SRS & Airbag Systems
in Diamond Bar
SRS diagnostics and setup for every customer type
SRS and airbag system service in Diamond Bar covers crash data retrieval, module programming, and OCM setup after collision work. Mobile for drivers, dealerships, fleets, and shops, with Pomona and the Inland Empire on the same routes.
What Is the SRS / Airbag System?
The Supplemental Restraint System (SRS) is the vehicle’s network of safety components that work together during a collision to protect occupants. It includes the airbag control module (ACM), front and side airbag inflators, seat belt pretensioners, the occupant classification module (OCM), clock spring, and an array of crash sensors positioned throughout the vehicle.
After any deployment event, the airbag control module stores crash data and locks out the system until the data is cleared or the module is replaced and programmed. Seat belt pretensioners and deployed airbags must be replaced, and the entire SRS system must be restored to OEM specifications before the vehicle can be returned to service. Each replacement component must be correctly installed, programmed, and verified.
We provide complete SRS system restoration services, from crash data retrieval and module programming to OCM configuration and full system verification, following OEM procedures for every vehicle platform we service.
SRS Service Capabilities
What We Cover
We provide complete SRS and airbag system restoration services following OEM procedures for domestic and import vehicles throughout Southern California.
Airbag Module Programming & Replacement
OEM programming for replacement airbag control modules (ACM), including software installation, VIN writing, variant coding, pairing, and post-programming system initialization and verification.
Crash Data Retrieval
Complete extraction of crash event data stored in the airbag control module for insurance, legal, and repair documentation, plus evaluation of whether the module can be reused.
SRS Scan & Warning Light Diagnosis
Full diagnostic scan of SRS components to identify active and stored faults, then investigate the specific fault code and repair path needed to clear the airbag warning light.
Occupant Classification Module (OCM)
OCM programming, configuration, and seat mat calibration after seat or airbag system repairs so passenger airbag enable/disable logic operates correctly.
Pretensioner & Clock Spring Diagnosis
Diagnosis of seat belt pretensioner faults after collision or deployment, plus clock spring (spiral cable) faults that can trigger SRS warning lights and disable airbag or steering controls.
Post-Deployment Restore & Wiring
Complete SRS restoration after deployment, module programming, component verification, wiring and connector inspection, and a full system scan before the vehicle is returned to service.
When Are SRS / Airbag System Services Needed?
SRS services are required after any collision event involving airbag deployment, as well as for diagnosis and repair of active SRS faults or warning lights.
After Airbag Deployment
Any collision that deploys airbags requires complete SRS system restoration. The airbag control module locks after deployment and must be replaced and programmed, along with all deployed inflators and triggered pretensioners.
Collision Repairs
Even in collisions where airbags did not deploy, crash sensors, wiring, and SRS components can be damaged and must be inspected, diagnosed, and repaired as part of the complete collision repair.
SRS Warning Light
An illuminated airbag warning light indicates a fault in the SRS system that must be diagnosed and repaired. The vehicle should not be driven until the fault is identified, an active SRS fault can prevent airbag deployment in a collision.
Module Replacement
Any replacement of the airbag control module or occupant classification module requires OEM programming before the system will function. An unprogrammed replacement module will leave the SRS system inoperable.
Seat Belt System Faults
Seat belt pretensioner faults, retractor issues, and buckle tensioner codes require SRS system diagnosis. Triggered pretensioners must be replaced and verified before the SRS system will clear.
What Does an SRS Scan Find?
Select a topic to see what a complete SRS diagnostic scan checks, ACM, OCM, pretensioners, clock spring, crash data, sensors, and communication faults, before codes are cleared.
Airbag Control Module
A full SRS scan reads the airbag control module (ACM) for active and stored fault codes that keep the restraint system locked out or the warning light on. After deployment, the ACM stores crash data and enters a locked state that prevents re-use. Scan results guide whether the module must be replaced and programmed with OEM software, including VIN write, variant coding, and system initialization, before the SRS system will function.
Occupant Classification
The scan checks the occupant classification module (OCM) and related seat mat faults that affect passenger airbag enable/disable logic. After seat replacement, collision repairs involving the seat, or seat mat replacement, OCM faults commonly remain until the module is reprogrammed and the seat mat is calibrated so the system detects occupant weight and position correctly.
Pretensioners
Seat belt pretensioner circuits are scanned for deployed, faulty, or improperly connected conditions after a collision or deployment event. Triggered pretensioners must be replaced and verified; retractor issues and buckle tensioner codes will keep the SRS system from clearing until those faults are corrected and confirmed on a follow-up scan.
Clock Spring
Clock spring (spiral cable) faults commonly appear after steering repairs and can trigger the SRS warning light while disabling airbag, horn, and steering wheel control functions. An SRS scan identifies these codes so the clock spring can be diagnosed, replaced if needed, and verified before the restraint system is marked ready.
Crash Data
Crash data, also called event data or deployment data, is information recorded by the ACM at the moment of a collision, including vehicle speed, delta-V, seat belt status, airbag deployment sequence, and sensor readings. Specialized retrieval documents these parameters for insurance, legal, and repair records. Stored crash data from a prior collision can also keep the warning light on, and the module cannot be reused after storing crash data.
Crash Sensors
Crash sensors positioned throughout the vehicle are included in a complete SRS diagnostic scan. A faulty or disconnected crash sensor is a common cause of the airbag warning light, and even collisions without deployment can damage sensors that must be inspected and repaired as part of the collision repair before the system is returned to OEM specifications.
Communication Faults
SRS wiring harnesses, connectors, and sensor circuits are checked for damage, corrosion, or open/short conditions that interrupt module communication. Collision damage or improper prior repairs can leave communication faults that keep components offline. Low battery voltage events can also set SRS codes. The scan identifies the specific fault so the underlying wiring or power issue is repaired, never cleared without fixing the cause.
Vehicle Makes We Service
SRS and airbag system service support for domestic, European, and Asian vehicle manufacturers.
Service Process
Every SRS and airbag system service follows a structured process, from on-site diagnosis through OEM programming and full system verification.
Arrive On-Site
Mobile technician arrives at your collision center, repair shop, or dealership with OEM-level programming and scan equipment, no vehicle transport required.
Full SRS System Scan
Complete diagnostic scan of SRS components, ACM, OCM, pretensioners, clock spring, and crash sensors, to identify all active and stored faults.
Crash Data & Evaluation
Crash event data is retrieved from the ACM when needed for documentation and to determine whether the module must be replaced or can be restored.
Module Programming
Replacement ACMs and OCM units are programmed with OEM software, including VIN writing, variant coding, configuration, and system initialization.
Component Verification
Deployed inflators, triggered pretensioners, clock spring, seat mat calibration, and wiring repairs are verified so each replacement component is correctly installed.
Final System Scan
A complete post-service SRS scan confirms all components are communicating, no fault codes remain, and the restraint system is fully operational before delivery.
