FUEL PUMP RELAY CONTROL
MULTIPORT FUEL SYSTEM (MFI)13A-46
FUEL PUMP RELAY CONTROLM2132006500208
When current flows through the fuel pump relay, the
relay turns ON and the fuel pump is driven. The fuel
pump relay is built into the ETACS-ECU. When the
ignition switch-ST signal is input, ECM turns ON the
power transistor for control of the fuel pump relay. As a result, power is supplied to the fuel pump. Also, if
engine speed falls below a set value, the fuel pump
relay is turned OFF. Thus, it deals with sudden stop
-
pages such as engine stalling etc. by stopping the
pump.

A/C COMPRESSOR RELAY CONTROL
MULTIPORT FUEL SYSTEM (MFI)13A-50
A/C COMPRESSOR RELAY CONTROLM2132034500120
The ECM turns on the power transistor when the A/C
switch ON signal is input by the A/C-ECU through
the CAN. This allows the A/C compressor relay to be
ON and to be operated. During the high load opera
-
tion, such as the acceleration with the fully opened
accelerator, the ECM secures the acceleration capa
-
bility by turning off the A/C compressor relay for the
specified period to produce no load on the A/C com
-
pressor.

GENERAL
BASIC BRAKE SYSTEM35A-2
GENERALM2350000100956
Brake systems with higher reliability and durability
have achieved distinguished braking performance.
FEATURES
.
IMPROVEMENT OF BRAKING PERFOR-
MANCE
•A 10-inch single brake booster with the variable
boost ratio mechanism has been used to assure
maximum braking force with less pedal pressure
in case of emergency.
•In addition to the 10-inch single brake booster, a
small and long stroke-type master cylinder has
been adopted to achieve downsizing and secure
assist force.
•15-inch or 16-inch ventilated disc brakes have
been adopted for the front.
•8-inch leading trailing-type drum brake, 14-inch
or 16-inch solid disc brake has been adopted for
the rear.
.
IMPROVEMENT IN SAFETY
•The 4-wheel anti-lock brake system (4ABS) has
been installed to prevent slippage resulting from
the wheel lock and assure stable vehicle posture
and driveability.
•A rear wheel early lock-prevention proportioning
valve has been used.
•Electronic control braking force distribution sys-
tem (EBD) has been adopted to assure the maxi-
mum braking force independently of the
passenger's position in the vehicle. with ABS>
•X-type piping of brake lines have been adopted
for the front and rear wheels.
•Audible wear indicators are used on the front and
rear brake pads to warn the driver of wear limit.
.
SERVICE QUALITY IMPROVEMENTS
•Diagnostic function has been adopted to ABS for
easier inspection.
•Brake fluid reservoir, master cylinder, and brake
booster have been integrated for downsizing and
better serviceability.
