Trouble in Passenger Airbag ON / OFF Indicator

Transcription

1 8 SUPPLEMENTAL RESTRAINT SYSTEM OCCUPANT CLASSIFICATION SYSTEM Trouble in Passenger Airbag ON / OFF Indicator DESCRIPTION The occupant classification system detects the front passenger seat condition and then indicates whether the front passenger airbag is activated or not through the passenger airbag ON/OFF indicator illumination. The passenger airbag ON/OFF indicator illumination changes depending on the front passenger seat condition as shown in the table below. Front passenger seat condition ON Indicator OFF Indicator Adult is seated ON OFF Child is seated OFF ON Vacant OFF OFF Occupant classification system failure OFF ON

Go to step 9 CHECK PASSEER AIRBAG ON/OFF INDICATOR CONDITION Check if the passenger airbag ON/OFF indicator correctly indicates the front passenger seat condition. Front passenger seat condition ON Indicator OFF Indicator Adult is seated ON OFF Child is seated OFF ON Vacant OFF OFF Occupant classification system failure OFF ON PERFORM ZERO POINT CALIBRATION Connect the intelligent tester to the DLC. Using the intelligent tester, perform the zero point calibration (See page -46). : COMPLETED is displayed. Go to step 5 4 PERFORM SENSITIVITY CHECK Using the intelligent tester, perform the sensitivity check (See page -46). () Confirm that nothing is placed on the passenger seat. () Confirm that the beginning sensor reading is within the standard range.

(4) Confirm that the sensitivity is within the standard range. 7 to kg (59.5 to 7.75 lb) When performing the sensitivity check, use a solid metal weight (the check result may not be accurate if a liquid weight is used). Go to step 5 5 RETIGHTEN FRONT SEAT ASSEMBLY RH BOLT Loosen the 4 installation bolts of the front seat assembly RH. Tighten the 4 installation bolts of the front seat assembly RH to the specified torque. Torque: 7 N*m (80 kgf*cm, 7 ft.*lbf) 6 PERFORM ZERO POINT CALIBRATION Connect the intelligent tester to the DLC. Using the intelligent tester, perform the zero point calibration (See page -46). : COMPLETED is displayed. Go to step 8 7 PERFORM SENSITIVITY CHECK Using the intelligent tester, perform the sensitivity check (See page -46). () Confirm that nothing is placed on the passenger seat. () Confirm that the beginning sensor reading is within the standard range.

(4) Confirm that the sensitivity is within the standard range. 7 to kg (59.5 to 7.75 lb) When performing the sensitivity check, use a solid metal weight (the check result may not be accurate if a liquid weight is used). Go to step 8 8 CHECK CONNECTO (e) Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds. Check that the connectors are properly connected to the occupant classification ECU and the 4 occupant classification sensors. : The connectors are properly connected. Disconnect the connectors from the occupant classification ECU and the 4 occupant classification sensors. Check that the connectors are not damaged or deformed. : The connectors are normal. REPAIR OR REPLACE WIRE HARNESS AND CONNECTOR 9 CHECK DTC (e) Connect the connectors to the occupant classification ECU and the 4 occupant classification sensors. Connect the negative (-) terminal cable to the battery. Turn the ignition switch to the on position, and wait for at least 60 seconds. Clear the DTCs stored in the memory (See page - 54).

Check the DTCs (See page -54). : DTC is not output. REPLACE CENTER AIRBAG SENSOR ASSEMBLY 0 REPLACE OCCUPANT CLASSIFICATION ECU Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds. Replace the occupant classification ECU (See page - 4). Perform the inspection using parts from a normal vehicle if possible. PERFORM ZERO POINT CALIBRATION Connect the negative (-) terminal cable to the battery. Connect the intelligent tester to the DLC. Using the intelligent tester, perform the zero point calibration (See page -46). : COMPLETED is displayed. Go to step PERFORM SENSITIVITY CHECK Using the intelligent tester, perform the sensitivity check (See page -46). () Confirm that nothing is placed on the passenger seat.
