An automobile diagnostic is a systematic process used to identify problems in a vehicle’s mechanical, electrical, and electronic systems. Modern diagnostics combine computer-based analysis with physical inspection and testing. Below is a detailed, step-by-step description of how a professional automotive diagnostic is typically performed.
When a warning light pops up or your car just doesn’t feel “right,” the uncertainty can be the most stressful part. At Mobile Mike’s Automotive Repair, we take the guesswork out of the equation with professional, high-tech diagnostic services that come directly to you.
Modern vehicles are essentially rolling computers. That’s why we use advanced diagnostic equipment to “talk” to your car’s onboard systems. Whether it’s a stubborn Check Engine Light, an ABS glitch, or a mysterious electrical drain, we don’t just clear codes—we find the root cause.
Comprehensive System Scan: A full health check of your vehicle’s computer modules.
Sensor & Data Analysis: Monitoring real-time data to see exactly how your engine and transmission are performing.
Expert Inspection: A physical “eyes-on” verification by a skilled technician to confirm the computer’s findings.
Transparent Reporting: You’ll get a clear explanation of what’s wrong, why it happened, and a detailed estimate for the repair.
Diagnostic Call: $125
When I arrive at your location, I’m not just reading codes; I’m performing a deep-dive into your vehicle’s health. Here are the specific systems we can analyze:
Check Engine Light (MIL): Identifying the exact fault code and the underlying mechanical or sensor failure.
Fuel System Analysis: Testing fuel pressure, injectors, and pump health to solve stalling or poor gas mileage.
Ignition System: Checking spark plugs, ignition coils, and timing for misfire issues.
Emissions & Exhaust: Testing oxygen sensors, EGR valves, and catalytic converter efficiency.
Battery & Charging System: Testing the alternator, starter, and battery health to ensure you aren’t left stranded.
Advanced Computer Modules: Diagnostics for the ECM (Engine Control), TCM (Transmission), and BCM (Body Control) modules.
Electrical Parasitic Draw: Finding those “hidden” drains that kill your battery overnight.
Wiring & Grounds: Tracing broken wires or poor grounds that cause flickering lights or intermittent glitches.
ABS & Traction Control: Identifying why your Brake or Traction lights are staying on.
Airbag (SRS) Systems: Checking the safety sensors and clock springs to ensure your protection systems are active.
HVAC Systems: Diagnosing climate control issues, from faulty blend doors to AC compressor engagement.
Window & Lock Actuators: Pinpointing why your power windows or door locks have stopped responding.
Many shops charge a "diagnostic fee" just to plug in a scanner. At Mobile Mike’s, my $125 Diagnostic Call includes the scan, the labor to physically inspect the components, and a professional recommendation for the fix.
A parts store scanner only provides a trouble code, which is just a starting point. It tells you what part is “sad,” but not why. For example, an Oxygen Sensor code could mean a bad sensor, a vacuum leak, or a wiring issue. My professional diagnostic includes a full system analysis to find the root cause, ensuring you don’t waste money on parts you don’t actually need.
Most diagnostic calls take between 45 and 90 minutes. This gives me enough time to hook up my advanced equipment, perform a visual inspection, and test specific components (like sensors or wiring) to confirm the failure.
The $125 Diagnostic Call covers my travel to your location, the use of professional-grade diagnostic software, and the labor required to pinpoint the fault. Once the problem is identified, I provide a separate estimate for the repair labor (at my $95/hr mechanical or $110/hr electrical rate) and any necessary parts.
I can still help! Many issues, like a failing fuel pump or a worn suspension component, won’t always trigger a light. My “Diagnostic Call” includes a test drive and data logging to see what the car is doing while it’s in motion.
Yes. My equipment is compatible with most domestic and import vehicles. Whether you’re in Grants Pass, Selma, or out in Williams, I bring the tech to you.
