Car Diagnostic Software That Connects Findings to Repair Orders
Log OBD2 codes. Attach repair recommendations. Connect diagnostics to work orders. Mechanics keeps every finding on file with customer-facing explanations that reduce disputes.
Why Diagnostics Go Missing
A technician plugs in a scanner. It throws a code: P0430 (catalyst system efficiency below threshold). The tech scribbles the code on the work order. They tell the customer "your catalytic converter might be going out" but don't know for sure. The customer doesn't want a $1,000+ repair without proof. You lose the job. Six months later, a different tech at a different shop fixes it and gets the money.
Paper diagnostics and sticky notes don't connect the code to the symptoms, test results, or repair recommendation. Customers see a random number and don't trust it. When a second tech reads the same code months later, you re-diagnose instead of building on previous findings. Data gets lost. Work gets repeated. Money gets left on the table.
Mechanics treats diagnostics as first-class work. Every finding—DTC code, symptoms, test results, tech notes—gets stored permanently, attached to the vehicle, and linked to repair orders. When a customer questions a diagnosis, you show them a complete file with evidence. When a customer returns months later with the same issue, you pull up the previous diagnosis and build on it. Disputes drop. Confidence goes up.
The Diagnostic Workflow in Mechanics
Mechanics simplifies the complete diagnostic workflow from scan to customer approval. Record findings as you discover them. Attach evidence (test results, photos, videos). Build a professional recommendation. Show the customer exactly what you found. They approve and authorize repair. The diagnosis is linked to the work order. You build a permanent vehicle diagnostic history.
Scan & Log DTC Codes
Plug in an OBD2 scanner. Record codes (P0430, P0101, etc.), freeze frame data, and live sensor readings. Everything syncs to the vehicle's diagnostic file in Mechanics.
Multiple DTC codes per diagnostic
Freeze frame capture
Live sensor data logging
Document Symptoms & Tests
Log what the customer reported (rough idle, check engine light, poor acceleration). Add your testing: visual inspection, component tests, fuel pressure readings.
Customer-reported symptoms
Component test results
Pressure/voltage readings
Visual inspection notes
Build Repair Recommendation
Based on codes and testing, recommend repairs in order of probability. Include cost estimate and why you think this will fix the issue.
Ranked repair causes (most to least likely)

Show Customers Evidence, Not Guesses
When a tech says "your catalytic converter is bad," customers don't believe it without proof. Mechanics generates customer-facing diagnostic reports that explain findings in plain English. "Your check engine light is triggered by code P0430, which means your catalytic converter is not converting emissions efficiently. This usually happens because of upstream oxygen sensor failure or rich fuel mixture."
Customers see the actual code, test results, and plain-language explanation. They understand why the repair is needed. Disputes drop. Approval rates jump from 40% to 70%+. You stop defending your diagnosis and start closing sales.

Sample Customer Report
CODE DETECTED
P0430: Catalyst System Efficiency Below Threshold
WHAT THIS MEANS
Your catalytic converter is not converting pollutants efficiently. This is usually caused by a faulty oxygen sensor or the converter becoming saturated.
SYMPTOMS YOU MAY NOTICE
Check engine light (active), possible reduced fuel economy, rough idle
OUR RECOMMENDATION
Replace catalytic converter: $850-$1,200
Parts + labor, 2-3 hours
For Shops Tired of Diagnostic Disputes
General Auto Repair Shops
You do diagnostics on every service. Mechanics stores findings permanently so you build diagnostic intelligence over time and close more approvals.
Diagnostic Centers
Diagnostics are your entire business. Mechanics gives you professional reports that justify your labor charge and turn browsers into paying customers.
Specialty Shops (Engine, Transmission, Electronics)
Complex diagnostics are your expertise. Mechanics documents your work so customers understand the complexity and competitors can't steal your findings.
Dealerships
You need diagnostic records integrated with warranty claims and recalls. Mechanics tracks every finding linked to the vehicle's complete service history.
The Impact of Professional Diagnostic Records
70%+
Approval Rate
Customers who see detailed diagnostic reports approve 70%+ of recommendations vs. 40% who hear 'your converter is bad.'
60%
Fewer Disputes
When customers see codes, test results, and photos, disputes drop by 60%. You stop defending and start selling.
Zero
Lost Diagnostics
Every finding is stored permanently. You never re-diagnose the same issue twice or lose data when a tech leaves.
