6 Causes of Volvo Power System Service Urgent

If you are getting the “Power System Service Urgent,” it is your vehicle’s way of telling you that the power system of your Volvo is below the recommended threshold.

Typically, the fault is from your alternator or battery, and you would need to replace or repair the damaged parts.

This article will examine some causes of the  “Power System Service Urgent” warning message on your Volvo. We will also discuss some possible fixes to rest the warning message.

Why are you seeing the Power System Service Urgent Message?

There are a couple of reasons you may be getting the warning message. The primary reason is a bad alternator system. Other causes include damaged batteries, wiring issues, bad regulators, loose serpentine belts, corroded battery terminals, etc. Furthermore, any components of the power source system may trigger the warning. 

1. Faulty Alternator 

A faulty alternator has been identified as a primary cause of this warning message. The alternator helps generate electric power for the car’s electric system and battery. Where the alternator is bad, it cannot properly charge the battery. The Control module may interpret this as low voltage and trigger the warning message.

2. Bad regulator

The regulator is within the alternator and may contribute to the power system issue. It regulates the alternator’s voltage output, ensuring the charge is stable and consistent. However, when the regulator is faulty, the voltage becomes unpredictable, damaging the electrical system and triggering the error message. It could also cause the battery to overcharge or undercharge.

3. Corroded Battery Terminal

A corroded battery terminal can trigger the warning message in your Volvo. Corrosion causes a poor electrical connection with the battery. It also causes low battery volt supply to the engine system, leading the ECU to think the battery is bad, triggering the error. We recommend cleaning the terminals with a brush.

4. Electrical issue/ blown fuse:

It is possible that a short electrical wiring or blown fuse may trigger the “Power System Service Urgent” warning message in your Volvo. Overheating of wiring may cause the wire to short/ break causing electrical complications.

5. Power System Overheating

Overheating components within the power system, including the battery, alternator, or wiring, can completely degrade the power system’s performance and cause potential failure.

6. Faulty PCM

The PCM stands for Powertrain Control Module. It controls and manages several functions, including the power system. Faulty PCM or malfunction results in abnormal behavior that triggers the warning message.
