Expert Automotive Electrical Diagnostics
Modern vehicles depend on complex electronics—computers, modules, sensors, and miles of wiring—all communicating constantly. One faulty sensor or broken wire can cause major performance issues.
At Tried and True Auto, we use dealer-grade scan tools, oscilloscopes, and data analyzers to identify even the most difficult electrical faults. Our diagnostic process goes beyond basic code scanning to pinpoint real causes, not guesses.
We diagnose and repair all types of electrical problems, including:
-
Lighting systems: Headlights, brake lights, interior illumination, and LED circuits
-
Charging and starting systems: Alternators, batteries, ignition circuits, and grounds
-
Body electronics: Power windows, mirrors, locks, seats, and sunroofs
-
Communication and control modules: BCM, PCM, TCM, and HVAC control units
-
Sensors and actuators: ABS, airbag, throttle, cam/crank sensors, and more
-
Infotainment and radio systems: Audio, Bluetooth, and screen or amplifier faults
-
Automatic doors and remote entry systems

Today’s vehicles often require module programming, key coding, or software updates when a part is replaced. Tried and True Auto offers dealer-level programming and reflash services for most makes and models—including GM, Ford, Chrysler, Nissan, Toyota, and more.
We handle:
