High Speed Controller Area Network (HS-CAN) and Medium Speed Controller Area Network (MS-CAN)
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
The high speed controller area network (HS-CAN) circuits that pass through the passenger seat 12 pin electrical connector are part of the main HS-CAN LOOP. If the front passenger seat-to-floor 12 pin electrical connector is disconnected, a NO START condition will result.
NOTE:
The medium speed controller area network (MS-CAN) circuits that pass through the driver and passenger seat harnesses are part of the main MS-CAN LOOP. If the driver seat-to-floor 57 pin electrical connector is disconnected when equipped with memory seats, various MS-CAN modules will not be able to communicate. If the front passenger seat-to-floor 30 pin electrical connector is disconnected when equipped with climate control seats, various MS-CAN modules will not be able to communicate.
This vehicle utilizes 2 communication systems called HS-CAN and MS-CAN. The memory seat and climate controlled seat communicate over the MS-CAN. When diagnosing the memory seat or climate controlled seat, use a Vehicle Communication Module (VCM) and Integrated Diagnostic System (IDS) software with appropriate hardware, or equivalent scan tool with the latest software update with the capability of communicating over the MS-CAN bus.
