressure drops to a dangerous level.

What can happen if the air pressure gets too low in an air brake system?

Releasing the brakes lets some compressed air go out of the system, so the air pressure in the tanks is reduced. It must be made up by the air compressor. Pressing and releasing the pedal unnecessarily can let air out faster than the compressor can replace it. If the pressure gets too low, the brakes won’t work.

How do you test the low pressure warning system?

What color is the low air pressure warning light?

red
What color is the low air pressure warning light? A low air pressure warning signal is required in vehicles with air brakes. The warning light is usually red and may be accompanied by a buzzer.

What’s the lowest your tire pressure should be?

20 pounds per square inch
If you have standard passenger tires (ninety percent of vehicles do) the lowest tire pressure you can generally drive with is 20 pounds per square inch (PSI). Anything under 20 PSI is considered a flat tire, and puts you at risk for a potentially devastating blowout.

How do you clear low tire pressure warning?

Without starting the car, turn the key to the “On” position. Press the TPMS reset button and hold it until the light blinks three times, then release it. Start the car and let it run for 20 minutes to reset the sensor. You’ll usually find the tire pressure monitor reset button beneath the steering wheel.

What to do when the air pressure warning light comes on?

The Tire Air Pressure Warning Light is On. Now What? If it Comes on While You’re Driving: If you’re driving and the TPMS comes on, pull over to a safe place and stop to check your tires. Unless your tire is completely flat, you’ll want to use a tire gauge to check the tire air pressure in each tire.

What should I do if my TPMS warning light comes back on?

Quick Tip: If the TPMS warning light comes back on after you’ve filled the tire with air, recheck the tire to make sure it is inflated to the proper air pressure. If the tire air pressure is low, you have an air leak and should have the tire fixed or replaced. If that pesky Tire Pressure Monitoring System light won’t turn off, give us a call.
