843. Output Level
ECU output level is designed to send control signal to the actuators of the electronic control system based on
the orders of the microprocessor in the micro-controller. The microprocessor control the output level by
controlling the occurrence position of the pulse, its length and duty ratio.
(1) Injection output level
The microprocessor controls the pulse length of the injection output level by making sure whether to
trigger to circuit or not in the injection output level.
(2) Ignition input level
The ignition output level is designed to amplify the ignition signal from the microprocessor into the primary
current of the ignition coil.
(3) Electric fuel pump output level
ECU microcontroller control the pump relay through electric fuel pump output level, and then control the
on and off of the electric fuel pump based on the current operating conditions.
(4) Other output levels
Control the output levels of the idle control valve, carbon canister solenoid valve, malfunction indicator
lamp. MR479Q, MR479QA, MR481QA engine idle control are closed loop control system, their injection
and ignition control are also closed loop control system.

102(7) Install front wheel, wheel nut torque: 95~115N.m
(8) Make sure that the propeller shafts for 1.3L engine and 1.5L engine are not interchanged
at the time of replacement
(9) Check the ABS sensor signal, check and adjust the front wheel alignment if necessary.

103Chapter 5 Front Suspension SystemSection 1 Front Suspension SystemDescription on front suspension structure
This model uses strut swing arm independent suspension with stabilizer bar.
The shock absorber upper end is flexibly connected to the body through the shock absorber mounting seat,
the lower end is rigidly connected to the steering knuckle. The coil spring encloses the shock absorber (coil
spring geometrical axial line does not coincide with that of the shock absorber piston rod), and is supported
between the upper and lower spring seats.
Both ends of the stabilizer bar are connected to the shock absorber through the strut bar ball pin and the
intermediate part is supported on the lower front body by the rubber bushing and support frame.
The front cushion sleeves the shock absorber piston rod head to restrict the wheel jump limit position and
plays the role of buffer.
The thrust ball bearing, installed between the spring upper seat and the shock absorber mount, is used for the
relative rotation upon steering of the shock absorber rigidly connected to the steering knuckle to the shock
absorber mount flexibly connected to the body.
"L" type lower swing arm is secured to the lower engine compartment with the press plate through elastic
rubber bushing and hinge, and its outer end is connected to the steering knuckle through the ball stud pin
which is attached to the lower swing arm by 3 high intension bolts. The ball stud pin can be removed and
replaced when it is worn.
The ball seat material is saturated polyester containing oil, featured in comparatively high intensity and
wearability and good self-lubrication performance. Proper amount of grease has been added during the
assembly and there is no need for additional filling during the normal operation.

1155. Install the front stabilizer bar
Install stabilizer bar, 2 rubber bushings, the front stabilizer bar clamp and 4 bolts.
Torque: 50~60N.m
Notice:
(1) Align the inner rubber bushing with the mark on the stabilizer bar.
(2) The 4 bolts connecting the stabilizer bar clamp and front stabilizer bar support
frame welding assembly differ in length. The two short ones are close
6. Install stabilizer bar link rod assembly
(1) Attach the stabilizer bar link rod to the stabilizer bar with nuts.
Torque: 40~50 N.m
(2) Attach the stabilizer bar link rod to the front shock absorber bracket with nuts.
Torque: 40~50 N.mto engine.

134On-vehicle inspection1. check the drive belt
Observe the drive belt for excessive wear and cordline wear. Replace the drive belt if necessary.
Hint: Cracks on the rib side of a belt are considered acceptable. If missing chunks from the
ribs are found on the drive belt, it should be replaced.
2. Bleed the power steering system
(1) Check the fluid level
(2) Jack up the front of the vehicle and make sure it is safe
(3) Rotate the steering wheel
a. With the engine off, turn the steering wheel from LH limit position to RH limit position several
times
(4) Release the jack and lower the vehicle
(5) Start the engine, run the engine at idle for a few minutes
(6) Turn the steering wheel to left or right limit position and keep it there for 2 - 3 seconds, then turn the
steering wheel to the opposite limit position and keep it there for 2 - 3 seconds. Repeat it several
times.
(7) Shut off the engine, check for foaming or emulsification in the reservoir. If there is foaming or
emulsification, bleed power steering system repeatedly
(8) Check the fluid level and for leakage
2. Check the fluid level
(1) Park the vehicle on a level surface
(2) With the engine stopped, check the fluid level in the reservoir. Add power steering fluid AT F
DEXRON if necessary.
Hint: the fluid level should be within the range of lowest level and highest level
(3) Check for foaming or emulsification, if there is, drain the power steering systemNormalAbnormal
