Code No.U1195:
Variant coding not completed
| caution |
- If there is any
problem in the CAN bus lines, an incorrect diagnosis code may be set. Prior to this diagnosis,
diagnose the CAN bus lines (Refer to GROUP 54C - CAN Bus Diagnostics Table
 ).
- Before replacing the ECU, ensure that the communication circuit is normal.
- When diagnosis code U1195 is set in ABS-ECU, the diagnosis code may also be set
in ETACS-ECU. When the diagnosis code is set in ETACS-ECU, carry out the diagnosis of the diagnosis
code for ETACS-ECU first.
|
OPERATION
- ABS-ECU receives the vehicle information stored in the ETACS-ECU via CAN
bus lines.
DIAGNOSIS CODE SET CONDITIONS
This diagnosis code is set when the variant coding for ETACS-ECU has not been implemented.
PROBABLE CAUSES
- Variant coding for ETACS-ECU has not been implemented.
- Malfunction of ABS-ECU.

|
STEP 1. M.U.T.-III CAN bus diagnostics
|
|
|
Use M.U.T.-III to diagnose the CAN bus lines.
|
|
|
Q.
Is the check result normal?
|
|
|
 Go to Step 3.
|
|
|
|
|
|
 Repair the CAN bus line (Refer to GROUP 54C - CAN Bus Diagnostics Table ).
Then go to Step 2.
|
|
|
|
|
|
STEP 2. Diagnosis code recheck after resetting CAN bus lines
|
|
|
(1)Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
|
|
|
(2)Erase the diagnosis code.
|
|
|
(3)Turn the ignition switch from the "ON" position to the "LOCK" (OFF) position.
|
|
|
Q.
Is diagnosis code No.C1195 set?
|
|
|
Go to Step 3.
|
|
|
|
|
|
This diagnosis is complete.
|
|
|
|
|
|
STEP 3. M.U.T.-III other diagnosis code
|
|
|
Use M.U.T.-III to check that other diagnosis code is set in the ETACS-ECU.
|
|
|
Q.
Is other diagnosis code set?
|
|
|
Perform troubleshooting for ETACS-ECU (Refer to GROUP 54A - ETACS, Troubleshooting ). Then
go to Step 5.
|
|
|
|
|
|
Go to Step 4.
|
|
|
|
|
|
STEP 4. Check whether the diagnosis code is set again.
|
|
|
(1)Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
|
|
|
(2)Erase the diagnosis code.
|
|
|
(3)Turn the ignition switch from the "ON" position to the "LOCK" (OFF) position.
|
|
|
Replace the hydraulic unit [(integrated with ABS-ECU) Refer to ].
Then go to Step 5.
|
|
|
|
|
|
Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent
Malfunctions ).
|
|
|
|
|
|
STEP 5. Check whether the diagnosis code is set again.
|
|
|
(1)Turn the ignition switch from the "LOCK" (OFF) position to the "ON" position.
|
|
|
(2)Erase the diagnosis code.
|
|
|
(3)Turn the ignition switch from the "ON" position to the "LOCK" (OFF) position.
|
|
|
Go to Step 1.
|
|
|
|
|
|
The procedure is complete.
