Accuracy Check Of Occupant Classification Sensor

CAUTION: The following precaution must be observed when executing accuracy testing and calibration.

Perform the occupant classification sensor calibration at room temperature. (Proposal: 20 ± 15°C (68 ± 27°F)) (Before the calibration, place the occupant classification sensor more than 30 minutes at room temperature.)
Do not apply any load or vibration while the weight check and the calibration is performed.
Perform the weight check and the calibration after seat components are all assembled.

CAUTION: To prevent damage to scan tool MB991958, always turn the ignition switch to the "LOCK" (OFF) position before connecting or disconnecting scan tool MB991958.
