COMMUNICATION
A/C-ECU performs the signal transmission and
reception with each ECU via CAN (Controller Area
Network)*
1. Also, with the heater control panel, it
transmits and receives signals via serial communica
-
tion.
NOTE: : For details of CAN communication, refer to
GROUP 54C
− Controller Area Network P.54C-2.

GENERAL DESCRIPTION
ENGINE MECHANICAL11A-2
GENERAL DESCRIPTIONM2112000101162
This model is equipped with a newly developed 4B11
engine. It is a 4-cylinder, double overhead camshaft
(DOHC) engine with a 2.0-L cylinder displacement.
This engine has adopted the following features:
•MIVEC (MITSUBISHI INNOVATIVE VALVE TIM-
ING ELECTRONIC CONTROL SYSTEM) for
both the intake and exhaust valves
•Cylinder block made of an aluminum alloy
•Valve train with direct-acting valve tappets
•Silent timing chain

CRANKSHAFT PULLEY
The pulley is made of cast iron.
The pulley portion has grooves for the V-ribbed belt
(with 6 crests).
The flange portion of the pulley has a timing mark
notch for checking the ignition timing.
A torsion damper has been adopted to reduce the
torsional vibration of the crankshaft, as well as to
dramatically reduce noise and vibration in the
high-speed range.
DRIVE PLATE
The drive plate is made of sheet metal.The drive plate is mounted with 7 bolts.
