SERVICE PRECAUTIONS
The DERM can maintain sufficient volt age to cause a deployment for up to 10
minutes after the ignition switch is tur ned OFF or the battery is disconnected.
Always disable the system when perfo rming service procedures ON OR NEAR
the system and it's components.
CAUTION - The disarming and arming procedures must be followed in the
order listed to temporarily disable the SI R system. Failure to do so could result
in possible air bag deployment, pers onal injury or otherwise unneeded SIR
system repairs.
DISARMING THE SYSTEM
1. Turn the steering wheel so that t he vehicle's wheels are pointing straight
ahead.
2. Turn the ignition switch to the LOCK position.
3. Remove the SIR or AIR BAG fuse from the fuse panel.
4. Remove the left side trim panel, t hen remove the Connector Position
Assurance (CPA) device and disconnec t the yellow two-way SIR harness
connector at the base of the steering column.
5. On vehicles with passenger side air bags, remove the glove box door
then disconnect the yellow two-way c onnector located near the yellow
24-way DERM harness connector.
With the fuse removed and the ignition sw itch ON, the air bag warning lamp will
be on. This is normal and does not indicate a SIR system malfunction.

ARMING THE SYSTEM
1. Turn the ignition key to the LO CK position and remove the key.
2. On vehicles with a passenger side ai r bag, reconnect the yellow two-way
connector assembly located near the yellow 24-way DERM harness
connector. Install the glov e box door assembly.
3. Connect the yellow two-way connector assembly at the base of the
steering column.
Always be sure to reinstall the Connec tor Position Assurance (CPA) device.
4. Install the left side trim panel and rein stall the fuse in the fuse block.
5. Turn the ignition key to the RUN posit ion and verify that the warning lamp
flashes seven to nine times and then turn s OFF. If it does not operate as
described, have the system repair ed by a qualified technician.
HEATING AND AIR CONDITIONING

BLOWER MOTOR
REMOVAL & INSTALLATION 1. Disconnect the negative battery cable. If necessary, remove the diagonal
fender brace at the right rear corner of the engine compartment to gain
access to the blower motor.
2. Disconnect the electrical wiring fr om the blower motor. If equipped with
air conditioning, remove the blower relay and bracket as an assembly
and swing them aside.
3. Remove the blower motor cooling tube.
4. Remove the blower mo tor retaining screws.
5. Remove the blower motor and fan as an assembly from the case.
To install: 6. Position the blower motor into pl ace and install the retaining screws.
7. Install the blower motor cooling tube.

recommended to have a qualified technici
an perform any further testing, if
needed.
FIELD SERVICE MODE
On fuel injected models, if the ALDL terminal B is grounded to terminal A with
the engine running, the system enters the Field Service Mode. In this mode, the
MIL will indicate whether the system is operating in open loop or closed loop.
If working in open loop, t he MIL will flash rapidly 2
1/2 times per second. In
closed loop, the flash rate slows to once per second. Additionally, if the system
is running lean in closed loop, the lamp will be off most of the cycle. A rich
condition in closed loop will cause the lamp to remain lit for most of the one
second cycle.
When operating in the Field Service M ode, additional codes cannot be stored
by the ECM. The closed loop timer is bypassed in this mode.
CLEARING CODES
Stored fault codes may be erased from me mory at any time by removing power
from the ECM for at least 30 seconds. It may be necessary to clear stored
codes during diagnosis to check for any re currence during a test drive, but the
stored should be written dow n when retrieved. The codes may still be required
for subsequent troubleshooting. Whenever a repair is complete, the stored
codes must be erased and the vehicle te st driven to confirm correct operation
and repair.
The ignition switch must be OFF any ti me power is disconnected or restored to
the ECM. Severe damage may result if this precaution is not observed.
Depending on the electric di stribution of the particular vehicle, power to the
ECM may be disconnected by removing the ECM fuse in the fusebox or
disconnecting the inline EC M power lead at the positive battery terminal.
Disconnecting the negative battery cable to clear codes will achieve the desired
result, but this will also clear other me mory data in the vehicle such as radio
presets or seat memory.
