C1AAD Code - Vehicle Information Initialization Incomplete
Quick Answer
When the Forward Recognition Camera is replaced with a new one, the new forward recognition camera attempts to store the vehicle information received from the Engine Control Module (ECM). Common causes include Faulty Forward Recognition Camera, Forward Recognition Camera harness is open or shorted, Forward Recognition Camera 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.
