STEP 3. MUT-III data list

CAUTION

Before connecting or disconnecting the MUT-III, 
turn the ignition switch to the "LOCK" (OFF) 
position.
(1) Connect the MUT-III to the 16-pin diagnosis 

connector.

(2) Turn the ignition switch to the "ON" position.
(3) Use MUT-III to read the following data list.

Item 30: Straight G sensor/Item 31: Lateral G 

sensor

• Acceleration should measure -1.7 − 1.7 G 

when the vehicle is stopped at a level surface.

• Acceleration should change within the range 

of -1.7 

− 1.7 G during running.

Item 33: Yaw late sensor

• Angular velocity should measure -75 − 75 

deg/s when the vehicle is stopped at a level 
surface.

• Angular velocity should change within the 

range of -75 

−75 deg/s during running.

Q: Is the check result normal?

YES : 

Then go to step 8.

NO : 

Go to Step 4.

STEP 4. Voltage measurement at G and yaw late 
sensor connector C-117.

(1) Disconnect the G and yaw late sensor connector 

C-117, and measure at the harness side 
connector.

(2) Turn the ignition switch to the "ON" position.
(3) Measure the voltage between terminal 1 and 

body earth. 

OK: System voltage

Q: Is the check result normal?

YES : 

Go to Step 6.
