If you are a Jaguar owner and have noticed the airbag/SRS light on your dashboard, you may be wondering what could be causing it to stay illuminated. This warning light indicates an issue with the airbag system, which can be a potential safety concern. In this article, we will discuss the common causes & symptoms of the airbag/SRS light and provide you with some solutions to fix the issue.
What does the airbag / SRS light mean on a Jaguar?
The illumination of the Airbag/SRS warning light is a sign of a system malfunction, which can lead to airbags either not deploying in a critical situation or deploying unexpectedly, potentially causing serious harm. Moreover, when this warning light turns on, it records a fault code that can be examined using an airbag scanner. There could be numerous reasons for the airbag light activating, including a malfunctioning clock spring, deployed airbags, and a defective SRS module, which will be further explained below.
Can You Still Drive Your Jaguar with Airbag Light On?
While the airbag light won’t directly impact the functionality of your vehicle’s driving operation, it’s generally advised not to operate the vehicle when this light is on. This is due to the inherent risks involved: airbags might fail to activate during a collision or deploy spontaneously, endangering the vehicle’s occupants and driver. The airbag system is a protective measure for the driver and passengers in the case of a car crash. As such, it’s crucial to address this issue as soon as possible before driving your vehicle again.
When the airbag/SRS (Supplemental Restraint System) light comes on in a Jaguar, it indicates a fault within the system. Several symptoms may accompany the airbag/SRS light, which can vary depending on the nature of the fault.
- Illuminated Airbag Warning Light: The most obvious symptom is the illumination of the airbag warning light on the dashboard. This light generally stays on when the ignition is turned on.
- Intermittent Flashing of Airbag Light: Sometimes, the warning light flashes or flickers intermittently, suggesting a potential problem.
- Failure in Other Safety Systems: Since the SRS system is interconnected with other safety features in your car, you may also notice other warning lights illuminating your dashboard, such as the seatbelt warning light.
- Error Messages on the Display: Modern Jaguar vehicles can provide specific error messages on the display panel indicating faults within the system.
- Horn not working: Some Jaguar models have an airbag integrated into the steering wheel. When there is a fault in the airbag system, the horn may not work, as the module is designed to disable the circuit that activates the horn.
- Traction Control and ABS Lights: In some cases, the airbag/SRS light may trigger other warning lights on the dashboard, such as the traction control and ABS lights, as these systems are also connected to the same network of sensors and control units as the airbag system.
The most common problem that triggers the airbag on Jaguar vehicles is the failure of the clock spring that connects the airbag control units to the driver’s airbag. Another common problem is the failure of the passenger occupant weight sensor.
Weak or Dead Battery
If the battery voltage falls below 9.5 Volts, it will often trigger the airbag light. In that case, the SRS control module might register a fault code in its memory, causing the airbag/SRS warning light on the dashboard to activate. The airbag system requires a stable voltage to operate correctly. However, in certain instances, specialized diagnostic tools may be necessary to erase the fault code manually. It’s critical to recognize that a depleted or completely dead battery can also disrupt other vehicle systems, such as the engine management system, transmission control module, and various electronic systems. You may also get ABS, traction control, stability control, and no-start condition. Consequently, it’s advised to get the battery tested and replaced if needed to prevent additional complications with the vehicle’s electronic systems.
Faulty Clock Spring
The clock spring is a vital component that bridges the steering wheel to the vehicle’s other electrical systems, maintaining electrical connections even while the steering wheel turns. If this clock spring malfunctions, it can interrupt the electrical connection to the airbag and ABS systems, triggering the warning lights. In some scenarios, the horn might cease to function, as it, too, is linked via the clock spring. Replacing a defective clock spring calls for specific expertise and tools. Before removing and installing a new clock spring, disconnect the negative battery terminal first and wait at least 15 minutes. This precaution helps to avert inadvertent airbag deployment during the process.
Faulty Airbag Control Module
The airbag/srs control module oversees the system’s components, including airbags, seat belt pre-tensioners, and weight and crash sensors. If this module malfunctions, it may lead to the airbags deploying unpredictably, failing to deploy during a crash, or deploying with inadequate force. These situations can potentially result in severe injuries or fatalities in a collision. One of the most common reasons for airbag module failure is water damage. Also, you can use an airbag scanner to read fault codes.
If the airbags have been activated due to an accident, it is necessary to reset the SRS module to restore its functionality. Resetting the airbag/SRS module can resolve minor issues; however, replacing the module with a new one may be necessary for more serious problems.
Faulty/Defective Crash/Impact Sensors
The crash or impact sensors notify the airbag control module during a vehicle collision, triggering the airbags to deploy. If these sensors fail, the airbag warning light will turn on, and an error code will be registered on the srs module. A common reason for sensor failure might be removing these devices during front-end vehicle repairs, which can cause damage or promote corrosion. You’ll require an airbag scanner to read the error code to identify a malfunctioning sensor. Before proceeding with sensor replacement, we advise checking the integrity of the wiring.
Lose, Corroded, & Damaged Wiring
The airbag or supplemental restraint system (SRS) relies on wiring and connectors to facilitate communication between its various elements and sensors. If the wiring gets loose or suffers from corrosion, it can disrupt the signal transmission, causing the airbag warning light to turn on. The wiring can deteriorate over time due to heat or repeated bending or pinching, which could result in a broken wire. Although pinpointing defective wiring can be challenging, a scanner can identify which sensor is not working properly, allowing for closer inspection of its associated wiring.
In the event of a collision leading to the deployment of your vehicle’s airbag, it becomes essential to immediately replace the airbags since they’re designed for single use only. Post-replacement, resetting the airbag control module to ensure it functions effectively is necessary. Detecting a triggered airbag isn’t complicated; you only need an airbag scanner to reveal which airbag has been deployed or is still to be replaced.
Deployed Seat Belt Pre-tensioner
The seat belt pre-tensioner is a critical part of the Supplemental Restraint System (SRS), designed to quickly pull back the seat belt during a crash, lowering the likelihood of harm. It self-tightens to help keep the passengers and driver from colliding with the inside of the car. It’s crucial to understand that once a seat belt pre-tensioner has been deployed, it can impact the functionality of other safety mechanisms in the vehicle, like airbags.
Occupancy Passenger Sensor
The occupancy passenger sensor is the one that detects the weight, whether an adult or a kid is sitting in the passenger seat. The sensor will send a signal to the srs module, enabling or disabling the airbags from deploying the airbags. Airbags can be dangerous to kids. That’s why it will be disabled if a kid is seated in the passenger seat. To diagnose the occupancy passenger sensor, you will need an airbag scanner to read the stored fault codes. We also recommend inspecting the sensor’s wiring before replacing the occupancy passenger sensor.
