Prelude Type-SH L4-2157cc 2.2L DOHC H22A4 (VTEC) 16V (1998)
General Module: Description and Operation
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.
