Operation CHARM: Car repair manuals for everyone.

Description

The multiplex control unit is composed of three control units (located in the driver's side kick panel, passenger's side kick panel, and driver's door).
These three control units integrate the independent control units as usual and feature multiplex communication lines. The system reduces the number of control units and wire harness bulk, and improves the quality of electrical functions by means of the integrated circuits. This system has a built-in self-diagnosis function.
