Not sure if this is anything to be concerned about... But I finally got my Z back this last weekend. When I got home, I decided to plugin my code reader to see if there were any codes stored in the ECU. CEL was not on so as expected, no codes for the engine. ABS however had one code stored (86-1). The only thing I can think of was that a few months ago, I received an ABS and VSA system alert in the i-mid when I plugged my tuner in to the car. No warning lights currently and the car drives fine. ABS and VSA seem to work properly. Does anyone know if ABS codes clear on their own or do they need to be cleared manually?
