When your car shows a fault code, you don’t need technical data — you need clarity.
Modern OBD2 systems and vehicle computer systems generate thousands of car fault codes, but they rarely explain what actually matters:
Is the issue serious? Can you keep driving? What should you fix first?
Most scan tool apps stop at displaying diagnostic trouble codes (DTC). They don’t help you interpret them. That is not the case with Carista:
AI Diagnostics by Carista transforms complex car fault codes into clear, actionable insights. Instead of just displaying diagnostic trouble codes (DTC), it explains what the issue means, how serious it is, what caused it, how to fix it, and what it may cost.
What are car fault codes?
Car fault codes, also known as diagnostic trouble codes (DTC), are alerts generated by your vehicle’s AI powered onboard computer when something is not working properly.
These codes come from your car’s OBD systems, which monitor:
- Engine performance
- Transmission operation
- Electrical components and sensors
- Emissions control systems
When a fault is detected — such as a sensor failure, wiring issue, or communication problem in the computer system — a code is stored and often triggers the check engine light.
Why they are hard to understand
A fault code like P0705 (often related to a transmission range sensor) or U0100 doesn’t explain:
- The root cause
- The severity of the issue
- What action you should take
Without clear fault explanations, you are left searching online or relying entirely on a mechanic.
How Carista AI Diagnostics works
AI Diagnostics by Carista simplifies car diagnostics troubleshooting into a fast and intuitive process:
Step 1: Scan your vehicle
Connect your Carista device and scan your car. The system retrieves car fault codes from the onboard OBD2 system.
Step 2: Tap AI insights
In Diagnostics, tap the AI insights icon next to the fault code you want to analyze.
Step 3: AI Analysis
The AI system processes the code using data from multiple vehicle manufacturers and OBD systems, then tailors the explanation to your specific car so you see what it actually means for your vehicle.
Step 4: Clear Explanation
You receive structured AI fault explanations that break down the issue into simple, easy-to-understand sections.
The entire process is fast, accurate, and designed for everyday users.
What information you get?
AI insights organizes diagnostics troubleshooting into clear, practical sections so you can act immediately.
1. Meaning of the fault code
You see exactly what the fault code means in plain language.
No decoding. You instantly understand car fault codes.
2. Most common causes
AI identifies why the issue occurs.
Typical causes like:
- Faulty modules
- Damaged wiring
- Loose or corroded connectors
- Sensor failures (e.g., transmission range sensor)
This helps you focus on the real issue.
3. Drivability status
You immediately know if your car is safe to drive:
- Safe to drive
- Limited functionality
- Potential risk
This is critical for issues involving the engine, transmission, or emissions control systems.
4. Urgency of the fix
Not every fault code requires immediate action.
AI clearly tells you:
- Not urgent — monitor
- Moderate — fix soon
- Urgent — fix immediately
You avoid unnecessary stress and make informed decisions.
5. Diagnosis and Fix
You get structured diagnostics troubleshooting guidance:
- What technicians will inspect
- Which components are involved
- Typical repair procedures
This connects scan tool data to real-world repairs.
6. Estimated repair cost
You see a realistic cost range before visiting a mechanic.
Examples:
- Wiring repair: $100–$300
- Module replacement: $300–$800
This helps you plan ahead and avoid unexpected expenses.
