ASC-ECU receives signal from the combination meter via the CAN bus lines.
|
|
When the signal from the combination meter shows rejection, ASC-ECU determines that the
malfunction has occurred and sets this diagnosis.
|
|
- Malfunction of combination meter assembly
- Malfunction of ASC-ECU
|
|
Use the 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 the diagnosis code No. U1128 set?
|
|
This diagnosis is complete.
|
|
|
|
Check if a diagnosis code is set in the combination meter.
|
|
Q.
Is the diagnosis code set?
|
|
Diagnose the combination meter. Then go to Step 5.
|
|
|
|
Check if the diagnosis code other than code No. U1128 is set from ASC-ECU.
|
|
Q.
Is the diagnosis code other than code No. U1128 set?
|
|
Troubleshoot for the relevant diagnosis code (Refer to ).
|
|
|
|
Replace the combination meter (Refer to GROUP 54A - combination meter

Replace the hydraulic unit (integrated with ASC-ECU) (Refer to ).
Then go to Step 6.
|
|
|
|
Intermittent malfunction (Refer to GROUP 00 - How to Use Troubleshooting/How
to Cope with Intermittent Malfunctions ).
|
|
|
|
(1)Erase the diagnosis code.
|
|
(2)Turn the electric motor switch from "LOCK" (OFF) position to "ON" position.
