PASSENGER AIR BAG DEACTIVATION SWITCH (2-DOOR MODELS)

The vehicle (2-door models) is equipped with a passenger air bag deactivation switch which can be operated
by the customer. When the switch is turned to the ON position, the passenger air bag is enabled and could
inflate in a frontal collision. When the switch is turned to the OFF position, the passenger air bag is disabled
and will not inflate in a frontal collision.
After turning the ignition switch ON, the passenger air bag deactivation switch indicator on the instrument
panel illuminates for bulb check. The indicator will remain illuminated if the passenger air bag deactivation
switch is in the OFF position. If the passenger air bag deactivation switch is in the ON position, the indicator
will turn off after about 7 seconds.
After SRS maintenance or repair, make sure the passenger air bag
deactivation switch is in the same position (ON or OFF) as when the
vehicle arrived for service.

Trouble Diagnoses Introduction

EHS000SV

CAUTION:

●

Do not use electrical test equipment on any circuit related to the SRS unless instructed to in this
Service Manual. SRS wiring harnesses can be identified by yellow and/or orange harness connec-
tors.

●

Do not attempt to repair, splice or modify the SRS wiring harness. If the harness is damaged,
replace it with a new one.

●

Keep ground portion clean.

DIAGNOSIS FUNCTION

The SRS self-diagnosis results can be read by using “AIR BAG” warning lamp and/or CONSULT-II. The read-
ing of these results is accomplished using one of two modes — “User mode” and “Diagnosis mode”.
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:

NOTE:
Seat belt pre-tensioner malfunction is indicated by “AIR BAG” warning lamp.

DIAGNOSIS MODE FOR CONSULT-II

●

“SELF-DIAG [CURRENT]”
A current Self-diagnosis result (also indicated by the number of warning lamp flashes in the Diagnosis
mode) is displayed on the CONSULT-II screen in real time. This refers to a malfunctioning part requiring
repairs.

●

“SELF-DIAG [PAST]”
Diagnosis results previously stored in the memory are displayed on the CONSULT-II screen. The stored
results are not erased until memory erasing is executed.

●

“TROUBLE DIAG RECORD”
With TROUBLE DIAG RECORD, diagnosis results previously erased by a reset operation can be dis-
played on the CONSULT-II screen.

●

“ECU DISCRIMINATED NO.”
The diagnosis sensor unit for each vehicle model is assigned
with its own, individual classification number. This number will
be displayed on the CONSULT-II screen, as shown. When
replacing the diagnosis sensor unit, refer to the part number for
the compatibility. After installation, replacement with a correct
unit can be checked by confirming this classification number on
the CONSULT-II screen.
