P1ABA Buick Code - Starter/Generator Field Coil Current Sensor Circuit High Voltage
Quick Answer
The Starter/Generator Control Module (SGCM) monitors the Motor Generator Unit (MGU) field coil circuit to see if the field coil current is within tolerance. 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.
