Resistance: Below 1 Ω H01010 H01059 H01051 () (+) H01167 Repair or replace harness or connector between side airbag sensor assembly (LH) and airbag sensor assembly. 523
DI354 6 Check wire harness (to ground). Side (LH) For the connector (on the airbag sensor assembly side) between the side airbag sensor assembly (LH) and the airbag sensor assembly, measure the resistance between body ground and each of SSL, and. Resistance: 1 MΩ or Higher SSL (+) () H01008 H01052 H01168 Repair or replace harness or connector between side airbag sensor assembly (LH) and airbag sensor assembly. 7 Check wire harness (to B+). Side (LH) (a) Turn ignition switch to. (b) For the connector (on the airbag sensor assembly side) between the side airbag sensor assembly (LH) and the airbag sensor assembly, measure the voltage between body ground and each of SSL,, and. Voltage: 0 V SSL H01008 AB0119 H01053 (+) () H08271 Repair or replace harness or connector between side airbag sensor assembly (LH) and airbag sensor assembly. 524
DI355 8 Is DTC B1141/33 output again? Side (LH) CG DLC3 H01007 AB0119 H10600 H01066 Tc DTC B1141/33 H12865 PREPARATI: (a) Connect the connector to the side airbag sensor assembly (LH). (b) Connect the connector to the airbag sensor assembly. (c) Connect negative () terminal cable to the battery, and wait at least for 2 seconds. (a) Turn ignition switch to and wait at least for 20 seconds. (b) Clear DTC stored in memory (See step 5 on page DI239 ). (c) Turn ignition switch to LOCK, and wait at least for 20 seconds. (d) Turn ignition switch to and wait at least for 20 seconds. (e) Check DTC (See page DI239 ). DTC B1141/33 is not output. HINT: Codes other than code B1141/33 may be output at this time, but they are not relevant to this check. NO Go to step 9. YES 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. 525
DI356 9 Check airbag sensor assembly. Side (RH) CG H01007 AB0119 H10600 H01066 DLC3 Tc DTC B1141/33 H12866 PREPARATI: (a) Turn ignition switch to LOCK. (b) Disconnect negative () terminal cable from the battery, and wait at least for 90 seconds. (c) Disconnect the side airbag sensor (LH) from the connector and connect the side airbag sensor (RH) to the connector. (d) Connect negative () terminal cable to the battery, and wait at least for 2 seconds. (a) Turn ignition switch to and wait at least for 20 seconds. (b) Clear DTC stored in memory (See step 5 on page DI239 ). (c) Turn ignition switch to LOCK, and wait at least for 20 seconds. (d) Turn ignition switch to and wait at least for 20 seconds. (e) Check DTC (See page DI239 ). DTC B1141/33 is not output. HINT: Codes other than code B1141/33 may be output at this time, but they are not relevant to this check. Replace airbag sensor assembly. 526
