ACCURACY CHECK OF OCCUPANT 
CLASSIFICATION SENSOR

M1524025100016

CAUTION

The following precaution must be observed when execut-
ing accuracy testing and calibration.

• Eliminate the occupant classification sensor friction.
• Perform the occupant classification sensor calibration 

at room temperature. (Proposal: 20 

± 15°C (68 ± 27° F)) 

(Before the calibration, place the occupant classifica-
tion sensor more than 30 minutes at room tempera-
ture.)

• 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 con-
necting or disconnecting scan tool MB991958.
1. Connect scan tool MB991958 to the data link connector.

2. Open and close the front door (RH) 5 times hardly to remove 

the friction. And if the door does not open and close 
smoothly after the impact, hit the front and rear sides of 
seatback about eight times each to remove the friction. 

3. To execute accuracy check and calibration, operate scan 

tool MB991958 (MUT-III Sub Assembly) as follows.

(1) Select "Interactive Diagnosis".
(2) Select "Special Function".
(3) Select "Seat Weight Sensor Accuracy Check".

the front end, and put the 30 kg (66 pounds) weight on 
the center of the seat cushion. Then, carry out the friction 
removal in step (2) and press the OK button to execute 
accuracy check.
NOTE: If there is not the 30 kg (66 pounds) weight, load a 
square thing of 30 to 40 kg (66 to 88 pounds) instead of 
the weight. At this time, operate the arrow button of 
weight input part on MUT-III to input the loaded weight
