Global Customer Symptom Code (GCSC) Chart
WARNING: This page is about a different car, the 2021 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
In most circumstances the PCM will set a DTC to help guide with diagnostics. Refer to the DTC Chart before using the Symptom Chart. The Condition column lists the vehicle condition. The Action column refers to a pinpoint test. Each pinpoint test lists the possible symptoms and the components that can cause each symptom. The components are listed in order of disassembly.
NOTE:
This procedure is written to diagnose multiple vehicle applications. It includes information for shift by cable, shift by wire, and auto start-stop applications. Some components listed may not apply to every vehicle.
