When the M.U.T.-III is operated, the ASC-ECU will learn the neutral position of the G
sensor and then store it in its memory.
|
|
The ASC-ECU will store this diagnosis code when it has not learned the neutral position
of the G sensor.
|
|
- The neutral position of the G sensor has not been learned.
- ASC-ECU malfunction
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|
Q.
Is the check result normal?
|
|
Repair the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
On completion, go to Step 2.
|
|
|
|
Q.
Is diagnosis code No.C1392 or C1393 set?
|
|
This diagnosis is complete.
|
|
|
|
Use the M.U.T.-III to check whether the G sensor-related diagnosis code is set or not.
|
|
Q.
Is the diagnosis code set?
|
|
Troubleshoot for the relevant diagnosis code (Refer to ).
|
|
|
|
Check whether the ASC-ECU is installed correctly. Refer to .
|
|
Q.
Is the check result normal?
|
|
Execute "Lateral G sensor calibration" and "G sensor calibration" on "Special
function". After the calibration is performed (Refer to )
, turn the ignition switch from "OFF" to "ON".Then go to Step 5.
|
|
|
|
Install the ASC-ECU properly, and execute "Lateral G sensor calibration" and "G
sensor calibration" on "Special function". After the calibration is performed (Refer to )
, turn the ignition switch from "OFF" to "ON".Then go to Step 5.
|
|
|
|
Check the following data list (Refer to ).
|
|
- Item 08: Lateral G sensor
- Item 09: G sensor
- Item 73: Lateral G sensor offset
- Item 96: G sensor offset
|
|
Q.
Is the check result normal?
|
|
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ),
and then go to Step 7.
