Many users want to know whether a vehicle will pass a CTC inspection prior to submitting to CARB. This provides more time than the 30-day requirement to repair a vehicle if the vehicle would fail. OBD Pre-Check™ is a separate app that works with our Mini Streamer. HEM Data’s server anticipates how CARB will analyze CTC data.

The Pre-Check™ app generates a report immediately after submitting the test. The report includes key CTC information including diagnostic trouble codes (DTCs), the number of warm-ups, miles, hours driven since codes have been cleared, and the status of each monitor. If the vehicle fails, the report states why. Click here for an example report.

The pre-check app does not require a login or an internet connection during the test. The price for the optional OBD Pre-Check™ is $395 annually.
