I am a DIYer but I am savy enough to know to follow instructions when using a new electronic tool. However, It seems I did something wrong or there is something wrong with my unit. I have a CRP 123x OB2 scanner reader. When I tried using it on a 2015 Subaru then a 2013 Chevy Equinox it would not read the VIN so I tried firmware fix and it gave me a (code:1) failure. I am at a loss on how to get this started or did I buy a dude.
Hi Dean,
Sorry to hear you’re having trouble with your CRP 123x OBD2 scanner—it’s definitely irritating when a tool doesn’t work as expected. Since it’s not reading the VIN on both your 2015 Subaru and 2013 Chevy Equinox, try ensuring the scanner is securely connected and the ignition is in the “On” position. The (code:1) failure during the firmware update might indicate an issue with the update process, so re-downloading the firmware from the official site and trying again could help. If possible, resetting the scanner to factory settings might resolve any glitches. If none of these steps work, the unit could be defective, and reaching out to the manufacturer or retailer for support or a replacement might be the best next step.
Hope you get it sorted out soon!
