P1A62 Saturn Code - Starter/Generator Control Module Torque Delivered Performance
Quick Answer
The Starter/Generator Control Module (SGCM) monitors the internal torque value and compares it to the Motor Generator Unit (MGU) delivered torque value. Common causes include Faulty Motor Generator Unit (MGU), Motor Generator Unit (MGU) harness is open or shorted, Motor Generator Unit (MGU) 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.
