Not every vehicle fault can be properly investigated with a basic diagnostic scan.
Modern vehicles contain increasingly complex electronic systems, with multiple control modules communicating across the vehicle.
When a fault is difficult, intermittent or manufacturer-specific, more advanced diagnostic access may be required.
What Can Advanced Diagnostics Investigate?
Depending on the vehicle, advanced diagnostics can provide access to a wider range of systems and information.
This can help investigate:
- Complex engine faults
- Electrical problems
- Communication faults
- ECU issues
- ABS faults
- Airbag and SRS faults
- DPF problems
- AdBlue faults
- Transmission faults
- Driver assistance systems
- Camera systems
- Parking systems
- Body control systems
- Intermittent electronic faults
When Is Dealer-Level Diagnostics Worth Considering?
Advanced diagnostics can be particularly useful if:
- A basic scan hasn’t identified the problem
- A fault keeps returning
- Multiple warning lights have appeared
- The vehicle has an intermittent electrical issue
- A replacement module isn’t communicating correctly
- You’ve installed a retrofit
- A manufacturer-specific fault has been identified
- You need access to additional vehicle systems
More Than Just Reading Fault Codes
A diagnostic trouble code doesn’t necessarily mean that the component named in the code is faulty.
Further investigation may be needed to establish the underlying cause.
Advanced diagnostics can allow us to access additional information, live data and vehicle systems where supported.
This provides a more detailed picture of what’s happening with the vehicle.
