P16D6 Code - IMA-CAN Malfunction Internal Malfunction
Quick Answer
The Integrated Motor Assist-Controller Area Network (IMA-CAN) uses two signal lines, IMACANH and IMACANL, and it receives and transmits multiple signals simultaneously to/from multiple control modules. Common causes include Controller Integrated Motor Assist-Controller Area Network (IMA-CAN) Communication, Faulty Powertrain Control Module (PCM), Powertrain Control Module (PCM) harness is open or shorted. 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.
