ScanWrench Buyer Challenge creates a time-bound evidence record for the vehicle in front of you. It preserves what responded, what did not, and which reset clues still need an explanation.
Capture the current vehicle state before anyone clears codes, disconnects the battery, or changes the operating condition.
Incomplete readiness, recently cleared evidence, or missing history can support a follow-up question. None proves deception by itself.
Generic OBD2 does not replace brake, tire, suspension, body, restraint, high-voltage, title, flood, collision, or professional mechanical inspection.
It can expose incomplete readiness and some time-or-distance-since-clear evidence when supported, but those clues require context and do not prove why a reset occurred.
No. A scan records only the modules and data the exact setup can access. It cannot certify the whole vehicle.
A before-and-after record can be useful when safe and permitted. Preserve the initial state, then repeat the relevant scan without clearing evidence.
