P1A80 GMC Code - Starter/Generator Control Module Coolant Level Sensor 1 High Voltage
Quick Answer
The Starter/Generator Control Module (SGCM) electronics are immersed in an internal fluid to distribute the heat of the electronics evenly through the SGCM, this electronics internal fluid is not the coolant that is circulated through the SGCM cooling system. Common causes include Faulty Starter/Generator Control Module (SGCM), Starter/Generator Control Module (SGCM) harness is open or shorted, Starter/Generator Control Module (SGCM) circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.
