Check wire harness.
PREPARATION:
(a)
Disconnect the side airbag sensor assembly (RH) con-
nector.
(b)
Using a service wire, connect SSR+ and ESR of the con-
nector (on the side airbag sensor assembly side) between
the side airbag sensor assembly (RH) and airbag sensor
assembly.
CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the side airbag sensor assembly (RH) and the airbag
sensor assembly, measure the resistance between SSR+ and
ESR.
OK:
Resistance: Below 1 Ω
NG
Repair or replace harness or connector be-
tween side airbag sensor assembly (RH) and
airbag sensor assembly.
OK

Check wire harness.
PREPARATION:
Using a service wire, connect VUPR and FSR of the connector
(on the side airbag sensor assembly side) between the side air-
bag sensor assembly (RH) and airbag sensor assembly.
CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the side airbag sensor assembly (RH) and the airbag
sensor assembly, measure the resistance between VUPR and
FSR.
OK:
Resistance: Below 1 Ω
NG
Repair or replace harness or connector be-
tween side airbag sensor assembly (RH) and
airbag sensor assembly.

Check wire harness (to ground).
CHECK:
For the connector (on the airbag sensor assembly side) be-
tween the side airbag sensor assembly (RH) and the airbag
sensor assembly, measure the resistance between body
ground and each of SSR+, VUPR and FSR.
OK:
Resistance: Below 1 Ω
NG
Repair or replace harness or connector be-
tween side airbag sensor assembly (RH) and
airbag sensor assembly.
OK
7
Check wire harness (to B+).
CHECK:
(a)
Turn the ignition switch to ON.
(b)
For the connector (on the airbag sensor assembly side)
between the side airbag sensor assembly (RH) and the
airbag sensor assembly, measure the voltage between
the body ground and each of SSR+, VUPR, ESR and
FSR.
OK:
Voltage: 0 V
NG
Repair or replace harness or connector be-
tween side airbag sensor assembly (RH) and
airbag sensor assembly.

Is DTC B1140/32 out put again?
PREPARATION:
(a)
Connect the connector to the side airbag sensor assem-
bly (RH).
(b)
Connect the connector to the airbag sensor assembly.
(c)
Connect 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 20 se-
conds.
(b)
Clear the DTC stored in memory (See step 5 on page
DI–305).
(c)
Turn the ignition switch to LOCK, and wait at least for 20
seconds.
(d)
Turn the ignition switch to ON, and wait at least for 20 se-
conds.
(e)
Check the DTC (See page DI–305).
OK:
DTC B1140/32 is not output.
HINT:
Codes other than code B1140/32 may be output at this time, but
they are not relevant to this check.
NG
Go to step 9.
OK
From the results of the above inspection, the malfunctioning part can now be considered normal.
To make sure of this, use the simulation method to check.
