Perform the master cylinder pressure sensor calibration to store the calibrated value
in the ASC-ECU. At the same time, the calibrated value of cut valve and inlet valve are stored.
|
|
This diagnosis code is set when the calibrated values for cut valve and inlet valve stored
in ASC-ECU are not within the predetermined range.
|
|
- ASC-ECU malfunction
- Noise interference
|
|
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.
|
|
|
|
Perform calibration of brake fluid pressure sensor calibration (Refer to ).
|
|
Q.
Has the calibration succeeded?
|
|
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ),
and then go to Step 4.
|
|
|
|
Erase the diagnosis code.
|
|
Q.
Is diagnosis code C2002 set?
|
|
Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
Then go to Step 4.
|
|
|
|
The procedure is complete.
|
|
|
|
Erase the diagnosis code.
