MAGNETIC SWITCH RETURN TEST(1) Disconnect field coil wire from M-terminal of magnetic
switch.(2) Connect a 12 V battery between M-terminal and body.
Caution
This test must be performed quickly (in less than 10
seconds) to prevent coil from burning.(3) Pull pinion out and release. If pinion quickly returns to
its original position, everything is in order. If it doesn’t,
replace magnetic switch.
Caution
When pulling out the pinion, be careful not to have
your finger pinched.
STARTER RELAY(1) Remove the starter relay from the relay box.
(2)Connect battery to terminal 2 and check continuity between
terminals with terminal 4 grounded.

OPERATIONl
Turn ignition switch to .“ON”position, and batteryvoltage will be applied to primary winding of
ignition coil.l
When crankshaft position sensor and camshaft
position sensor signal is input to engine control
module, engine control module makes ON-OFF
control of power transistors one by one.l When power transistor is turned on, current
flows from ignition coil (primary winding) to
ground through power transistor.l When power transistor A is turned from ON
to OFF, the spark plugs of No. 1 and No. 4
cylinders spark. Turning of power transistor B
from ON to OFF will produce sparking in spark
plugs of No. 2 and No. 5 cylinders. Furthermore,
when power transistor C is turned from ON toOFF, sparking is produced in spark plugs of
No. 3 and No. 6 cylinders.
TROUBLESHOOTING HINTS1. Engine cranks, but does not start.
(1) Spark is insufficient or does not occur at
all (on spark plug).l Check ignition coil.
l Check camshaft position sensor and
crankshaft position sensorl Check power transistor.
l Check spark plugs.
l Check spark plug cable.
(2) Spark is good.
l Check ignition timing.
2. Engine idles roughly or stalls.
l Check spark plugs.
l Check ignition timing.
l Check ignition coil.
l Check spark plug cable.
3. Poor acceleration
l Check ignition timing.
l Check spark plug cable.
l Check ignition coil.

WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING!
(1) Improper service or maintenance of any component of the
SRS, or any SRS-related component, can lead to personal
injury or death to service personnel (from inadvertent firing of the air bag) or to the driver and passenger (from render-
ing the SRS inoperative).
(2) Service or maintenance of any SRS component or
SRS-related component must be performed only at an authorized
MITSUBISHI dealer.
(3)MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B
TSupplemental Re-
straint System (SRS) and GROUP 00 -Maintenance Service before beginning any service or maintenance of any com-
ponent of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: impact sensors, SRS diagnosis unit, SRS warning light, air bag module, clock spring
and interconnecting wiring. Other SRS-related components (that may
h,a”” to be removed/installed in connection with SRS serviceor maintenance) are indicated in the table of contents by an asterisk ( ).

BAlTERY VISUAL CHECK (1)
The battery contains a visual test indicator which gives blue
signal when an adequate charge level exists, and white signal
when charging is required.
BAlTERY VISUAL CHECK (2)
Make sure ignition switch is in Off position and all battery
feed accessories are Off.
1.Disconnect ground cable from battery before disconnecting
(+) cable.
2. Remove battery from vehicle.
CautionCare should be taken in the event battery case is
cracked or leaking to protect hands from the electro-
lyte. A suitable pair of rubber gloves (not the house-hold type) should be worn when removing battery
by hand.
3.Inspect battery carrier for damage caused by loss of acid
from battery. If acid damage is present, it will be necessaryto clean area with a solution of clean warm water and
baking soda. Scrub area with a stiff bristle brush and wipe
off with a cloth moistened with ammonia or baking soda
in water.
