If you’re working on your car’s air suspension, one of the things you’ll need to do is test the air suspension compressor relay. This is a simple process that only requires a voltmeter or test light.
Here’s what you’ll need to do:
1. Locate the Air Suspension Compressor Relay.
This is usually located near the air suspension compressor itself.
2. Using Your Voltmeter or Test Light, Check for Power at the Terminals on the Relay.
There should be 12 volts present when the ignition is turned on. If there is no power present, then the relay may be faulty and will need to be replaced.
3. Once You’ve Verified That There Is Power at the Terminals, Activate the Air Suspension Switch (Usually Located in the Cabin of the Vehicle).
You should see 12 volts present at one of the terminals on the relay while the switch is activated. If not, then either the switch or relay may be having problems and will need to be tested further or diagnosed by a qualified technician.
Testing the Air Suspension Compressor Relay
Assuming you would like a blog titled “How to Test an Air Suspension Compressor Relay”:
When it comes to diagnosing issues with your air suspension system, one key component you’ll want to check is the compressor relay. Before getting started, make sure that you have a multimeter on hand.
You’ll also need to disconnect the negative battery terminal in order to disable power supply before testing begins.
Locate the air suspension compressor relay and remove it from its socket – and then simply set your multimeter to Ohms and check for continuity between terminals 30 and 87a.
If there is continuity present, unfortunately this means that the relay has failed and will need replaced. However, if there isn’t any continuity detected between these two points, then congratulations -the issue does not lie with your compressor relay!
Troubleshooting Tips
When it comes to troubleshooting tips, there are a few key things that you can keep in mind that will help you get to the bottom of whatever issue you’re experiencing. First and foremost, take a step back and assess the situation.
What exactly is not working?
Isolate the problem as much as possible so that you can better target your efforts.
Once you have a good idea of what’s going on, consult a trusted source for advice – whether that’s an expert friend or family member, an online forum, or even the manufacturer’s website.
From there, it’s all about trial and error until you find a solution that works for you.
When to Replace the Air Suspension Compressor Relay
But what happens when your air compressor starts acting up?
One possibility is that the relay needs to be replaced.The relay is responsible for sending power to the compressor so that it can do its job.
If the relay isn’t working properly, then it won’t be able to send enough power to the compressor and your suspension will start to sag.
In some cases, you might hear strange noises coming from under your hood as well.So how do you know if it’s time to replace the air suspension compressor relay?
The best way is to take your car into a mechanic and have them diagnose the problem. They’ll be able to tell whether or not there’s something wrong with the relay and advise you on what steps need to be taken next.
However, if you’re experienced with cars, then here are a few signs that indicate that it might be time for a new relay:-Your check engine light comes on:
This could mean any number of things, but one possibility is that there’s an issue with electrical components like relays or fuses in your car’s system.-You notice sagging in your car’s ride height:
If this happens gradually over time or all at once after hitting a bump, chances are good that either there’s leakage in one of your shocks or struts OR there isn’t enough pressure being sent to those same parts by the failing compressor relay.-There are strange hissing or grinding noises coming from under your hood:
These sounds usually indicate trouble with the air suspension compressor itself and not necessarily the relay but they are worth mentioning as possible indicators of a larger problem.”.
FAQs in Relation to How to Test Air Suspension Compressor Relay
Is there a fuse for the air suspension?
There is not a fuse specifically for the air suspension. However, there may be a general automotive fuse that powers the air compressor.
This can usually be found in the vehicle’s owner’s manual or by contacting a dealership or qualified mechanic.
If there is no specific fuse for the air suspension, then it likely shares power with another system in the vehicle and does not have its own dedicated circuit.
How do I know if my air suspension compressor is bad?
There are a few ways to tell if your air suspension compressor is bad. One way is to check the pressure in the system.
If it’s low, then the compressor isn’t working properly. Another way is to listen for strange noises coming from the compressor.
If you hear anything out of the ordinary, it’s likely that something is wrong with the compressor. Finally, if your car doesn’t seem to be level when parked, that could also be a sign that the air suspension compressor isn’t functioning correctly.
What is air suspension compressor relay?
An air suspension compressor relay is a device that helps to regulate the air pressure in your car’s suspension system. It does this by turning the compressor on and off as needed, based on input from sensors in the suspension system.
This ensures that there is always enough pressure in the system to keep your car at the desired ride height, regardless of changes in load or road conditions.
How do you test a Air Ride pressure switch?
There are a few ways to test an air ride pressure switch. The most common way is to use a multimeter.
You can also use an ohmmeter, but this method is not as accurate. To test the switch with a multimeter, set the meter to the continuity setting and attach the leads to the two terminals on the switch.
When you press down on the button, you should see continuity between the two terminals. If there is no continuity, then the switch needs to be replaced.
You can also use an ohmmeter to test for resistance between the two terminals when the button is pressed down. There should be very little resistance if the switch is working properly.
If there is high resistance or no connection at all, then the switch needs to be replaced.
Conclusion
Assuming you have a basic understanding of how your air suspension system works, testing the compressor relay is a relatively simple process.
You’ll need a few tools and materials, including a multimeter, but once you have everything set up it’s just a matter of following some clear instructions.
If your compressor relay is not working properly, there are some troubleshooting tips included in this post to help get things back on track. In general, though, if the relay is faulty, it will need to be replaced.
