What does the voltage unstable mean in response to the 14-volt power module system? How does the P0A8C error code gets stored in the vehicle? Is it possible to get rid of this error code? Do these questions arise in your mind? Keep reading. ECM, abbreviated as engine control module looks after the 14-volt power module. The error code P0A8C is set in the vehicle by the engine control module if it does not obey as per the factory conditions.

The 14-volt power module system voltage unstable generally refers to the low voltage system which does not function correctly and results in the error code getting stored in the vehicle. Monitoring the current to the voltage system that is low is correctly done by the accessory DC power module which is commonly known as the 14-volt power module. Excessive voltage fluctuation will result in the P0A8C error code getting stored in the vehicle by the 14-volt power module which finally disables the low voltage system.

What causes this problem with the 14 Volt Power Module System Voltage Unstable?

• 14-volt power module might be defective.
• There might be an opening in the 14-volt power module or shorted circuit.
• 14-volt power module circuit has an electrical connection which might be very weak.
• 14-volt power module software has to be updated.

1. 14 Volt Power Module - Carefully check the 14-volt power module if it is defective or broken. If you find it damaged, get the replacement for your 14-volt power module from Parts Avatar at best prices online
2. 14 Volt Power Module Harness - The 14-volt power module harness must be carefully checked for any possible damages or defects. If it is broken or detached, replace it immediately.
3. 14 Volt Power Module Software - Check the software of the of the 14-volt power module if they are properly updated. Update them as soon as possible.
4. Engine Control Module (ECM) - P0A8C error code can get stored in the vehicle if the engine control module is faulty or defective. Change the faulty engine control module as soon as possible.
5. Car Battery - A faulty, damaged or bulged car battery will make the P0A8C error code to get stored in your vehicle. Get rid of this error code by replacing the damaged battery.

Interested in knowing the symptoms to OBD code P0A8C? If yes, then you have arrived at the right place. We at Parts Avatar have listed out few common symptoms associated with 14-Volt Power Module System Voltage.

Common Symptoms

Now all your problems would vanish within no time.

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• Diagnosing the P0A8C trouble code is not very difficult.
• The mechanic will use a scanner to find the error code in the vehicle. After checking this, a scanner will be attached to the diagnostic port of the vehicle so that every stored codes and freeze frame data can be recovered.
• This can help with the further diagnostic process.
• If there are any advanced process, the advanced scan tool which is named as Auto hex will be used by the mechanic for an advanced process.
• Firstly, the mechanic will check the 14-volt power module and as well as its harness, sometimes, the joints may be detached or separated or the component itself can be defective. In such cases, the damaged component will be repaired.
• A faulty engine control module can be a very rare case which can give rise to this error code. If it is found to be damaged, the mechanic will replace it with a new component.
• Once every repair works is done and the damaged components are replaced, the mechanic will reset the code and see if the error code still appears by test driving the vehicle.
• This step will eventually help the mechanic to know as to where the error actually occurred.

Common Mistakes When Diagnosing the P0A8C Code

• Engine control module might be defective (ECM).
• Battery issues.
• Forgetting to update the software.
