DTC B1140/32 Side and Curtain Shield Airbag Sensor
Assembly RH Malfunction
CIRCUIT DESCRIPTION
The side and curtain shield airbag sensor assembly RH consists of the safing sensor, diagnosis circuit and
lateral deceleration sensor, etc.
It receives signals from the lateral deceleration sensor, judges whether or not the SRS must be activated,
and detects diagnosis system malfunction.
DTC B1140/32 is recorded when occurrence of a malfunction in the side and curtain shield airbag sensor
assembly RH is detected.

INSPECTION PROCEDURE
1 Is DTC B1140/32 output?
CHECK:
(a) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(b) Clear the DTC stored in memory (See page DI-692).
(c) Turn the ignition switch to LOCK, and wait at least for 10
seconds.
(d) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
DTC B1140/32 is output.
HINT:
Codes other than code B1140/32 may be output at this time, but
they are not relevant to this check.

normal. To make sure of this, use the simulation
method to check.
YES
2 Is connector of side and curtain shield airbag sensor assembly RH properly con-
nected?
NO Connect connector.
YES
3 Prepare for inspection (See step 1 on DI-923).

4 Check floor No. 2 wire.
PREPARATION:
Using a service wire, connect SSR+ and SSR- of the floor No.
2 wire connector on the side and curtain shield airbag sensor
assembly RH side.
CHECK:
Measure the resistance between SSR+ and SSR- of the floor
No. 2 wire connector on the airbag sensor assembly side.
OK:
Resistance: Below 1 W
NG Repair or replace floor No. 2 wire.

(b) Disconnect the negative (-) terminal cable from the bat-
tery, and wait at least for 90 seconds.
(c) Connect the connector to the airbag sensor assembly.
(d) Change the side and curtain shield airbag sensor assem-
bly LH position with RH position.
(e) Connect the negative (-) terminal cable to the battery,
and wait at least for 2 seconds.
CHECK:
(a) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(b) Clear the DTC stored in memory (See page DI-692).
(c) Turn the ignition switch to LOCK, and wait at least for 10
seconds.
(d) Turn the ignition switch to ON, and wait at least for 10 se-
conds.
(e) Check the DTC (See page DI-692).
OK:
Neither DTC B1140/32 nor B1141/33 are not output.
HINT:
Codes other than code B1140/32 or B1141/33 may be output
at this time, but they are not relevant to this check.
NG Replace airbag sensor assembly
(DTC B1140/32 is output).
NG Replace side and curtain shield airbag sensor
assembly RH (DTC B1141/33 is output).
