If the engine is started using a booster cable when the battery is completely flat, and
the vehicle is then driven without waiting for the battery to be recharged, the engine
may misfire and it may not be possible to drive the vehicle. This is because the ABS
consumes a large amount of current when carrying out its initial checks. If this
happens, recharge the battery fully. HYDRAULIC UNIT REMOVAL AND INSTALLATION

2004 ACCESSORIES/SAFETY EQUIPMENT
Mitsubishi - Air Bag Restraint Systems
DESCRIPTION & OPERATION Supplemental Restraint System (SRS) components on vehicles with single-stage air
bag systems include single-stage driver-side and passenger-side air bag modules,
side impact air bag modules, seat belt pretensioners, front impact sensors, side
impact sensors, SRS Electronic Control Unit (SRS ECU) and an AIR BAG warning
light or SRS warning light.
SRS components on vehicles with dual-stage air bag systems include dual-stage
driver-side and passenger-side air bag modules, side impact air bag modules, seat
belt pretensioners, front impact sensors, side impact sensors, SRS Electronic
Control Unit (SRS ECU), occupant classification sensor, occupant classification
sensor ECU, seat belt switches, AIR BAG warning light or SRS warning light,
PASSENGER AIR BAG OFF warning light and a PASSENGER SEAT BELT
warning light. COMPONENT LOCATIONS Refer to illustration for SRS com
ponent locations. See
Fig. 1
&
Fig. 2
.
WARNING:Accidental air bag deployment is possible. Personal
injury may result. Read and follow all WARNINGS
and AIR BAG SAFETY PRECAUTIONS
before
working on air bag system or related components.

Observe these precautions when servicing the air bag system:
Disable SRS before servicing any SRS component. Failure to do this may
result in accidental air bag deployment and possible personal injury. See DISABLING & ACTIVATING AIR BAG SYSTEM
.
After disabling SRS, wait at least 60 seconds before servicing SRS. After servicing, always turn ignition on from outside of vehicle in case of
accidental air bag module deployment. After servicing, check AIR BAG warning light to verify system operation. See SYSTEM OPERATION CHECK
.
Always wear safety glasses when servicing or handling an SRS component. Hearing protection must be worn when performing deployment procedures. DO NOT expose air bag modules, clockspring or SRS ECU to temperatures
greater than 200°F (93°C ). DO NOT expose seat belt pretensioners to temperatures greater than 194°F
(90°C ). When placing a live air bag module on a bench or other surface, always place
air bag module with trim cover facing up and away from surface. This will
reduce motion of air bag module if accidental deployment occurs. After air bag module deploys, surrounding surfaces may contain deposits of
sodium hydroxide, which irritates skin. Always wear safety glasses, rubber
gloves and a long-sleeved shirt during clean-up. Wash hands using mild soap
and water. Follow correct clean-up and disposal procedures. See
DISPOSAL
PROCEDURES
.
Because of critical system operating requirements, DO NOT service any SRS
components. Repairs are only made by replacing defective components. DO NOT allow any electrical source near inflator on back of air bag module. When carrying a live (undeployed) air bag module, trim cover must be pointed
away from body to minimize injury in case of accidental air bag deployment. If instructed to probe wire harness, do so from harness side of connector. DO NOT probe a wire through insulator. Wire will be damaged and eventually
fail due to corrosion. When
performin
g electrical tests,
prevent accidental shortin
g of terminals.

leads. Wrap connections with electrical tape.
3. Secure driver-side air bag module to an old tire and wheel. Run harness wires
through hole at rear of air bag module, through hole in wheel and out beneath
tire. Stack 3 more tires on top of first tire. Tie tires together with rope in four
locations. Untwist ends of deployment harness. Connect ends of deployment
harness to terminals of a 12-volt battery to deploy air bag module. If air bag
module fails to deploy, go to step 7 . If air bag module deploys, wait at least 30
minutes for air bag module to cool before touching. Go to next step.
4. Remove remaining components. See
REMOVAL & INSTALLATION
. For
passenger-side air bag modules and seat belt pretensioners, place component
on ground at least 20 feet (6.1 m) away from people or objects. Ensure trim
cover of passenger-side air bag module is facing up. For side impact air bag
modules, position seat back so rear of seat back is in contact with ground
surface, at least 20 feet (6.1 m) away from people or objects.
5. Make a deployment harness using two wires at least 20 feet (6.1 m) in length.
Temporarily twist wires on one end of harness together to prevent unexpected
deployment. Connect wires at other end of harness to stripped wires of SRS
Air Bag Adapter Harness "B" (MB686560) for passenger-side or side impact
air bag modules or SRS Air Bag Adapter Harness (MR991885) for seat belt
pretensioners.
6. Wrap connections with insulating tape. Connect appropriate adapter harness to
component connector. If deploying passenger-side air bag module or seat belt
pretensioner, secure component to a scrap tire and wheel. Run harness wires
through air bag module mounting hole, through hole in wheel and out beneath
tire. Stack 3 more tires on top of first tire. Tie tires together with rope in four
locations.
7. To deploy appropriate component, connect ends of deployment harness to
terminals of a 12-volt battery. If any component fails to deploy, stay away from
component. Contact manufacturer for further instructions. After deployment,
allow at least 30 minutes for component to cool before touching. Tightly seal
deployed component in a strong plastic bag and dispose of it as you would any
other part.
