Inspection Procedure
- PERFORM ZERO POINT CALIBRATION
- Connect the Techstream to the DLC3.
- Turn the power switch ON (IG).
- Using the Techstream, perform the zero point calibration (see INITIALIZATION
).
OK: "Zero Point Calibration is complete." is displayed.
NG: Go to step 4
OK: Go to next step.
- PERFORM SENSITIVITY CHECK
- Using the Techstream, perform the sensitivity check (see INITIALIZATION
).
Standard value: 27 to 33 kg (59.52 to 72.75 lb)
NG: Go to step 4
- Using the Techstream, perform the sensitivity check (see INITIALIZATION
).
- CHECK FOR DTC
- Turn the power switch ON (IG).
- Clear the DTCs (see DTC CHECK / CLEAR
).
HINT:
First clear DTCs stored in the occupant classification ECU and then in the center airbag sensor.
- Turn the power switch OFF.
- Turn the power switch ON (IG).
- Check the DTCs (see DTC CHECK / CLEAR
).
OK: DTC B1788 is not output.
HINT:
DTCs 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 power switch OFF.
- Disconnect the cable from the negative (-) battery terminal, and wait for at least 90 seconds.
- Replace the front seat RH (see REMOVAL
).
HINT:
Perform the inspection using parts from a normal vehicle if possible.
- PERFORM ZERO POINT CALIBRATION
- Connect the cable to the negative (-) battery terminal, and wait for at least 2 seconds.
- Connect the Techstream to the DLC3.
- Turn the power switch ON (IG).
- Using the Techstream, perform the zero point calibration (see INITIALIZATION
).
OK: "Zero Point Calibration is complete." is displayed.
NG: Go to step 8
OK: Go to next step.
