7 CHECK AIR BAG SENSOR REAR RH
(a) Connect the connector to the airbag sensor assy center.
(b) Interchange the airbag sensor rear LH with RH and con-
nect the connectors to them.
(c) Connect the negative (-) terminal cable to the battery,
and wait for at least 2 seconds.
(d) Turn the ignition switch to the ON position, and wait for at
least 60 seconds.
(e) Clear the DTCs stored in memory (see page 05-1215).

DTC B1155/39 AIRBAG SENSOR REAR (LH)
MALFUNCTION
CIRCUIT DESCRIPTION
The airbag sensor rear LH consists of the safing sensor, the diagnostic circuit and the lateral deceleration
sensor, etc.
If the airbag sensor assy center receives signals from the lateral deceleration sensor, it judges whether or
not the SRS should be activated.
DTC B1155/39 is recorded when a malfunction in the airbag sensor rear LH is detected.
