37 -ELECTRIC POWER STEERING (EPS) > TROUBLESHOOTING > DIAGNOSIS CODE PROCEDURES > U1190 NO RECEIVE FAULT DETECT SIGNAL
Code No. U0141 ETACS CAN timeout
Code No. U1190 No receive fault detect signal
| 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
 ). - Whenever ECU is replaced, ensure that the CAN bus lines are normal.
|
OPERATION
A fault detection enabling/inhibiting signal is sent from the ETACS-ECU to the EPS-ECU.
TROUBLE JUDGEMENT
Judgement Criterion
- When the microcomputer cannot receive any fault detection enabling/inhibiting signal from the ETACS-ECU, it determines that there is a problem in the system.
Fail Safe, Back Up Function
- The EPS-ECU sets diagnosis code No. U1190.
PROBABLE CAUSES
- Malfunction of CAN bus line
- Malfunction of the ETACS-ECU
- Malfunction of the EPS-ECU
DIAGNOSIS PROCEDURE
1. M.U.T.-IIISE CAN bus diagnostics
2. Replace the ETACS-ECU (Refer to GROUP 54A - ETACS-ECU ). 3. Replace the EPS-ECU (Refer to ).
