Modern vehicles are sophisticated machines with dozens of computer systems monitoring everything from engine performance to safety features. When something goes wrong—or after a collision—professional diagnostic testing is essential to identify problems and ensure all systems function correctly. At Autobahn Collision, we provide comprehensive car diagnostic testing services in New York using advanced equipment and expert technicians who understand today’s complex vehicle systems.
What is Car Diagnostic Testing?
Car diagnostic testing uses specialized computer equipment to communicate with your vehicle’s onboard systems, retrieving error codes, sensor data, and system status information. Modern vehicles contain multiple control modules that constantly monitor performance and safety systems, storing diagnostic trouble codes when they detect problems. Professional diagnostic testing interprets these codes, identifies root causes, and verifies repairs, ensuring your vehicle operates safely and efficiently.
Why Diagnostic Testing is Essential After a Collision
Even when a collision appears to cause only cosmetic damage, the impact can affect numerous electronic systems. Airbag modules may have deployed or stored crash data that needs clearing. Sensors for stability control, ABS, and traction systems can be damaged or knocked out of calibration. Wiring harnesses may be pinched, stretched, or severed, causing intermittent electrical problems.
Dashboard warning lights after an accident indicate systems that require attention before your vehicle is truly safe to drive. Some issues won’t trigger warning lights immediately but lurk as stored codes that can cause problems later. Professional diagnostic testing identifies all these issues so they can be properly repaired and documented for your insurance claim.
Systems We Diagnose and Test
Engine and Powertrain Systems
We diagnose engine performance issues, transmission problems, fuel system faults, emissions control malfunctions, and check engine light causes. These systems affect reliability, fuel economy, and emissions compliance.
Safety Systems
Our testing covers airbag systems and crash data, anti-lock braking systems (ABS), electronic stability control (ESC), traction control systems, and tire pressure monitoring systems (TPMS). Your safety depends on these systems functioning flawlessly.
Advanced Driver Assistance Systems (ADAS)
Modern vehicles include forward collision warning, automatic emergency braking, lane departure warning and lane keeping assist, blind spot monitoring, adaptive cruise control, and parking assistance systems. After collision repairs involving windshields, bumpers, or body panels, these systems must be recalibrated and tested.
Body Control Systems
We diagnose lighting systems, power window and door lock problems, climate control issues, instrument cluster faults, and infotainment system problems that can result from collision damage or electrical issues.
Suspension and Steering Systems
Electronic suspension systems, power steering modules, and wheel speed sensors all require diagnostic testing to ensure proper operation and identify impact damage.
Hybrid and Electric Vehicle Systems
High-voltage battery systems, electric motor controllers, regenerative braking systems, and charging systems require specialized diagnostic equipment and training. We have the tools and expertise to safely diagnose these advanced powertrains.
Our Diagnostic Testing Process
When you bring your vehicle to Autobahn Collision for diagnostic testing, we follow a systematic approach to identify all issues. We begin with a complete system scan using professional-grade diagnostic equipment that accesses all control modules in your vehicle, not just the engine computer.
We retrieve and document all diagnostic trouble codes, including current faults that trigger warning lights and stored codes that indicate intermittent problems or previous issues. Our technicians review live data streams from sensors and systems, checking for values outside normal parameters that indicate problems even when no codes are present.
Based on the codes and data, we perform targeted inspections of related components, wiring, and connections. We use advanced testing equipment including multimeters, oscilloscopes, and pressure gauges to verify our diagnoses and pinpoint exact failure points.
After repairs, we clear codes and perform verification testing to ensure the problem is truly resolved. We conduct test drives when appropriate to confirm systems operate correctly under real-world conditions. Finally, we perform a final system scan to verify no codes return and document the successful repair.
Post-Repair Verification
One of the most important uses of diagnostic testing is verifying that repairs were completed correctly. After collision repairs, we perform comprehensive diagnostic scans to ensure no warning lights are present, all systems communicate properly, crash data is cleared from airbag modules when appropriate, and ADAS calibrations are successful.
This verification testing protects you from discovering problems after you’ve left our shop. It also provides documentation for your insurance company that all repairs were completed to proper standards.
ADAS Calibration and Testing
Advanced Driver Assistance Systems have become standard on most new vehicles, but they require precise calibration after many types of repairs. Windshield replacement can misalign forward-facing cameras. Bumper repairs may affect radar sensors. Wheel alignment changes can throw off lane-keeping systems.
We have the manufacturer-approved calibration equipment and procedures to properly reset these systems. This includes static calibrations performed in our shop using specialized targets and dynamic calibrations that require test drives on specific road types. After calibration, we verify system operation with diagnostic testing to ensure everything functions as designed.
Check Engine Light Diagnosis
The check engine light is your vehicle’s way of telling you something needs attention. While some causes are minor, others indicate serious problems that can damage your engine or leave you stranded. Generic code readers from auto parts stores only provide basic code numbers without the detailed data needed for accurate diagnosis.
Our professional diagnostic equipment provides manufacturer-specific information, live data, freeze frame data showing conditions when the code set, and the ability to perform active tests of components and systems. This allows us to accurately identify the root cause rather than just replacing parts based on a code number.

No Unnecessary Repairs
We diagnose accurately so you only pay for repairs you actually need. We’ll explain if a code indicates a minor issue versus something urgent.
When You Need Diagnostic Testing
Beyond post-collision verification, there are many situations when diagnostic testing is essential. Warning lights on your dashboard indicate systems that need attention. Performance problems like rough running, poor acceleration, or reduced fuel economy often require diagnostics to identify causes.
Intermittent issues that come and go can be particularly frustrating, but diagnostic testing often reveals stored codes that point to the problem. Before buying a used vehicle, diagnostic testing can reveal hidden problems. Pre-inspection testing for emissions or safety compliance helps identify issues before official testing.
Even unusual noises, vibrations, or behaviors that don’t trigger warning lights may show up in diagnostic data as sensor values outside normal ranges.
Preventive Diagnostic Testing
Even without obvious problems, periodic diagnostic testing can catch issues early before they become expensive failures. Many problems begin as subtle changes in sensor data or intermittent codes that don’t yet trigger warning lights. Catching these early can prevent breakdowns and reduce repair costs.
We recommend diagnostic testing as part of regular maintenance, especially for vehicles with high mileage or those used in demanding conditions.
