engaged, and then remove the passenger’s air bag module.
Caution
1. When the passenger’s air bag module is removed,
do not damage the engagement of the pawls.
2. The removed passenger’s air bag module should be
stored in a clean, dry place with facing the deployment
surface facing up.
INSTALLATION SERVICE POINTS
"AAPRE-INSTALLATION INSPECTION
1. Pre-installation inspection is carried out even if installing
a new air bag module or clock spring. (Refer to P.52B-59.)
Caution
A used air bag module must be discarded after
deoloyment according to the specified procedure.
(Refer to P.52B-64.)
2. Connect the negative ( - ) terminal of the battery.
3. Connect the MUT-II to the diagnosis connector (16 pin).
Caution
Connection and disconnection of the MUT-IImust
be carried out after turning the ignition switch to the
LOCK (OFF) position.
4. Turn the ignition switch to ON.
5. Check that there is no abnormality except for open circuit
in the air bag module after reading diagnostic codes.
6. Turn the ignition switch to LOCK (OFF) position.
7. Release the negative ( - ) terminal cable of the battery
and wrap a tape around it for insulation.
Caution
Wait for at least 60 seconds after disconnecting the
negative ( - ) battery cable before starting any
operation. (Refer to P.52B-3.)
"BACLOCK SPRING INSTALLATION
1. Check that the steering wheel is positioned in the forward
direction.
2. Install the column switch to the clock spring after centering
of the clock spring is carried out as follows.
Centering of the clock spring
After turning the clock spring clockwise fully, turning approximately
3 rounds in the opposite direction, and align mating marks.
Caution
If centering of the clock spring is not properly done, the
SRS air bag system does not function normally due to
possible malfunctions that the steering wheel may not turn
in the way or cables in the clock spring may be torn.

INSPECTION
DRIVER’S AND PASSENGER’S AIR BAG MODULE
INSPECTION
If any malfunction is found in the following inspection, replace
the air bag module(s) with new one(s).
Discard the old one(s) after deployment as specified in the
service procedure. (Refer to P.52B-64.)
Caution
Never measure circuit resistance in the air bag modules
(squib) even with the specified tester. Measuring the
circuit resistance with a tester causes accidental air bag
deployment due to current that flows or static, resulting in
serious personal injury.
1. Check the cover for dents, cracks or deformation.
2. Check the connectors for damage, terminals for
deformation, and harness for binds.
3. Check the air bag inflator cases for dents, cracks or
deformation.
4. With air bag module installed
Caution
If dents, cracks, deformation, or rust are present in
the air bag module(s), replace with new one(s).
Discard the old one(s) as specified in the service
procedure. (Refer to P.52B-64.)
CLOCK SPRING CHECK
If any malfunction is found in the following inspections, replace
the clock spring with a new one.

1. Check the connectors and protective tubes for damage,
and terminals for deformation.
2. Visually check the case for damage.
3. Refer to that the clock spring has continuity between
connector No.2 and terminal No.4 of connector No.1.Inflator

Inspections.)
Caution
If the seat belt with pre-tensioner is discarded, discard
it after operating the seat belt pre-tensioner according
to the specified procedure. (Refer to P.52B-64.)
2. Connect the negative ( - ) terminal of the battery.
3. Connect the MUT-II to the diagnosis connector (16 pin).
Caution
Connection and disconnection of the MUT-II must be
carried out after turning the ignition switch to the
LOCK (OFF) position.
4. Turn the ignition switch to ON position.
5. Check that there is no abnormality except for open circuit
in the seat belt pre-tensioner after reading diagnostic
codes.
6. Turn the ignition key to LOCK (OFF) position.
7. Release the negative ( - ) terminal cable of the battery
and wrap a tape around it for insulation.
Caution
Wait for at least 60 seconds after disconnecting the
negative ( - ) battery cable before starting any
operation. (Refer to P.52B-3.)
"BAPOST-INSTALLATION INSPECTION
1. Turn the ignition switch to the ON position.
2. Check that the SRS warning lamp illuminates for 6 to
8 seconds and goes out.
3. Carry out troubleshooting if the lamp does not go out.

Specific gravity of the battery fluid1.220 - 1.290 [20_C]
ON-VEHICLE SERVICE
FLUID LEVEL AND SPECIFIC GRAVITY CHECK
1. Inspect whether or not the battery fluid is between the
UPPER LEVEL and LOWER LEVEL marks.
Caution
(1) If the battery fluid is below the LOWER LEVEL,
the battery could explode in using.
(2) If the battery fluid is over the UPPER LEVEL,
leakage could result.
2. Use a hydrometer and thermometer to check the specific
gravity of the battery fluid.
Standard value: 1.220 - 1.290 [20_C]
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)×0.0007 + Dt
D20: Specific gravity of the battery fluid calculated
for 20_C.
Dt: Actually measured specific gravity
t: Actually measured temperature
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.
Battery typeCapacity (5-hour rate)Normal charging currentRapid charging current
44B2034 A3.4 A34 A
3. Determine when charging is finished.
DWhen the specific gravity of the battery electrolyte is constantly within 1.250 - 1.290 for a
continuous period of one hour or more
DWhen the voltage per cell during charging is 2.5 - 2.8 V constantly for a continuous period
of one hour or more
