                                                     Malfunction

CIRCUIT DESCRIPTION
The side airbag sensor assembly (LH) 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 B1141/33 is recorded when occurrence of a malfunction in the side airbag sensor assembly (LH) is
detected.

                                            (b) Clear DTC stored in memory (See step 5 on page
                                                  DI-239 ).
                                            (c) Turn ignition switch to LOCK, and wait at least for 20 se-
                                                  conds.
                                            (d) Turn ignition switch to ON and wait at least for 20 se-

                                            (e) Check DTC (See page DI-239 ).
                                            HINT:
       CG       Tc                          Codes other than code B1141/33 may be output at this time, but
                                            they are not relevant to this check.

                                              YES       The malfunctioning part can now be considered
                                                        normal. To make sure of this, use the simulation
                                                        method to check.


  NO



   2        Is connector of side airbag sensor assembly (LH) properly connected?
