SYSTEM CALIBRATION
| CAUTION | If a trouble occurs during the system calibration resulting in stopping the process or interrupting sensor data read, the DTC 28 {Adjustment / Inspection halt} of occupant detection system will be detected to illuminate the airbag warning light. In this case, perform the system calibration again, or perform the system calibration again after repairing the trouble cause. Compartment temperature during the system calibration must be within 0 to 40°C. Perform the system adjusting after installing the seat to vehicle, when replace the occupant detection system or remove the passenger's seat. |
