1CHECK HARNESS.
1) Disconnect the CAN junction connector
(i128) and body integrated unit connector (i84).
2) Measure the resistance between connector
terminals.
Connector & terminal
(i84) No. 26 — (i128) No. 7 to 12:
(i84) No. 27 — (i128) No. 1 to 6:
NOTE:The i128 junction connector is freely arranged.
Is the resistance less than 10
Ω?
Go to step 2.Repair the short
circuit of harness
or replace har-
ness.

1 CHECK POOR CONTACT OF CONNEC-
TORS.
Check for poor contact of the connectors
between the occupant detection control mod-
ule and belt tension sensor.
Is there poor contact? Reconnect the
connector. If the
fault is not fixed,
replace the airbag
harness.
Go to step 2.
2CHECK THE BELT TENSION SENSOR.
1) Turn the ignition switch to OFF, disconnect
the battery ground cable, and wait more than
20 seconds.
2) Disconnect the belt tension sensor connec-
tor (AB56) from the airbag harness.
3) Connect the test harness AC to the con-
nector (AB56).
4) Connect the battery ground terminal and
turn the ignition switch to ON.
Does the airbag warning light
illuminate for approximately 6
seconds and go off?
Replace the seat
belt outer.

•Failure turn of glass lid while driving rough road.
Glass lid has auto-reverse function. When applied above specified force to the glass lid, the lid turns back
and stops. When operating the glass lid (open or close) while driving the rough road, the lid judges vibration
as a force and may causes failure turns. When the failure turn is occurred, need to perform the initialize op-
eration with following procedure.
1. INITIALIZE OPERATION
1) Tilt up the glass lid.
2) Release the switch once, and press the tilt up switch again for 15 seconds.
3) When the glass lid is raised a little and returned to tilt up position, release the switch for the moment. (Ini-
tialization of position detecting function)
4) Holding down the tilt up switch again within 5 seconds from releasing the switch will automatically perform
tilt down/slide open/slide close. (When more than 5 seconds pass, the position detecting function is can-
celled.)
5) Initialize operation is completed.

Tire Pressure Warning Light/Trouble Indicator Light Illumination Pattern (DTC)
TIRE PRESSURE MONITORING SYSTEM (DIAGNOSTICS)
1) When the tire pressure warning light does not illuminate in accordance with this illumination pattern, there
must be an electrical malfunction.
2) When tire pressure warning light does not go off, check the tire pressure monitoring control module/warn-
ing light circuit and the combination meter circuit.

NOTE:
If the problem is fixed while driving at approximately 40 km/h (25 MPH) after the tire pressure warning light
blinks/lights, the warning light goes out and the tire pressure monitor system operates normally. (If there is
a decrease in tire pressure, or malfunction of the system, the past malfunctions are displayed.)
B: TIRE PRESSURE WARNING LIGHT DOES NOT ILLUMINATE
DETECTING CONDITION:
•Defective combination meter
•Defective harness
TROUBLE SYMPTOM:
When the ignition switch is turned to ON (engine OFF), the tire pressure warning light does not come on (for
approximately 2 seconds).
