Why this matters during an appraisal
When evaluating a vehicle, you want to know if any issues may have been hidden by recently clearing trouble codes.
Codes can be cleared:
Unintentionally – dead battery, battery replacement, or recent service
Intentionally – using a scan tool or disconnecting the battery
Either way, if codes were just cleared, the vehicle hasn’t had enough time to confirm whether underlying issues are truly resolved.
How BlueDriver helps
BlueDriver removes the guesswork with a simple message:
“Check Engine Light is off but has been cleared recently.”
This gives you a clear signal that:
The Check Engine Light is currently off
But the vehicle hasn’t fully “proven” that everything is OK yet
Why not just use miles driven?
Some tools only show distance since codes were cleared (e.g., 5 miles, 10 miles, etc.).
The challenge:
There’s no clear standard for what counts as “long enough”
Appraisers are left deciding:
Is 5 miles, 20 miles, etc. enough?
Distance alone doesn’t tell the full story.
What BlueDriver does differently
BlueDriver checks the same built-in vehicle systems (monitors) that manufacturers use.
These monitors look at multiple factors, including:
Time since codes were cleared
Number of drive cycles (how many times the car has been driven)
Engine warmups
Real driving conditions (like idling, highway speeds, braking)
What the result means for you
If you see “Recently Cleared”
The vehicle has not completed its internal checks yet
It’s too soon to confirm that no issues exist
You should treat the vehicle with additional caution during appraisal
If you do NOT see the warning
The vehicle has completed its checks
The Check Engine Light is still off
You can be more confident that no active issues are being masked
Bottom line for appraisals
“Recently Cleared” = Not enough data yet → proceed with caution
No warning = Vehicle has passed its internal checks → higher confidence
