Removal and InstallationEIS00C62
REMOVAL
When removing or installing the seat trim, handle it carefully to keep dirt out and avoid damage.
CAUTION:
lBefore removing the front seat, turn the ignition switch off, disconnect both battery cables and
wait at least 3 minutes.
lWhen checking the power seat circuit for continuity using a circuit tester, do not confuse its con-
nector with the side air bag module connector. Such an error may cause the air bag to deploy.
lDo not drop, tilt, or bump the side air bag module while installing the seat. Always handle it with
care.
lAfter front side air bag module inflates, front seatback assembly must be replaced.
1. Slide the seat backward, and then remove the seat slide cover
cap(1) and rear leg cover(2), and then remove the seat mount-
ing bolts.
2. Slide the seat forward, and then open the seat slide cover
cap(1) and remove the front leg cover(2), and then remove the
seat mounting bolts.
NOTE:
If disassembling the seat after removal, set the front/rear cush-
ion lifters to the top position.
3. Disconnect both battery cables and wait at least 3 minutes.
4. Disconnect the side air bag module harness connector.
5. Disconnect the power seat harness connectors and remove the seat from the vehicle.
NOTE:
When removing and installing the seat, use shop cloths to protect the vehicle from damage.

Trouble Diagnosis IntroductionEHS001XG
CAUTION:
lDo not use electrical test equipment on any circuit related to the SRS unless instructed to do so in
this Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness con-
nectors.
lDo not attempt to repair, splice or modify SRS wiring harnesses. If a harness is damaged, replace
it with a new one.
lKeep ground connections clean.
DIAGNOSIS FUNCTION
The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II.
The User mode is exclusively prepared for the customer (driver). This mode warns the driver of a system mal-
function 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-II are as follows:
HOW TO PERFORM TROUBLE DIAGNOSES FOR QUICK AND ACCURATE REPAIR
A good understanding of the malfunction conditions can make troubleshooting faster and more accurate.
In general, each customer feels differently about a malfunction. It is important to fully understand the symp-
toms or conditions for a customer complaint.

DIAGNOSTIC PROCEDURE 7
1.CHECK CONDITION OF AIR BAG MODULES
Inspect for any deployed air bag modules or seat belt pre-tensioners.
Are any air bag modules or seat belt pre-tensioners deployed?
Yes >> Refer toSRS-56, "COLLISION DIAGNOSIS".
No >> GO TO 2.
2.CHECK THE AIR BAG FUSE
Check 10A fuse [No. 13, located in the fuse block (J/B)].
Refer toPG-4, "
POWER SUPPLY ROUTING CIRCUIT".
OK or NG
OK >> GO TO 4.
NG >> GO TO 3.
3.CHECK AIR BAG FUSE AGAIN
Replace 10A fuse [No. 13, located in the fuse block (J/B)] and turn ignition switch ON.
Does the fuse blow again?
Yes >> Repair or replace main harness.
No >> Inspection End.
4.CHECK AIR BAG DIAGNOSIS SENSOR UNIT
Connect CONSULT-II and CONSULT-II CONVERTER and touch
“START”.
Is
“AIR BAG”displayed on CONSULT-II?
Yes >>GOTO5.
No >> Visually inspect the air bag diagnosis sensor unit har-
ness connections. If the connections are OK, replace
the air bag diagnosis sensor unit. Refer toSRS-48,
"Removal and Installation".
5.CHECK HARNESS CONNECTION
Check for loose connections between the combination meter and the air bag diagnosis sensor unit.
OK or NG
OK >> Replace air bag diagnosis sensor unit. Refer toSRS-48, "Removal and Installation".
NG >> Properly connect the combination meter and air bag diagnosis sensor unit harness connectors. If
“AIR BAG” warning lamp still does not turn off, replace the wiring harness.
