Code No.U1190 No receive fault detect signal
 
 
caution
  • Before replacing the ECU, ensure that the power supply circuit, the earth circuit and the communication circuit are normal.
 
 
JUDGEMENT CRITERIA
ETACS-ECU sends the diagnosis code (U code) detection permission or prohibition signal to each ECU connected to the CAN bus line. If the combination meter cannot receive the diagnosis code (U code) detection permission or prohibition signal for 5 seconds after turning the ignition switch to ON position, diagnosis code U1190 will be set.
 
 
PROBABLE CAUSES
  • Malfunction of the ETACS-ECU
  • Malfunction of CAN bus line
 
 
DIAGNOSIS PROCEDURE
STEP 1. M.U.T.-IIISE CAN bus diagnostics
Use the M.U.T.-IIISE to diagnose the CAN bus lines.
Is the check result normal?
Go to Step 2.
Repair the CAN bus line (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. M.U.T.-IIISE other system diagnosis code
Check if diagnosis code is set in the ETACS-ECU.
Is the diagnosis code set?
Diagnose the ETACS-ECU (Refer to ).
Go to Step 3.
 
STEP 3. M.U.T.-IIISE other system diagnosis code
Check if a diagnosis code, which relates to CAN communication-linked systems below, is set.
  • KOS-ECU
    • Code No.U1190: No receive fault detect signal
Is the diagnosis code set?
Go to Step 4.
Go to Step 5.
 
STEP 4. Check whether the diagnosis code is set again.
Recheck if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) On completion, check that the diagnosis code is not set again.
Is the diagnosis code set?
Replace ETACS-ECU.
A poor connection, open circuit or other intermittent malfunction is present in the CAN bus lines between the ETACS-ECU and the combination meter (Refer to GROUP 00 - How to use troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 5. Check whether the diagnosis code is set again.
Recheck if the diagnosis code is set.
(1) Erase the diagnosis code.
(2) Turn the ignition switch to "ON" position.
(3) On completion, check that the diagnosis code is not set again.
Is the diagnosis code set?
Replace combination meter.
A poor connection, open circuit or other intermittent malfunction is present in the CAN bus lines between the ETACS-ECU and the combination meter (Refer to GROUP 00 - How to use troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
