B1445 Code - Control Module Voltage Output Circuit
Quick Answer
The Body Control Module (BCM) controls the Retained Accessory Power Relay 1 and Retained Accessory Power Relay 2 through their control circuits by applying a voltage to the Retained Accessory Power Relay coil control circuit. Common causes include Faulty Retained Accessory Power Relay 1 or Retained Accessory Power Relay 2, Retained Accessory Power Relay harness is open or shorted, Retained Accessory Power Relay 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.
