P1A1C GMC Code - Hybrid Battery 6 Temperature Sensor Performance
Quick Answer
The Battery Energy Control Module (BECM) monitors the hybrid battery pack temperature sensors to detect the failure of any sensor during a rationality check. Common causes include Faulty Battery Energy Control Module (BECM), Battery Energy Control Module (BECM) harness is open or shorted, Battery Energy Control Module (BECM) 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.
