A Volvo truck climate control module reset may be necessary to fix certain issues with your vehicle.
If you come across a dead or unresponsive climate control module, then you may want to perform a reset.
However, if you have never done this before, you may want to check out this post to find out how it is done. Consider the tips we’ve shared with you below to ensure the best results you want from doing a climate control module reset.
Let’s get started.
How To Do A Volvo Truck Climate Control Module Reset
Before we go ahead with the steps you need to take, it is helpful to understand why you need to do a reset in the first place.
For instance, you may have encountered a non-responsive climate control module right after you have disconnected your battery. After reconnecting and the climate control module still fails to respond, then you may find yourself confused as to why this has happened.
It also occurred to some people where their CCM had died. Yet, after jump-starting the battery while making sure it is a new battery, this helped to revive the CCM.
There are many possible reasons why this issue happens. For instance, it could be due to a faulty climate control power stage. This controls the speed of your blower fan on a variety of settings. So, if it ends up going bad, this defaults to a full blast.
There is also a possibility that your actual climate control unit is the one having problems. The power stage, which is located close to your blower fan right under your dashboard, may be malfunctioning. With this in mind, you may want to check your fuses.
In other cases, the air conditioning control unit is dead. You may either replace it with a brand new AC control, which is more expensive while used ones are cheaper.
There were also other people complaining about the CCM and the battery immediately died. The issue can be attributed to the relays, so it is best to inspect these components. You may want to take out your battery terminals and check the connections well. Then, you may need to reset your computer afterwards.
In some other cases, the climate control panel suddenly becomes unresponsive after replacing the battery. One way to fix this is by resetting the CCM. To do this, you need to check your manual and determine the slot where the fuse for your AC is. Make sure it is not blown, since a blown fuse can also cause this problem.
For instance, there were some people who had a blown fuse, specifically the one that controls their AC unit. Hence, the CCM began to malfunction.
If your climate control has gone out after you have jump start your vehicle, your mechanic may advise you to replace this unit. But in reality, the weak point in your circuit is your temperature sensor. This component is found at the back of the small vent on the front portion of your climate control. You can buy this component and connect the new sensor, which should be a cheaper option to fix the problem.
First, turn your ignition switch to the number 2 position. Then, connect your battery lead. Begin the upper electronic module and then initialize your central locking, sunroof, and the interior lighting. You can initialize these when you unlock the car with either your key fob or car key.
Then, calibrate your blower fan. With the manual or standard climate control, your blower fan needs to be recalibrated. Turn the ignition on, then put your fan switch to the maximum setting and then turn to the minimum setting.
Close the sun roof and then put the ignition switch to position I, push the control to place it in the tilt position, then release the switch. Close your sunroof by operating the control for about 5 seconds and then finally release the switch.
Lastly, there were some people you left without AC. In the hot, summer months, this is not the best situation you want to be in. So, you may want to check if the fuses are okay, or if there are any other problems with the module such as the STC and AC. If it is only the module, then the only thing you need to do is to have it replaced by your mechanic, although it can be a rather expensive fix, nonetheless.
Recalibrating may be helpful when you want to do a Volvo truck climate control module reset. To do this, you need to perform these steps:
- Close the bonnet and doors
- Put the key in the II position while making sure the engine is not running
- Hold the passenger and driver window switches in your driver’s door panel for about 5 to 8 seconds
- Release the buttons and take the ignition key out
- Operate the key fob twice
- Turn your heater controls to high and then turn off.
