WARNINGS REGARDING SERVICING OF SUPPLEMENTAL RESTRAINT SYSTEM (SRS) EQUIPPED VEHICLES
WARNING
•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
paassenger (from rendering the SRS inoperative).
•Service or maintenance of any SRS component or SRS-related component must be performed only at an
authorized MITSUBISHI dealer.
•MITSUBISHI dealer personnel must thoroughly review this manual, and especially its GROUP 52B - Supplemental
Restraint System (SRS) before beginning any service or maintenance of any component of the SRS or any
SRS-related component.
NOTE
The SRS includes the following components: SRS air bag control unit, SRS warning light, front impact sensors, air bag module,
clock spring, and interconnecting wiring. Other SRS-related components (that may have to be removed/installed in connection
with SRS service or maintenance) are indicated in the table of contents by an asterisk (*).

FLUID LEVEL AND SPECIFIC GRAVITY
CHECK
M1541001000438
CAUTION
•If the battery fluid is below the LOWER
LEVEL, the battery could explode in using.
•If the battery fluid is over the UPPER LEVEL,
leakage could result.
1. Inspect whether or not the battery fluid is between
the UPPER LEVEL and LOWER LEVEL marks.
2. Use a hydrometer and thermometer to check the
specific gravity of the battery fluid.
Standard value: 1.220 − 1.290 (20°C)
3. The specific gravity of the battery fluid varies with
the temperature, so use the following formula to
calculate the specific gravity for 20°C. Use the
calculated value to determine whether or not the
specific gravity is satisfactory.
D20 = (t − 20) X 0.0007 + Dt
D20: Specific gravity of the battery fluid
calculated for 20°CDt: Actually measured specific gravity
t: Actually measured temperature
CHARGINGM1541001100509
CAUTION
•The battery plus should be removed during
charging.
•The battery electrolyte level may rise and
overflow from the battery during charging.
•Explosions may occur if the battery is
brought close to naked flames during
charging.
•Be careful to avoid tasks that might produce
sparks or other danger while the battery is
charging.
•After charging is complete, replace the
battery plus, pour water over the battery to
rinse away any sulphuric acid, and let the
battery stand to dry.
•Charge the battery in a well-ventilated
location.
•Do not let the battery electrolyte temperature
rise above approximately 45°C (approximately
55°C during rapid charging).
1. Remove the battery from the vehicle.
2. The normal charging current is a value in
amperes which is 1/10th of the battery capacity. If
the battery needs to be charged rapidly because
of reasons such as time limitations, the maximum
charging current for rapid charging is the battery
capacity expressed as an ampere value.
3. Determine when charging is finished.
•When the specific gravity of the battery
electrolyte is constantly within 1.250 − 1.290 for a
continuous period of one hour or more.•When the voltage per cell during charging is 2.5 −
2.8 V constantly for a continuous period of one
hour or more. Items Specification

NOTE:
Prior to the wiring harness inspection, check key
reminder switch connector C-202, intermediate
connector C-13
connector C-202-1 (terminal 3) and engine-ECU
connector C-127 (terminal 51)
engine-A/T-ECU connector C-128 (terminal 111)
in good condition?
YES :
Go to Step 10.
NO : Repair or replace the damaged
component(s). Confirm that MUT-II/III
communicates normally.
STEP 10. Replace the immobilizer-ECU or
engine-ECU
Replace the immobilizer-ECU.
Q: Did the communication with MUT-II/III become
possible after replacing the immobilizer-ECU?
YES :
Register the password (secret code) and
encrypted code P.54A-20. Confirm that
MUT-II/III communicates normally
NO : Go to Step 11.
STEP 11. Recheck for malfunction.
Q: Is a malfunction eliminated?
YES :
The procedure is complete. If no
malfunctions are found in all steps, an
intermittent malfunction is suspected (Refer
to GROUP 00, How to Use
Troubleshooting/Inspection Service Points −
How to Cope with Intermittent Malfunction
P.00-5).

INSPECTION PROCEDURE 2: The Ignition Key cannot be Registered.
TECHNICAL DESCRIPTION (COMMENT)
The ignition key transponder or the immobilizer-ECU
is suspected to be defective.
TROUBLESHOOTING HINTS
•Malfunction of the ignition key
•Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. MUT-II/III diagnosis code.
Q: Does diagnosis code No.11 reset?
YES :
Refer to P.54A-9.
NO : Replace the ignition key that cannot be
registered. Then re-register the encrypted
code. (Refer to P.54A-20). Verify that the
ignition key can be registered, then Go to
Step 2.
STEP 2. Retest the system.
Q: Does registered ignition key function properly?
YES :
The procedure is complete. (If no
malfunctions are found in all steps, an
intermittent malfunction is suspected. Refer
to GROUP 00, How to Use
Troubleshooting/Inspection Service Points −
How to Cope with Intermittent Malfunction
P.00-5).
NO : Replace the immobilizer-ECU.
INSPECTION PROCEDURE 3: Engine does not Start (Cranking but no Initial Combustion).
TECHNICAL DESCRIPTION (COMMENT)
If the fuel injectors are not operating, there might be
a problem with the MPI system in addition to a
malfunction of the immobilizer system. It is normal for
this to occur if an attempt is made to start the engine
using a key that has not been properly registered.
TROUBLESHOOTING HINTS
•Malfunction of MPI system
•Malfunction of immobilizer-ECU
DIAGNOSIS PROCEDURE
STEP 1. Check the system voltage.
Measure the system voltage during cranking.
Q: Is the voltage 8 volts or more?
YES :
Go to Step 2.
NO : Check the battery. Refer to P.54A-4. The
engine should start.
STEP 2. Check the immobilizer system diagnosis
code and MPI system diagnosis code.
Q: Which diagnosis code resets, the immobilizer
system diagnosis code or the MPI system
diagnosis code?
Immobilizer system diagnosis code is set :
Refer
to P.54A-9.
MPI system diagnosis code is set : Refer to
GROUP 13A, Diagnosis P.13A-15, GROUP
13B, Diagnosis P.13B-15.
No diagnosis code is set : Go to Step 3.
STEP 3. Check the starting system.
Q: Does the engine start?
YES :
Go to Step 4.
NO : Refer to GROUP 13A, Diagnosis −
Symptom Chart P.13A-215, GROUP 13B,
Diagnosis − Symptom Chart P.13B-189. If
the malfunction is not resolved, replace the
immobilizer-ECU. Then register the
password (secret code) and encrypted
code. (Refer to P.54A-20.) The engine
should start.
