⚠️ Safety Warnings

Important safety information - read before proceeding

•Always disconnect the battery before working on the SRS system to prevent accidental airbag deployment.
•Handle airbag components with care to avoid unintended deployment.

Symptoms

•SRS warning light illuminated on the dashboard
•Airbags not deploying during a simulated fault
•Diagnostic trouble codes (DTCs) related to airbags present when scanned
•Inoperative seatbelt pretensioners
•Malfunctioning crash sensors

Diagnostic Steps

1
Scan the vehicle's OBD-II system using an appropriate diagnostic scanner to retrieve any SRS-related error codes.
2
Inspect the vehicle's battery and ensure it is properly charged, as low voltage can affect the SRS system.
3
Check all connections and wiring related to the airbag system, including connectors under the seats and at the airbag modules.
4
Test the integrity of the crash sensors for faults or damage.
5
Verify the status of the seatbelt pretensioners and ensure they are functioning correctly.
6
Inspect the airbag control module for any signs of damage or corrosion.

Solution

Solution

1. Preparation

Tools Required: OBD-II scanner, multimeter, socket set, torque wrench, wiring harness repair tools.
Disconnect the vehicle's negative battery terminal to ensure safety when working on the SRS system.
Allow the vehicle to sit for at least 10 minutes to discharge any residual power.

2. Retrieve and Analyze DTCs

Connect the OBD-II scanner and retrieve SRS codes.
Note the codes and refer to the vehicle service manual for specific troubleshooting related to those codes.

3. Repair or Replace Faulty Components

Wiring and Connectors:
- Inspect and repair any damaged wiring or loose connectors identified during the diagnostic steps.
- Use a multimeter to check for continuity in the wiring.
Crash Sensors:
- If sensors are found faulty, disconnect the wiring harness, unbolt the sensor, and replace it with a new one.
- Torque the new sensor to the manufacturer’s specifications.
Airbag Control Module:
- If the airbag control module is defective, disconnect the battery again, remove the module from its mounting location, and replace it with a new module.
- Reconnect all wiring and ensure connections are secure.

4. Reset the SRS System

Reconnect the negative battery terminal.
Use the OBD-II scanner to clear all SRS codes and reset the system.
Perform a final check to ensure the SRS warning light is extinguished.
