AFM Disabler Problems And Solution

Getting the best AFM disabler is the best way to avoid issues. Nevertheless, let’s look at what problems an AFM can cause to your truck, as well as their corresponding solutions. Some common side effects of Range AFM include:

1. Unresponsiveness

Range Technology AFM disablers can switch from a 4 cylinder mode to an 8 cylinder mode for higher peak performance at the cost of more fuel. However, this switching can be unresponsive at times which can cause trouble with your driving. There can be several reasons, including compatibility issues, a faulty disabler, or outdated firmware. It is important to check if the disabler and switch are working before setting off. Not being able to disable the AFM properly can cause issues as well.

Next, you should check to see if the firmware is updated or not. You need to consult the manufacturer about the firmware, and they can perform the necessary update.

2. Lifter Failure

One issue you can often encounter with lifter failure. Frequently using the AFM disabler device can cause the lifter to experience degradation and might end up breaking down from stress later. This can be a serious issue and can greatly damage your truck. 

Solution

Learning how to prevent afm lifter failure is important. You must perform proper maintenance on the AFM lifters on your truck. Make sure to oil them and look out for any signs of deterioration. If needed, you should change parts out or perform servicing to ensure the parts are in top condition. Proper maintenance is the best course of action to prevent this issue.

Make sure to inspect the lifters before leaving for any ride on your vehicle. If your lifters are in good condition, the transition should be smooth and not produce any noise. If you’re experiencing noises or rough switches, you might need to stop and take a look at your AFM lifters. You can also report these signs to the workshop employee for an effective solution.

3. High Exhaust Noise

Range Technology AFM disabler modules can result in your GM truck emitting loud noises once the AFM is disabled. Alongside causing noise pollution, they can strain your exhaust and cause it to deteriorate over time. This deterioration can also extend to your vehicle’s engine with time. If left unchecked, it can spiral into a big issue for your vehicle.
