Code No.U0245: AND CAN Time-out
 
 
caution
  • If diagnostic trouble code No. U0245 is set, be sure to diagnose the CAN bus line.
  • When replacing the ECU, always check that the communication circuit is normal.
 
 
DIAGNOSTIC FUNCTION
If the signal from smartphone link display audio cannot be received, the power liftgate control unit sets DTC No. U0245.
 
 
JUDGMENT CRITERIA
With the statuses that the electric motor switch is at ON position, system voltage is 10 to 16 V (data from ETACS-ECU), and there is no malfunction to the power supply fuse, or odometer value is 80.5 km or more, if the communication with smartphone link display audio cannot be established for 2,500 ms or more, the power liftgate control unit determines that a problem has occurred.
 
 
PROBABLE CAUSES
  • Malfunction of smartphone link display audio
  • Malfunction of the power liftgate control unit
  • Malfunction of CAN bus line
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), diagnose the CAN bus line.
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the electric motor switch to the OFF position before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect the scan tool (M.U.T.-IIISE) ."
(2) Turn the electric motor switch to ON.
(3) Diagnose the CAN bus line.
(4) Turn the electric motor switch to OFF.
Is the CAN bus line found to be normal?
Go to Step 2.
Repair the CAN bus line. (Refer to GROUP 54C, Diagnosis ).
 
STEP 2. Using scan tool (M.U.T.-IIISE), read the smartphone link display audio diagnostic trouble code
Check if DTC is set in the smartphone link display audio.
Is the DTC set?
Diagnose the smartphone link display audio. (Refer to GROUP 54A - Diagnostic Trouble Code Chart ).
Go to Step 3.
 
STEP 3. Using scan tool (M.U.T.-IIISE), read the other system diagnostic trouble code.
Check if DTC No. U0245 is set in the KOS-ECU, OSS-ECU, combination meter, ETACS-ECU or A/C-ECU.
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the electric motor switch to the OFF position before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect the scan tool (M.U.T.-IIISE) ."
(2) Erase the DTC.
(3) Turn the electric motor switch to ON.
(4) Check if DTC is set.
(5) Turn the electric motor switch to OFF.
Is the DTC set?
Go to Step 4.
Go to Step 5.
 
STEP 4. Recheck for diagnostic trouble code.
Check again if the DTC is set in the power liftgate control unit.
(1) Erase the DTC.
(2) Turn the electric motor switch to the ON position.
(3) Check if DTC is set.
(4) Turn the electric motor switch to the OFF position.
Is the DTC set?
Replace the MMCS or smartphone link display audio.
Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
 
STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set in the power liftgate control unit.
(1) Erase the DTC.
(2) Turn the electric motor switch from OFF to ON.
(3) Check if DTC is set.
(4) Turn the electric motor switch from ON to OFF.
Is the DTC set?
Replace the power liftgate control unit.
Intermittent malfunction is suspected (Refer to GROUP 00 - How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
