Bulletin Summary
Some 2017-2021 Ford GT vehicles may exhibit diagnostic trouble code (DTC) P166B present in the gear shift module (GSM) after an on-demand self test is performed. This is likely due to the driver door not being fully closed and locked during the on-demand self-test. A false P166B DTC can set if the driver door is not fully closed or if it is unlocked during the self-test. If P166B is still present with the driver door fully closed and locked during the on-demand self-test, continue with normal diagnostics in Workshop Manual (WSM), Section 307-05.
About Technical Service Bulletins
A Technical Service Bulletin (TSB) is a document issued by a vehicle manufacturer to its dealers, describing a known issue with a specific vehicle or set of vehicles and the recommended procedure to fix it. Unlike recalls, TSBs are not mandatory and are typically only performed if an owner reports the related issue. However, TSBs can be an indicator of common problems with a vehicle.
