This message is your car’s way of telling you that its connected services—the ones that handle emergency calls, remote start, and vehicle location—need a bit of attention.

Key Takeaways

• Reset the system: A soft reset can often resolve temporary software glitches.
• Check your subscription: Ensure your Volvo On Call service is active and paid.
• Update vehicle software: Install the latest updates via the infotainment system.
• Inspect the telematics unit: Physical damage or loose connections may require service.
• Contact Volvo support: Use the app or call for professional assistance.
• Re-sync the mobile app: Log out and back in to refresh the connection.
• Replace the TCU battery: A depleted battery in the telematics unit causes errors.

What Does “Volvo On Call Service Required” Actually Mean?

Before you start worrying, let’s demystify the message. Volvo On Call (VOC) is a telematics system. Think of it as your car’s personal cellular connection and GPS unit, all in one. It’s what powers your ability to lock/unlock doors from your phone, send destinations to the navigation, or get emergency help if airbags deploy.

The “Service Required” warning specifically relates to this system, not your engine, brakes, or transmission. It means the car’s computer has detected a fault in the communication module, its software, or its connection to the cellular network.

The Heart of the System: The Telematics Module

Inside your Volvo, usually under the dashboard or in the center console, is the Telematics Communication Module (TCM). This little box is the brain of VOC. When it can’t communicate properly, your dashboard lights up. Common triggers include a software glitch, a weak or lost cellular signal for an extended period, or a drained backup battery inside the module itself.

It’s Usually Not an Emergency, But Don’t Ignore It

Here’s the key takeaway: your car will still drive perfectly fine. This is a comfort and convenience system alert. However, if the system is faulty, features like automatic crash notification or the SOS button won’t work. That’s why it’s important to resolve it, but you typically don’t need to pull over immediately in a panic.

Step-by-Step: How to Reset the Message Yourself

Often, the “Volvo On Call Service Required” message can be cleared with a simple reset. It’s like rebooting a frozen computer. Always try these steps first—they fix the issue a surprising amount of the time.

The Classic Infotainment Reboot

This is your first and easiest line of defense. The Sensus infotainment system is closely linked to the VOC module.

• Turn on your car (or put it in ignition mode).
• Press and hold the home button at the bottom center of your screen. This is the button that usually looks like a little house.
• Keep holding for about 20-30 seconds, until the screen goes completely black and you see the Volvo logo reappear.
• Wait for the system to fully reboot. This can take a minute or two. Once it’s back, drive the car for a few minutes and see if the warning clears.

The Deep Sleep Reset (For Stubborn Cases)

If the soft reboot didn’t work, a more thorough reset can help. This involves disconnecting the car’s main 12V battery to clear all temporary electrical memory. Caution: This will reset other memory settings like clock and radio presets.

• Ensure the car is off, keys are away, and all doors are closed.
• Open the trunk and locate the 12V battery.
• Using the correct size wrench, disconnect the negative (black) terminal first. Secure the cable so it doesn’t touch the terminal.
• Wait for at least 15 minutes. This gives all systems time to fully power down.
• Reconnect the negative terminal tightly.
• Close the trunk, start the car, and let it idle for 5-10 minutes. The system will re-initialize. Check if the warning is gone.

Check Your Volvo On Call Subscription Status

Sometimes, the problem isn’t inside your car—it’s on the billing end. Volvo On Call isn’t a free service forever. After an initial trial period (usually 3-4 years on newer models), it requires a paid subscription.

How to Verify Your Account Status

• Open the Volvo On Call App: On your smartphone, check the app’s status. Is it showing an active subscription? There may be a notification about an expired plan.
• Check Your Email: Volvo sends renewal reminders. Search your inbox for emails from Volvo Cars or Volvo On Call.
• Call Volvo Customer Support: They can quickly tell you if your Vehicle Identification Number (VIN) is linked to an active subscription. Just have your VIN ready (found on your windshield or registration).

Renewing a Lapsed Subscription

If your subscription lapsed, renewing it is straightforward through the app, the Volvo Cars website, or with a support agent. Once renewed, it may take up to 24 hours for the system to sync and the warning message to disappear. A quick infotainment reboot after renewal can help speed this up.

When to Seek Professional Help: Common Faults and Fixes

If you’ve tried the resets and confirmed your subscription is active, the issue might be hardware-related. Here are the typical culprits a Volvo technician would check.

The Telematics Module Backup Battery

Inside the VOC module is a small, rechargeable backup battery. Its job is to maintain the system’s memory and allow it to make emergency calls if the car’s main battery is damaged in a crash. Over 4-5 years, this battery can fail. A diagnostic scan will often reveal a fault code pointing directly to this backup battery. Replacing the entire TCM unit (which includes the battery) is the usual fix.

Faulty Antenna or Wiring

The module needs a clear signal. A damaged shark-fin antenna on the roof or a corroded wiring connection can cause intermittent or total communication loss. A technician can test the antenna signal strength and check the wiring harness for issues.

Software Update Required

Like your phone, the TCM needs occasional software updates. Sometimes, a bug in an older version can cause persistent errors. A dealership can perform a software “reflash” or update to the latest version, which often resolves gremlins in the system.

Preventing the “Service Required” Message in the Future

A little proactive care can help keep your Volvo On Call system healthy and that warning light off your dash.

Keep Your Software Updated

When your car notifies you of an available software update (often sent Over-The-Air or available at a dealer), don’t delay. These updates include stability fixes for systems like VOC.

Maintain a Strong Battery

A weak or aging main car battery can cause all sorts of electrical gremlins, including intermittent VOC errors. Have your 12V battery tested regularly, especially as your car ages past 3-4 years.

Drive Regularly and in Good Coverage Areas

The TCM’s backup battery charges from the main car battery. Frequent short trips can keep it from getting a full charge. Additionally, while occasional signal loss is normal, chronic parking in deep underground garages can stress the system. A good highway drive now and then helps keep everything topped up and communicating.

Taking Back Control of Your Volvo’s Connectivity

Seeing “Volvo On Call Service Required” can be a momentary headache, but it’s almost always a solvable one. You’re now equipped with the knowledge to tackle it methodically. Start simple with a reset. Check the practical things like your subscription. Understand that if those don’t work, it’s likely a known hardware item like a backup battery—a fixed cost with a clear solution.

The goal is to get you back to enjoying your Volvo’s fantastic features without that nagging light on the dash. With this guide, you can approach the problem not with dread, but with the confidence of knowing exactly what to do next. Here’s to many more miles of safe, connected, and warning-free driving.
