Professional Scanning & Fault Finding
When warning lights come on, engines hesitate, or electrical gremlins appear, you need accurate diagnostics—not guesswork. At Sonter Automotive, we combine specialist tools with expert technicians to pinpoint faults fast and fix them right.
What We Use (Why It Matters)

AECS Oscilloscope (latest generation)
For diagnosing complex electrical faults and intermittent issues that simple code readers miss.

Multiple OEM-level scan tools
To communicate with your vehicle’s systems (engine, transmission, ABS, airbags, A/C, TPMS) for precise, make-specific data.

Full test lane
To check steering, suspension, and brakes under load — ideal when handling, braking, or noise symptoms accompany dash lights.
