A $30 car code reader can't do diesel. The HD7000 reads full-system codes and does parked DPF regen, idle/speed-limit, and service resets from the cab — on everything from a 6.7 Cummins/Power Stroke/Duramax pickup to Class-8 trucks (Detroit, Paccar, CAT, Volvo, Mack, International).

Frequently Asked Questions
What does Tesla alert UI_a014 mean?
TPMS detected a tire at least 20% below the recommended cold pressure. It does not mean a flat tire: check and refill.
Why does it clear on its own?
Tires warm up and pressure rises as you drive. Tesla still says to refill once they have cooled.
Mechanics Guide Step-by-step diagnosis
How Do You Diagnose TESLA-UI_A014?
Tesla says this does NOT indicate a flat tire.
Add air to the recommended cold pressure, even if the alert clears as the tires warm up.
The alert clears once every tire is at the recommended pressure; you may need to drive over 15 mph (25 km/h) for at least 10 minutes for new readings.
If the same tire keeps triggering it, have it inspected for a slow leak.
