The GCA Performance OBD Module is designed to plug directly into your vehicle's OBD port to detect and mange diagnostic error codes. The module identifies specific fault codes and digitally suppresses them, automatically correcting and clearing the codes during operation.

It primarily addresses the main codes (including but not limited to): P0420, P0430, P03270, P03271, P0226E, P0226D

No tuning software or vehicle programming is required. The device operates electronically through the OBD interface and does not modify, replace, or alter any vehicle hardware components.
