IGNITION SYSTEM
GENERAL INFORMATIONM1163000100294
This system is equipped with two ignition coils (A and
B) with built-in power transistors for the No. 1 and
No. 4 cylinders and the No. 2 and No. 3 cylinders
respectively.
Interruption of the primary current flowing in the pri-
mary side of ignition coil A generates a high voltage
in the secondary side of ignition coil A. The high volt
-
age thus generated is applied to the spark plugs of
No. 1 and No. 4 cylinders to generate sparks. At the
time that the sparks are generated at both spark
plugs, if one cylinder is at the compression stroke,
the other cylinder is at the exhaust stroke, so that
ignition of the compressed air/fuel mixture occurs
only for the cylinder which is at the compression
stroke.
In the same way, when the primary current flowing in
ignition coil B is interrupted, the high voltage thus
generated is applied to the spark plugs of No. 2 and
No. 3 cylinders.
The engine-ECU or engine-A/T-ECU
turns the two power transistors inside the ignition
coils alternately on and off. This causes the primary
currents in the ignition coils to be alternately inter
-
rupted and allowed to flow to fire the cylinders in the
order 1-3-4-2.
The engine-ECU or engine-A/T-ECU
determines which ignition coil should be controlled
by means of the signals from the camshaft position
sensor which is incorporated in the camshaft and
from the crank angle sensor which is incorporated in
the crankshaft. It also detects the crankshaft position
in order to provide ignition at the most appropriate
timing in response to the engine operation condi
-
tions. It also detects the crankshaft position in order
to provide ignition at the most appropriate timing in
response to the engine operation conditions.
When the engine is cold or operated at high alti-
tudes, the ignition timing is slightly advanced to pro-
vide optimum performance.
When the automatic transmission shifts gears, the
ignition timing is also retarded in order to reduce out
-
put torque, thereby alleviating shifting shocks.

M1163004300342
CAUTION
When pulling off the spark plug cable from the
plug always hold the cable cap, not the cable.
1. Remove the spark plug cables.
2. Remove the spark plugs.
3. Check for burned out electrode or damaged insulator. Check for even burning.
4. Remove carbon deposits with wire brush or plug cleaner. Remove sand from plug screw with
compressed air.

5. Use a plug gap gauge to check that the plug gap is within the standard value range.
Standard value: 1.0 − 1.1 mm
If the plug gap is not within the standard value
range, adjust by bending the earth electrode.
CAUTION
Be careful not to allow foreign matter in cylin-
ders.
6. Clean the engine plug holes.
7. Install the spark plugs.

GENERAL INFORMATION
FRONT AXLE26-2
GENERAL INFORMATION
M1261000100648
The front axle consists of front hubs, knuckles, wheel
bearings and driveshafts, and has the following fea
-
tures:
•The wheel bearing is a double-row angular con-
tact ball bearing which incorporates the oil seals
and is highly resistant to thrust loads.
•The driveshaft incorporates BJ-TJ type constant
velocity joints with high transmission efficiency for
low vibration and noise.
•The dynamic damper has been mounted on the
driveshaft to reduce differential gear noise.
•ABS rotor for detecting the wheel speed is
press-fitted to the BJ.
NOTE: .
•TJ: Tripod Joint
•BJ: Birfield Joint
