Diagnostics for Domestic & European Vehicles

We invest in professional-grade tools that match or exceed dealer capability for the platforms we support. No generic code readers.

What We Diagnose

  • Check-engine, ABS, airbag, and body control module codes with bi-directional control
  • Intermittent electrical issues and network (CAN/LIN/FlexRay) faults
  • Module programming, coding, adaptations, and key programming (where authorized)
  • Sensor signal integrity testing (scope-level when required)
  • European platforms: BMW, Mercedes, Audi, VW, Porsche, Land Rover / Range Rover, Jaguar, Volvo
  • Domestic: Ford, GM, Stellantis, Toyota/Lexus, Honda/Acura, Hyundai/Kia, Nissan

Our Approach

We treat diagnostics like engine building: methodical, data-driven, and never guesswork. Every diagnosis includes:

  • • Full system scan with freeze-frame and pending codes
  • • Live data graphing and comparison to known-good values
  • • Component testing before replacement
  • • Clear explanation of root cause, not just “codes found”
  • • Fixed-price repair quote before any parts are ordered

RV & Marine Electrical, Engine & Drivetrain

Coach and marine 12V/120V systems get treated like any other wiring harness: trace it, test it, and verify it instead of guessing. We bring the same methodical diagnostic approach to marine engines and drivetrains, on the trailer, on the lift, or on the hard.

Engine & drivetrain service is performed above the waterline or with the vessel hauled out, whether on a trailer, a lift, or in a boatyard. We do not perform in-water diving or underwater running gear work. For hull, rigging, or in-water haul-out logistics, we'll help point you to the right specialist.

Equestrian & Farm/Ranch Service

Serving the Ojai Valley's horse properties and Ventura County's working ranches & ag operations. Your tow rig, trailer, and equipment kept road-ready without a trip off the property.

  • Battery, starting, and charging system service in remote/rural locations

On-property visits mean less downtime moving equipment and no arranging a flatbed for routine service.

Performance, Tuning & Track Prep

We perform fluid upgrades (high-temp brake fluid, synthetic gear oil), cooling system improvements, brake system optimization, suspension inspection/setup notes, and full pre-event safety inspections. Track cars receive the same methodical, data-backed approach we apply to every job. I also do ECU tuning with HP Tuners and standalone ECUs. See ECU tuning.
