HINT:
When the SRS warning light remains lit up and the DTC is the normal code\
, this means a source drop
voltage.
This malfunction is not stored in memory by the airbag sensor assembly a\
nd if the power source volt-
age returns to normal, the SRS warning light will automatically go out.
When 2 or more codes are indicated, the codes will be displayed in numer\
al order starting from the
lowest numbered code.
If a code not listed on the chart is displayed, the airbag sensor assemb\
ly is faulty.

CIRCUIT DESCRIPTION
The squib circuit consists of the airbag sensor assembly, spiral cable, steering wheel pad and front passen-
ger airbag assembly. If causes the SRS to deploy when the SRS deployment conditions are sat\
isfied.
For details of the function of each component, see FUNCTION OF COMPONENT\
S on page RS−2.

4 Check airbag sensor assembly.
PREPARATION:
(a) Connect connector to airbag sensor assembly.
(b) Using service wire, connect D
+ and D− on spiral cable side
of connector between spiral cable and steering wheel
pad.
(c) Using a service wire, connect P
+ and P− on airbag sensor
assembly side of connector between airbag sensor as-
sembly and front passenger airbag assembly.
(d) Connect negative ( −) terminal cable to battery, and wait
at least 2 seconds.
CHECK:
(a) Turn ignition switch to ACC or ON and wait at least 20 se-
conds.
(b) Clear malfunction code stored in memory. (See page DI−240 )
(c) Turn ignition switch to LOCK, and wait at least 20 se- conds.
(d) Turn ignition switch to ACC or ON, and wait at least 20 se-
conds.
(e) Using SST, connect terminals Tc and E1 of DLC1. SST 09843−18020
(f) Check DTC
OK:
DTC 11 is not output.
HINT:
Codes other than code 11 may be output at this time, but they
are not relevant to this check.
NG Replace airbag sensor assembly.
OK
