RESISTANCE AND CONTINUITY BETWEEN HARNESS-SIDE CONNECTOR TERMINALS 1. Disconnect the connector A-02, and connect special tool ABS Check Harness
(MB991970) to the wiring harness-side connector.
2. Measure the resistance and continuity between the terminals indicated in the
table below. NOTE: Do not measure terminal voltage for approximately three
seconds after the ignition switch is turned "ON." The ABS-
ECU performs the initial check during that period.
NOTE: Do not connect special tool ABS Check Harness
(MB991970) to the ABS-ECU.

1. Jack up the vehicle. Then support the vehicle with rigid racks at the specified
jack-up points or place the front or rear wheels on the rollers of the braking
force tester.
2. Release the parking brake, and feel the drag force (drag torque) on each road
wheel. When using the braking force tester, take a reading of the brake drag
force.
3. Connect scan tool MB991958 to the data link connec
tor. also under special conditions, such as driving on a rough
road.
NOTE: For vehicles with ASC, refer to HYDRAULIC UNIT CHECK
.
CAUTION:
The roller of the braking force tester and the tire
should be dry during testing. When testing the front brakes, apply the parking
brake. When testing the rear brakes, stop the
front wheels with chocks.
CAUTION: To prevent damage to scan tool MB991958,
always turn the ignition switch to the
"LOCK" (OFF) position before connecting or
disconnecting scan tool MB991958.

2. With the ignition switch turned to the "ON" position, read the voltage between
terminals number 2 and number 3.
Standard Value: 2.4 - 2.6 V
3. With special tool MB991348 connected, rotate so that the arrow points straight
down. Read output voltage between terminals number 2 and number 3.
Standard Value: 3.4 - 3.6 V
4. If the voltage deviates from the standard value, check the power supply wire
and ground wire. If no problems are found, replace the G-sensor. SPECIFICATIONS FASTENER TIGHTENING SPECIFICATION FASTENER TIGHTENING SPECIFICATION GENERAL SPECIFICATIONS Fig. 166: General Specifications

SYSTEM OPERATION CHECK Turn ignition on. AIR BAG warning light should come on for about 7 seconds and
then turn off, indicating SRS is functioning properly. If AIR BAG warning light
does not function as described, SRS is malfunctioning and needs repair. See DIAGNOSTICS
.
AIR BAG SAFETY PRECAUTION
S
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.

Such shorts can damage fuses or components and may cause a second
Diagnostic Trouble Code (DTC) to set, making diagnosis of original problem
more difficult. Never use an analog volt/ohm meter or test light in place of a Digital Volt/Ohm
Meter (DVOM). Use only a DVOM with a maximum test current of 2 mA
(milliamps) at minimum range of resistance measurement. If SRS is not fully functional for any reason, DO NOT drive vehicle until
system is repaired and fully functional. DO NOT remove bulbs, modules,
sensors, or other components or in any way disable system from operating
normally. If SRS is not functional, park vehicle until repairs are made.
DISABLING & ACTIVATING AIR BAG SYSTEM To disable system, turn ignition off. Disconnect negative battery cable. Shield cable
end with electrical tape. Wait at least 60 seconds before servicing air bag system.
To activate system, reconnect negative battery cable. Check system operation. See SYSTEM OPERATION CHECK
.
DISPOSAL PROCEDURES DEPLOYED AIR BAG OR SEAT BELT PRETENSIONER Place deployed component in a strong plastic bag and seal tightly. Dispose of
component as you would any other part. No other special disposal procedure is
required. UNDEPLOYED AIR BAG OR SEAT BELT PRETENSIONER
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.
NOTE: Undeployed air bag modules must be deployed before
disposal. Disposing of an undeployed air bag may violate
federal, state and/or local laws. This also applies to vehicles
that are to be scrapped.

length. Strip insulation from ends of wires. Connect wires at one end of harness
to clockspring connector stripped wires and cover connections with insulating
tape. Temporarily wrap other end of harness wires together to prevent
unexpected air bag deployment.
7. Stretch deployment harness as far away from vehicle as possible. Roll up
vehicle windows to lessen deployment noise and cover vehicle with car cover,
in case glass should shatter during deployment. Ensure area is clear of people.
Untwist deployment harness wire ends. Touch wire ends to 12 volt battery
terminals to deploy driver-side air bag module.
8. Repeat procedure for remaining air bag modules and seat belt pretensioners.
Use SRS Air Bag Adapter Harness (MB686560) for passenger-side and side
impact air bag modules. Use SRS Adapter Harness (MR991885) for seat belt
pretensioners. If any component fails to deploy, stay away from vehicle and
contact manufacturer for further instructions. Allow 30 minutes for air bag
modules to cool.
Off-vehicle Deployment 1. Before proceeding, see
AIR BAG SAFETY PRECAUTIONS
. Turn ignition
switch to LOCK position. Disconnect negative battery cable. Shield cable end.
Wait at least 60 seconds before continuing. Disconnect positive battery cable.
Remove battery from vehicle.
2. Fabricate a deployment harness using two wires at least 20 feet (6.1 m) in
length. Strip insulation from ends of wires. Twist together one end of wires
temporarily. Remove driver-side air bag module. See
DRIVER
-SIDE AIR
BAG MODULE & CLOCKSPRING
under REMOVAL &
INSTALLATION. Place driver-side air bag module on surface face up. Touch
vehicle body with bare hands to discharge static electricity from body. Cut
driver-side air bag module connector from pigtail leads. Strip insulation from
ends of
pigtail wires. Attach remainin
g ends of de
ployment harness to
pigtail NOTE: Driver-side and passenger-side air bag modules will be
either single-stage or dual-stage. Consult wiring
diagrams to ensure correct wires are cut and spliced
prior to deployment. See WIRING DIAGRAMS
