2008-2015 Jaguar XK Passenger Airbag: SRS Light, Recalls, and Replacement Guide

Symptoms of a Faulty Instrument Panel Airbag

The most common and immediate sign of a problem within the airbag system is the illumination of the SRS warning light on your instrument cluster. Unlike other warning lights, a problem with a single component, like the passenger airbag, will disable the entire SRS system as a safety precaution.

• SRS Warning Light: The light will typically illuminate for a few seconds as part of a self-check when you start the car, and then turn off. If the light stays on, or comes on while driving, it indicates the RCM has detected a fault. When the SRS light is on, you should assume none of the airbags will deploy in a collision.
• Passenger Airbag Off Light: The XK is equipped with a passenger occupant classification system. If this system malfunctions, it may incorrectly classify the passenger seat as empty or occupied by a small child, disabling the airbag and illuminating the 'Passenger Airbag Off' indicator even when an adult is seated.
• Diagnostic Trouble Codes (DTCs): A professional scan tool is required to read SRS codes. Common codes related to the passenger airbag include:
  • B0028 / B0029: These codes point to a problem in the passenger airbag deployment circuit, such as low or high resistance. This is often caused by a wiring issue, a faulty connector, or a problem with the airbag module (squib) itself.
  • B2291: This code indicates a fault with the passenger occupant classification sensor, the pressure pad in the seat cushion.
  • Flash Code 17: On some models, the SRS light will flash a code before staying on solid. A sequence of one flash, a pause, then seven flashes (Code 17) points to a fault in the Passenger Occupant Position Sensors.

Major Safety Recall: Takata Airbag Inflators

The 2008-2015 Jaguar XK falls within the timeframe of the largest automotive recall in history, involving defective airbag inflators made by Takata. Jaguar was one of 33 manufacturers affected. The issue specifically concerns the passenger-side front airbag. Over time, the chemical propellant in the inflator can degrade, especially with exposure to heat and humidity. In a crash, a defective inflator can rupture, sending sharp metal fragments toward vehicle occupants, which can cause serious injury or death.

While many sources confirm the recall for 2009-2015 Jaguar models like the XF, owners of an XK from this period should immediately check if their specific vehicle is included. The repair is performed for free by any authorized Jaguar dealer.

Other Common Faults

Forum discussions with XK owners reveal other common triggers for the SRS light that may not be the airbag itself:

• Low Battery Voltage: Jaguars are notoriously sensitive to battery health. If the battery voltage drops below a certain threshold (e.g., 9.5 volts), it can trigger an SRS fault code. This should be the first thing you check, as a new battery is a much simpler fix.
• Clock Spring: This component, located behind the steering wheel, can fail and cause an open circuit to the driver's airbag, but it can sometimes trigger a general SRS fault. A failing clock spring often presents other symptoms like the horn or steering wheel buttons not working.
• Connectors Under Seat: Loose or corroded electrical connectors under the front seats for the seat belt pretensioners or occupant sensors are a very common cause of an intermittent SRS light.

Buying a Used Instrument Panel Airbag

Given the high cost of a new OEM airbag, a used, non-deployed OEM unit from a reputable auto recycler is a viable and safe alternative. Aftermarket airbags are not considered a safe or legitimate option.

Inspection Checklist:

• Verify the Source: Only purchase from a certified and reputable automotive recycler who guarantees the part is non-deployed and has been handled and stored correctly.
• Check for Recall Status: It is illegal and unsafe to install a recalled airbag. While difficult for a buyer to verify independently, a reputable seller should be able to confirm the source vehicle was not part of the Takata recall. Do not purchase if there is any doubt.
• Inspect Connectors: Ensure the electrical connectors and wiring pigtails are intact, with no cut wires, corrosion, or damaged pins.
• Examine the Housing: The airbag module's plastic or metal housing should be free of cracks, deep scratches, or signs of water damage.
• Confirm Part Numbers: Match the OEM part number exactly to your original unit. Verified part numbers for this application include C2P13451 and 6W83-044A74-AE.

Post-Replacement System Reset

After the new airbag is physically installed, the SRS system requires a reset. If the original fault was due to a component failure, the stored 'soft code' can often be cleared by a professional-grade scanner. However, if the airbag was replaced after a collision, the Restraints Control Module (RCM) will have stored 'hard codes' or crash data. This data cannot be cleared with a standard scan tool. The RCM must either be replaced or sent to a specialized service that can perform an EEPROM reset to restore it to factory condition.
