The APIM becomes inoperative at random times for ~8 hours. When this happens the entire dashboard gs black and you cant tell your speed, turn signals, rpm, engine temp, oil pressure, etc. You are driving with no indicators and have no idea what your speed is or any other critical indication. APIM stands for Accessory Protocol Interface Module, also known as the Ford SYNC computer. It’s a key component of the SYNC system in Ford vehicles. Ford has equipped vehicles with the APIM since its inception, but there have been complaints and recalls related to it.
