WARNING:
Before servicing, turn ignition switch OFF, disconnect battery ne gative terminal and wait 3 minutes
or more.
Before disconnecting the air bag diagnosis sensor unit harness conn ectors, be sure to disconnect
the each harness connector of the air bag module and seat belt pre-tensioner to prevent air bag
deployment by static electricity and seat belt pre-tensioner operation.
Never use the air tools or electric tools for servicing.
When replacing the air bag diagno sis sensor unit, always check with th e parts department for the lat-
est parts information. Installing an incorrect air bag diagnosis sen sor unit may or may not cause the
air bag warning lamp to illuminate and may cause in correct deployment of the supplemental air bags
and seat belt pre-tensioners in a collision r esulting in serious personal injury or death.
REMOVAL
1. Always check the air bag diagnosis sensor unit E CU discriminated number (identification number) using
CONSULT-III.
2. Disconnect the each connector of all air bag modules and pre-tensioner seat belts.
3. Remove the console finisher assembly. Refer to IP-25, "
Removal and Installation".
4. Remove the diagnosis sensor unit fixing bolts, ground bolt, and then remove diagnosis sensor unit.
5. Disconnect the diagnosis sensor unit harness connector.

DIAGNOSIS SYSTEM (AIR BAG)
DescriptionINFOID:0000000006219952
CAUTION:
Never use electrical test equipment on any circuit related to the SRS unless instructed in this Ser-
vice Manual. SRS wiring harnesses can be identifi ed by yellow and/or orange harnesses or harness
connectors.
Never repair, splice or modify the SRS wiring harn ess. If the harness is damaged, replace it with a
new one.
Keep ground portion clean.
DIAGNOSIS FUNCTION
The SRS self-diagnostic results can be read with air bag warning lamp and/or CONSULT-III.
The user mode is exclusively prepared for the customer (driver). This mode warns the driver of a system
malfunction through the operation of the air bag warning lamp.
The diagnosis mode allows the technician to locate and inspect the malfunctioning part.
The mode applications for the air bag warning lamp and CONSULT-III are as per the following items.

ON-BOARD DIAGNOSIS
There are two self diagnosis functions with air bag warning lamp per the following items.
USER MODE
DIAGNOSIS MODE
METHOD OF STARTING
Diagnosis mode changes from user mode to di agnosis mode when changing operation is performed.
In user mode, when SRS air bag warning lamp is not blinking, changing to diagnosis mode by ignition switch
operation is not possible.
In diagnosis mode, when repair is complete and system is normal, the mode changes to user mode when
ignition switch is turned from OFF to ON.
Procedure to Change Diagnosis Mode
1. Turn ignition switch from OFF to ON.
2. SRS air bag lamp turns ON for 7 second and turns OFF, then turn ignition switch OFF within 1second after the lamp turns OFF.
3. After turning ignition switch OFF, wait for 3 seconds or more.
4. Repeat operation 1 to 3 for 2 times so that operation 1 to 3 is repeated for 3times in total.
5. Turn ignition switch from OFF to ON. Diagnosis mode changes.
USER MODE
In USER MODE, air bag warning lamp on combination meter blinks when a malfunction is detected and warns
the customer (driver).
How to Read Air Bag Warning Lamp
1. Turn the ignition switch from OFF to ON, and check that the air bag warning lamp blinks.
2. Compare the air bag warning lamp blinking pattern with the examples.
