Communications Network
The terminating resistors of the HS-CAN multimedia
system are located in the IPC (instrument panel cluster)
and in the ACM (audio front control module).
The HS-CAN multimedia bus signals can be picked off
via pins 1 and 8
E224838
Two modules are designed as gateways:
• The BCM between the HS-CAN and MS-CAN
• The IPC between the MS-CAN and HS-CAN
multimedia
Module acronyms:
• ACM (audio front control module)
• DSP (audio digital signal processing module)
• EFP (electronic (finisher panel)
• APIM (SYNC module)
• IPC (instrument panel cluster)
• PDM (passenger door module)
• DDM (driver door module)
• HVAC (heating, ventilation and air conditioning)

Lesson 4 – Electrical
The RCM (restraints control module) is connected to
the CAN module via a private HS-ABS (anti-lock brake
system) bus. Two separate termination resistors are
installed here.
The MS CAN bus terminating resistors are located in
the IPC and the BCM. The total resistance can be
measured at the DLC between pins 3 and 11 and should
be 60 ohms.
