Inspection Procedure
- PERFORM ZERO POINT CALIBRATION
- Connect the intelligent tester to the DLC3.
- Turn the ignition switch to the on position.
- Using the intelligent tester, perform the zero point calibration (See INITIALIZATION
).
OK: COMPLETED is displayed.
NG: Go to step 4
OK: Go TO NEXT STEP
- PERFORM SENSITIVITY CHECK
- Using the intelligent tester, perform the sensitivity check (See INITIALIZATION
).
- Confirm that nothing is placed on the passenger seat.
- Confirm that the beginning sensor reading is within the standard range.
Standard range: -3.2 to 3.2 kg (-7 to 7 lb)
- Place a 30 kg (66.14 lb) weight (e.g. a lead mass) onto the front passenger seat.
- Confirm that the sensitivity is within the standard range.
Standard range: 27 to 33 kg (59.52 to 72.75 lb)
HINT:
When performing the sensitivity check, use a solid metal weight (the check result may not be accurate if a liquid weight is used).
NG: Go to step 4
OK: Go TO NEXT STEP
- Using the intelligent tester, perform the sensitivity check (See INITIALIZATION
).
- CHECK DTC
- Turn the ignition switch to the on position.
- Clear the DTCs stored in the memory (See DTC CHECK/CLEAR
).
HINT:
First clear DTCs stored in the occupant classification ECU and then in the center airbag sensor assembly.
- Turn the ignition switch to the lock position.
- Turn the ignition switch to the on position.
- Check the DTCs (See DTC CHECK/CLEAR
).
OK: DTC B1788 is not output.
HINT:
Codes other than DTC B1788 may be output at this time, but they are not related to this check.
OK: USE SIMULATION METHOD TO CHECK
NG: Go TO NEXT STEP
- REPLACE FRONT SEAT ASSEMBLY RH
- Turn the ignition switch to the lock position.
- Disconnect the negative (-) terminal cable from the battery, and wait for at least 90 seconds.
- Replace the front seat assembly RH (See REMOVAL
).
HINT:
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 DLC3.
- Turn the ignition switch to the on position.
- Using the intelligent tester, perform the zero point calibration (See INITIALIZATION
).
OK: COMPLETED is displayed.
NG: Go to step 8
OK: Go TO NEXT STEP
- PERFORM SENSITIVITY CHECK

).
- Confirm that nothing is placed on the passenger seat.
- Confirm that the beginning sensor reading is within the standard range.
Standard range: -3.2 to 3.2 kg (-7 to 7 lb)
- Place a 30 kg (66.14 lb) weight (e.g. a lead mass) onto the front passenger seat.
