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 GTW_w038 mean?
The gateway detected a version mismatch with the restraints control module (RCM), which manages the airbags and seatbelt pretensioners. Per Tesla the RCM may not function properly, so it is a safety-relevant alert often caused by a software mismatch or a corrupted gateway SD card.
Is GTW_w038 safe to ignore?
No. It involves the restraints (airbag) system, which may not work correctly until the mismatch is fixed. Have Tesla service address it promptly.

Step-by-Step Diagnostic Procedure
Because this concerns the restraints (airbag / SRS) system, treat it seriously -- a mismatched RCM may not deploy correctly in a crash.
This is typically resolved with a Tesla software/configuration fix or gateway SD card service, not a DIY repair.
Have Tesla service correct the version mismatch promptly; do not ignore an SRS-related alert.
