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 ( ).

A-6There is noise when starting the engine.
Noise type
Sounds are in pa-
rentheses ( ).
AM, FM:
Ignition noise
(Popping, Snap-
ping,Cracking,
Buzzing)
Otherelectrical
components
Static electricity
(Cracking, Crin-
kling)
Conditions
0Increasing the engine speedcausing the popping sound tospeed up, and volume de-creases.0Disappears when the ignitionswitch is turned to ACC.
-
lDisappears when the vehicle is
completely stopped.Occurs when parts or wir-
Severe when the clutch is en-ing move for some reasonlgaged.and contact metal parts of
the body.
lVarious noises are produced de-pending on the body part of thevehicle.
Due to detachment from
the body of the front hood,
bumpers, exhaust pipe
and muffler, suspension,
etc.
Causel
Mainly due to the
spark plugs.l Due to the enginenoise.
Noise may appear as
electrical components be-
come older.

cable2, 3
Repair or replace electricalcomponents.
Return parts or wiring to
their proper position.
Caution
1.Connecting a high tension cable to the noise
filter may destroy the noise filter and shouldnever be done.
2.Check that there is no external noise. Since
failure to do this may result in misdiagnosis
due to inability to identify the noise source,
this operation must be performed.3. Noise prevention should be performed by
suppressing strong sources of noise step
by step.
NOTE
1. Condenser
The condenser does not pass D.C. current, butas the number of waves increases when it
passes A.C. current, impedance (resistanceagainst A.C.) decreases, and current flow is
facilitated. A noise suppressing condenser
which takes advantage of this property is in-
serted between the power line for the noise
source and the ground. This suppresses noiseby grounding the noise component (A.C. or
pulse signal) to the body of the vehicle.
2. Coil
The coil passes D.C. current, but impedance
rises as the number of waves increases relativeto the A.C. current. A noise suppressing coil
which takes advantage of this property is in-
serted into the power line for the noise source,
and works by preventing the noise componentfrom flowing or radiating out of the line.

Ground parts by bonding.
Cases where the problem
is not eliminated by a single
response to one area are
common, due to several
bodypartsbeing
imperfectly grounded.
