< FUNCTION DIAGNOSIS >[WITH INTELLIGENT KEY SYSTEM]
INTELLIGENT KEY SYSTEM/ENGINE START FUNCTION
• Intelligent Key has 2 IDs (for Intelligent Key and for
NATS). It can perform the door lock/unlock operation and
the engine start operation when the registered Intelligent Key is carried.
• When the Intelligent Key battery is discharged, it can be used as emergency back-up by inserting the
mechanical key set in the Intelligent Key to the ignition key cylinder. At that time, perform the NATS ID verifi-
cation. If it is used when the Intelligent Key is carried, perform the Intelligent Key ID verification.
• If the ID is successfully verified, and when the igniti on knob switch is pressed, steering lock will be released
and initiating the engine will be possible.
• The door lock/unlock operation can be performed when the Intelligent Key battery is discharged, by operat-
ing the driver door key cylinder using the mechanical key set in the Intelligent Key.
• Up to 4 Intelligent Keys can be registered (including the standard Intelligent Key) on request from the owner. NOTE:
• Refer to DLK-21, "
INTELLIGENT KEY : System Description" for any functions other than engine start func-
tion of Intelligent Key system.
PRECAUTIONS FOR INTELLIGENT KEY SYSTEM
• For vehicles equipped with the Intelligent Key system , the transponder [the chip for NATS ID verifi-
cation] is integrated into the Inte lligent Key. Therefore, the Intellig ent Key alone is capable of provid-
ing security clearance for the engine to start. Also, when the mechanical key alone is inserted into
the key cylinder, performs the NATS ID verification to allow the engine to start. For vehicles without
Intelligent Key system, the transponder is integrated into the mechanical key which must be inserted
into the key cylinder to perform the NATS ID verification to allow the engine to start.
OPERATION WHEN INTELLIGENT KEY IS CARRIED
1. When the ignition knob switch is ON, the Intelligent Key unit transmits the request signal to the Intelligent
Key.
2. The Intelligent Key receives the request signal and transmits the Intelligent Key ID signal to the Intelligent Key unit.
3. The Intelligent Key unit receives the Intelligent Key ID signal and verifies it with the registered ID.
4. Intelligent Key unit transmits the steering lock/unlock signal to steering lock solenoid if the verification results are OK. For detail of key warning message operation, refer to DLK-38, "
System Description".
5. Release of the steering lock.
6. BCM transmits the starter request signal via CAN communication to IPDM E/R and turns the starter relay in IPDM E/R ON if BCM judges that the engine start condition is satisfied.
7. IPDM E/R turns the starter control relay ON when receiving the starter request signal.
8. When shift position is in P or N position, battery power is supplied through the starter relay and operate the starter motor and to start the cranking.
CAUTION:
If a malfunction is detected in the Intelligent Key system, the “KEY” warning message will be dis-
played in the combination meter. At th at time, the engine cannot be started.
OPERATION RANGE
Engine can be started when Intelligent Key is inside the vehicle. However, sometimes engine might not start
when Intelligent Key is on instrument panel or in glove box.
OPERATION WHEN MECHANICAL KEY IS USED
When the Intelligent Key battery is discharged, performs the NATS ID verification between the integrated tran-
sponder and BCM by inserting the mechanical key into the key cylinder, and then the engine can be started.
For details relating to starting the engine using mechanical key, refer to SEC-11, "
System Description".
STEERING LOCK OPERATION
Steering is locked by steering lock solenoid when ignition switch is in the LOCK position (the ignition knob is
released) and key switch is OFF (key is removed from ignition key cylinder).

FRONT PASSENGER AIR BAG MODULE
FRONT PASSENGER AIR BAG MODULE
Removal and InstallationINFOID:0000000003775159
The passenger air bag module originally installed in the vehicle uses direct-connect style harness connectors.
Service replacement passenger air bag modules use tab-locking style harness connectors. If the passenger
air bag module is replaced or if the direct-connect harness connectors are damaged, the vehicle wiring har-
ness must be modified to allow connection of the service replacement passenger air bag module. Follow the
wiring harness modification procedure within this section.
REMOVAL
CAUTION:
• Do not attempt to repair or replace damaged di rect-connect front passenger air bag module connec-
tors. If a direct-connect harness connector is damaged, the front passenger air bag must be
replaced and the wiri ng harness modified.
• Before servicing SRS, turn the ig nition switch off, disconnect both battery terminals and wait at least
three minutes.
• Always work from the side of or under front passenger air bag module.
1. Disconnect both the negative and positive battery terminals, then wait at least three minutes.
2. Remove the glove box. Refer to IP-17, "
Exploded View".
3. Remove two nuts (through glove box opening) retaining front passenger air bag module to instrument panel crossmember.
4. Disconnect the air bag module electrical connectors. • For removal/installation of the direct-connect SRS connectors, refer to SRC-9, "
Direct-connect SRS
Component Connectors".
5. Remove the instrument panel assembly from the vehicle. Refer to IP-13, "
Removal and Installation".
6. Remove front passenger air bag module nuts and remove air bag module from the instrument panel assembly.
CAUTION:
• When servicing the SRS, do not work from directly in front of
air bag module.
• Always place front passenger air bag module with caution label side facing upward.
• Do not insert any foreign object s (screwdriver, etc.) into air
bag module or harness connectors.
• Do not disassemble air bag module.
• Do not use old nuts after removal; replace with new nuts.
• Do not expose the front passenger air bag module to tempera- tures exceeding 90 °C (194 °F).
