Seeing the “SRS Airbag Service Urgent” message on your Volvo? This warning indicates a malfunction in the airbag system—possibly in a sensor, clock spring, or module—that could prevent airbag deployment or cause them to deploy unexpectedly. This issue is common in Volvos like the XC90, S60, and V70, and requires immediate attention to ensure your airbag system functions in a crash. You can pinpoint the issue with a full-system OBD-II scanner like YOUCANIC.

What Does the SRS Airbag Service Issue Mean?

The Supplementary Restraint System (SRS) is part of your vehicle’s passive safety features, which means it will deploy without input from the user. This reduces the risk of severe injuries if an accident were to happen. When this fault message appears, it means you have a faulty SRS.

⚠️ Why You Should Fix It ASAP: 

• Safety Risk – This may cause a sudden airbag deployment, leading to an accident while driving. 
• Performance Issues – This may not affect the vehicle’s performance, but this message can be alarming. 
• Costly Repairs if Ignored – Ignoring the issue may result in unexpected airbag deployment, leading to higher repair costs. The estimated cost of repair starts from $200 – $2,500

Common Causes 

• ⚠️ Defective Impact Sensor – The impact sensors are typically located on the side door panels and the front and rear bumper. Check your owner’s manual for the exact location of these sensors since different models have different designs. A defective impact sensor will not send a signal to the airbag module to deploy if a collision happens. Impacts are evaluated by the impact sensors, which send a signal to the airbag to deploy within 20-30 milliseconds of the crash.
• ⚠️ Defective Seat Belt Pretensioner – The seat belt pre-tensioner keeps passengers in their seats, reducing the risk of severe injuries that may happen during a collision. If the pre-tensioner reaches its limit, it will send a signal to the module for the airbag to deploy. The first safety feature keeping you alive during a collision is the seatbelt.
  WHATEVER YOUR SPEED IS, ALWAYS BUCKLE UP YOUR SEAT BELT.
• ⚠️ Broken Clock Spring – A broken clock spring may be caused by electrical failures or mechanical issues like wheel and steering misalignment. If broken, this will cause a warning message or warning light, affecting the steering wheel’s button functions. 
• ⚠️ Faulty Wiring – Faulty wiring will disrupt signals to other systems. If the airbag module detects an open circuit line, it will send the user a warning message or light.
• ⚠️ Defective Airbag Igniter – A defective igniter may malfunction due to corrosion, dirt, rust, age, or electrical failure, leading to an airbag not being deployed if a collision happens. In some cases, a faulty airbag igniter will deploy the airbag at any time. 
• ⚠️ Faulty Airbag Module – A faulty airbag module will malfunction and not operate properly, leading to a communication error in the SRS system.  

🛠️ Pro Tip: Use an OBD-II scanner to check for error codes related to the issue.

Common Symptoms 

• Warning Message or Warning Lights On – The SRS is the safety feature of the vehicle that will save lives. If one of the SRS system components is faulty, it will immediately send a signal or message to the user, urging them to inspect it as soon as possible for safety reasons. 
• No Horn – If your clock spring is faulty, your horn will not make a noise due to a bad connection. 
• Steering Buttons are not Working – The connection wire of your steering buttons is connected to the clock spring.  If the part is defective, your steering buttons may not function. 

🔧 Troubleshooting 

SRS malfunctions are often caused by low voltage or dead batteries, working on the electrical system without disconnecting the battery, damaged clock springs, or issues with the SRS control unit.

1. Disconnecting Airbag Wires

Disconnecting components such as the stereo, seat, airbag, and sensor of the airbag system without disconnecting the battery is among the most common reasons that Volvo SRS warning comes up.

The good news is that you don’t need to take the car to the dealer to reset the SRS Airbag warning message. While you can’t reset airbag warnings with a generic OBD2 scanner or disconnect the battery, you can use a Volvo scanner to clear the airbag module’s fault code. Remember to always disconnect the battery when you work on the electrical system.

2. Instrument Cluster / DIM

The Driver Information Module (DIM), which Volvo calls the instrument cluster, may fail when the speedometer does not work.

You can learn more about this problem here: Volvo Instrument Cluster DIM Problems.

3. Previous Accident

If your Volvo was involved in an accident, the airbag light might come on, even if it is minor. An accident event will be stored in the SRS module. After a car accident, items such as seat belt tensioners and airbags deploy and must be replaced.

