"AIR BAG" WARNING LAMP DOES NOT COME "ON"
CIRCUIT DESCRIPTION
When the ignition switch is first turned "ON," "Ignition 1"
voltage is applied from the "C-21" fuse to "Redundant
Indicator Ignition 1 ,"terminal "B2", and to the "AIR BAG"
warning lamp which is connected to "SRS Indicator,"
terminal "B1".
The "C-22·C-23" fuses apply system
voltage to the "Ignition 1" inputs, terminals "A9"
and"A10". The DERM responds by flashing the "AIR
BAG"
warning lamp seven times.When the engine is
being cranked,
"Starter'' voltage is applied from the "C-1"
fuse to the DERM at the "Crank" input. The DERM
responds by grounding the
"SRS Indicator'' output until
"Starter" voltage
is removed from the "Crank" input. This
results in the "ARE BAG" warning lamp being "ON"
during cranking.After cranking, the DERM will flash the
"AIR BAG" warning lamp six times.

DISCRIMINATING SENSOR OPEN OR MISSING
CIRCUIT DESCRIPTION
During normal, non-deployment operation of SRS a
small amount of current flows through both the driver and
passenger deployment loops.The diagnostic resistors
within the dual pole arming sensor and the discriminating
sensors along with the resistance of the inflator modules
cause voltage drops within the deployment loops.The
DERM monitors the voltage at "Driver Side
Low" terminal
"B8" and "Passenger Side Low" terminal "B7' to detect
shorts or opens within the deployment loops.When the
measured voltage at either terminal is within a specified
percentage of its respective
"36 VLR" power supply
voltage for
500 milliseconds DTC 35 is set.
DTC WILL SET WHEN
The voltage measured at "Driver Side Low" terminal "B8"
and "Passenger Side Low" terminal "B7" is within a
specified percentage
of its respective "36 VLR"a power
supply voltage for
500 milliseconds. This test is run every
1
00 milliseconds during the "Continuous Monitoring"
tests.
ACTION TAKEN
DERM turns "ON" the "AIR BAG" warning lamp and sets
a diagnostic trouble code.
...
DTC WILL CLEAR WHEN
The voltages measured at "Driver Side Low" terminal
"B8" and "Passenger Side Low" terminal "B7" are both
above or
below the respective "36 VLR" power supply
voltage which sets
DTC 35.
DTC CHART TEST DESCRIPTION
Number(s) below refer to step number(s) on the
diagnostic chart.
2. This test checks for an open inside the forward LH
discriminating sensor.
3. This test checks for an open inside the
Eng-ROOM(forward LH discriminating sensor
Jumper) HARNESS.
4. This test checks for an open inside the forward RH
discriminating sensor.
5. This test checks for an open inside the Engine room
(forward
RH Discriminating Sensor Jumper)
DIAGNOSTIC AIDS
An intermittent condition is likely to be an improper
connection at any of the discriminating sensor terminals,
an open in either ground feed to the discriminating
sensors,
an open discriminating sensor interconnect
ciircuit, increased resistance
of any discriminating
sensor or decreased resistance of the dual pole arming
sensor.

SRS COIL ASSEMBLY
WARNING: SAFETY PRECAUTIONS MUST BE FOLLOWED WHEN HANDLING A DEPLOYED INFLATOR
MODULE{AIR
BAG). AFTER DEPLOYMENT, THE INFLATOR MODULE{AIR BAG) SURFACE MAY CONTAIN A
SMALL AMOUNT OF SODIUM HYDROXIDE, A BY-PRODUCT OF THE DEPLOYMENT REACTION, THAT IS
IRRITATING TO
THE SKIN AND EYES. MOST OF THE POWDER ON THE INFLATOR MODULE (AIR BAG )IS
HARMLESS.
AS A PRECAUTION, WEAR GLOVES AND SAFETY GLASSES WHEN HANDLING A DEPLOYED
INFLATOR MODULE {AIR BAG ), AND WASH YOUR HANDS WITH MILD SOAP AND WATER AFTERWARDS.
WARNING: WHEN CARRYING A LIVE INFLATOR MODULE {AIR BAG ), MAKE SURE THE BAG AND TRIM
COVER
ARE POINTED AWAY FROM YOU. NEVER CARRY INFLATOR MODULE {AIR BAG )BY THE WIRES OR
CONNECTOR ON
THE UNDERSIDE OF MODULE. IN THE CASE OF AN ACCIDENTAL DEPLOYMENT, THE BAG
WILL THEN DEPLOY WITH MINIMAL CHANCE OF INJURY. WHEN PLACING A LIVE INFLATOR MODULE (AIR
BAG ) ON A BENCH OR OTHER SURFACE, ALWAYS FACE BAG AND TRIM COVER UP, AWAY FROM THE
SURFACE. NEVER REST A STEERING COLUMN ASSEMBLY ON THE STEERING WHEEL WITH THE INFLATOR
MODULE (AIR BAG) FACE DOWN AND COLUMN VERTICAL. THIS IS NECESSARY SO THAT A FREE SPACE
IS PROVIDED TO
ALLOW THE INFLATOR MODULE { AIR BAG ) TO EXPAND IN THE UNLIKELY EVENT OF
ACCIDENTAL
DEPLOYMENT. OTHERWISE, PERSONAL INJURY COULD RESULT.
NOTE:
In the event deployment has occurred, inspect coil assembly wire for any signs of scorching, melting or any
other damage due to excessive heat.
If the coil has been damaged, replace it.
REMOVAL ~------------------------------------------,
1. Disable the SRS. (Refer to "Disabling the SRS"
in this section.)
2. Remove the transmission knob(for
MIT) and
transfer
control knob.
3. Remove front console assembly and disconnect
the wiring harness connector.
4. Remove the steering lower cover and engine
hood opening
lever.
5. Remove inflator module (Air Bag) from steering
wheel by removing four bolts. Lift inflator module
(Air Bag) out of steering wheel.
6. Disconnect connector and remove inflator
module (Air Bag).
7. Disconnect horn lead
8. Remove steering wheel attachment nut.
9. Apply a setting mark across the steering wheel
and shaft so parts can be reassembled in their
original position.
10. Move the tires to the straight ahead position
before removing the steering
wheel and install
steering wheel puller onto steering wheel and
remove steering
wheel with J-29752.
11. Feed wiring through the wheel and remove
wheel.
CAUTION:
NEVER APPLY FORCE TO THE
STEERING WHEEL IN DIRECTION OF THE SHAFT
BY USING A HAMMER OR OTHER IMPACT TOOLS
~ IN AN ATTEMPT TO REMOVE THE STEERING
WHEEL. THE STEERING SHAFT IS DESIGNED AS
AN ENERGY ABSORBING UNIT.
