When a Check Engine Light comes on, many drivers ask: “Why do I have to pay diagnostic time?” Diagnostic labor pays for the time a skilled technician takes to identify the root cause of a problem. It is much more than just reading a code. At BA Auto Care, we use a structured three-level diagnostic system developed over decades.
Level 1 Diagnosis
- Straightforward issue
- Easy to reproduce
- Clear diagnostic pathway
- Typically, one hour of labor
Level 2 Diagnosis
- Intermittent issue
- Requires electronic testing tools
- Data collection during failure
- Up to two hours of labor
Level 3 Diagnosis
- Highly intermittent problem
- Prior repair attempts or neglect
- Advanced troubleshooting required
For efficiency, we often request authorization for Levels 1 and 2 up front. This prevents technician downtime and keeps the process moving. However, if our auto tech needs to study system theory to understand a design, that learning time is not charged to the customer.
We also use professional technical support databases to identify pattern failures specific to your make and model. Today’s modern vehicles, especially those equipped with Advanced Driver Assistance Systems (ADAS), are very complex. Diagnostic codes identify systems, not failed parts. Our 3 Level, Structured Diagnostic Process ensures:
- Efficient problem identification
- Clear communication between service advisor and technician
- Accurate repairs the first time
By following this process, we can eliminate unnecessary repairs and save you money.