After replacing the airbags and seat belt tensioners, you must either replace or reset the SRS module. Replacing the SRS module costs $1000+, but a less expensive fix would be to remove it from the center console and send it for repair to a specialist. Check out these places that offer Volvo SRS Airbag module repair on eBay.

4. Dead Battery

Volvo SRS airbag message can also come on when you replace the battery or jump-start the car if your battery dies.

The Volvo SRS module does not operate properly at low voltage. Therefore, it stores a low-voltage fault code in the SRS module, triggering the SRS Airbag Service Urgent message. Codes related to the low battery can be cleared with a Volvo scanner. See the instructions in the previous section on resetting the Volvo airbag light.

5. Seat Occupant Weight Sensor (OWS)

An occupant weight sensor (OWS) is installed in the passenger seat cushion. It detects the weight of the passenger on the front seat. A passenger seat sensor is sometimes the culprit. Another frequent problem is that the wires under the seat connecting to the passenger OWS sensor get damaged or unplugged. Inspect the yellow connector under the passenger seat.

6. Seat belt buckle

The seat belt buckle has a small sensor that detects whether the seat belt is in use. If the wires to the seat belt sensor (a microswitch) become disconnected, you will receive a fault code indicating an open circuit to the seat belt buckle. You can use a multimeter to test the switches in the seat belt buckle.

7. SRS Module

The supplemental Restraint System (SRS) control module is behind the shifter’s center console. It can fail, especially if it is exposed to liquid, but this is not a common issue.

8. Software Issue

The SRS software may need to be updated. A Volvo dealer can only perform this. Call your Volvo dealer and ask if there is a recall for the airbag module or a software update. Depending on how old your Volvo is, you may get the update free of charge.

9. SIPS Unit

The Volvo Side Impact Protection System (SIPS) is a passive safety system designed to protect against injury in a side collision. Although it is rare, the SIPS unit can fail and may need to be replaced.

Before taking your car to a mechanic, try these steps:

1. Airbag Recall – Volvo has had an airbag recall from 2001 to 2009 for certain models, such as S60, S80, V70, and XC70. Visit the website to see if your vehicle is affected by this recall.
2. Use an OBD-II scanner to Check the DTCs Related to the Issue – Scanning your Volvo will help you determine which part of the SRS system is causing the warning light or message. Try to delete these codes first and scan the system again to check if the issue is still present.
3. Check Battery and Charging Condition – If your car has a low voltage (below 12.4 volts), the SRS airbag warning light might appear on your dashboard. Car batteries degrade over time and must be replaced every 3-5 years. If you are still experiencing battery-related issues after replacing your battery, your alternator might be malfunctioning.
4. Check the Wires and Connectors – Wires become brittle and weak over time because of aging or harsh driving conditions. Mechanical movements may also damage the wires, especially the wires on the driver and passenger seats.
   Remove the negative battery terminal before inspecting these wires to prevent further electrical damage.
5. Check the Clock Spring – Try to press your horn and check all the steering buttons to see if they are functioning. If one of these is not functioning, there is a high possibility that the clock spring is causing the issue.
   Remove the negative battery terminal before inspecting or replacing the clock spring.
   • How to Remove and Refit the Clock Spring – Before removing the steering wheel parts, make sure the wheels and steering wheel are straight. Remove the clock spring. Get the new part, count the rotation, and center it before installing. Make sure all the connectors are correctly connected. Remove the negative battery terminal before doing the job.
6. Inspect the Impact Sensors– Look for signs of damage, dirt, corrosion, or loose pins or connections that may lead to the issue. If the impact sensors are malfunctioning, it might appear as a DTC when scanning the system.
   Remove the negative battery terminal before inspecting the sensors to prevent electrical damage.
7. Inspect the Airbag Igniter– Clean the airbag igniter and and check for any sign of damage, dirt, corrosion, or loose pins or connections that may lead to the issue.
   Remove the negative battery terminal before inspecting it to prevent any electrical damage.
8. Inspect the SRS Module – Look for any sign of burning, corrosion, or damage on the module, as this may be the reason for the error message.
   Remove the negative battery terminal before doing the job.
9. Outdated Software Version – Check for a software update. The update may solve the issue. Most OBD-II scanners are not capable of updating software, so you will have to visit your after-sales dealership.
