Manage wireless communication Communicates with: Key fob Body Control Module (BCM) Engine Control Module (ECM) Security system 5. Enable convenience features It allows modern comfort features such as: Keyless entry Remote start Push-to-start ignition Automatic door-lock/unlock based on fob proximity Signs of a Bad Wireless Ignition Node Module 5026878AD: 1.
