STEP 7. M.U.T.-III data list
Check the following data list. (Refer to

P.23C-254

).

• Item No.8: Steering angle sensor

• Item No.21: Wheel speed sensor <FL>

• Item No.22: Wheel speed sensor <FR>

• Item No.23: Wheel speed sensor <RL>

• Item No.24: Wheel speed sensor <RR>

• Item No.25: Yaw rate sensor

• Item No.26: Lateral G sensor

Q: Is the check result normal?

YES : Go to Step 8.
NO : Perform the troubleshooting for the ASC. (Refer to

GROUP 35C

− Troubleshooting

P.35C-18

). Then go

to Step 9.

STEP 8. Retest the system.
Q: Is the check result normal?

YES : Intermittent malfunction. (Refer to GROUP 00

− How

to Cope with Intermittent Malfunction

P.00-15

).

NO : Replace the AWC-ECU. (Refer to

P.23C-295

). Then

go to Step 9.

STEP 9. Retest the system.
Q: Is the check result normal?

YES : This diagnosis is complete.
NO : Return to Step 1.
