DTC U1113: EV Remote CAN timeout
 
 
caution
  • If DTC U1113 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 EV remote-ECU cannot be received, the KOS-ECU stores DTC U1113.
 
 
TROUBLESHOOTING HINTS
  • Malfunction of CAN bus line
  • Malfunction of EV remote-ECU
  • Malfunction of KOS-ECU
 
 
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 power supply mode of the electric motor switch to the OFF before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect scan tool (M.U.T.-IIISE) ."
(2) Turn the power supply mode of the electric motor switch to ON.
(3) Diagnose the CAN bus line.
(4) Turn the power supply mode of 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 other system diagnostic trouble code.
Check if the DTC is set in the EV remote-ECU.
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the power supply mode of the electric motor switch to the OFF before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect scan tool (M.U.T.-IIISE) ."
(2) Erase the DTC.
(3) Turn the power supply mode of the electric motor switch to ON.
(4) Check if DTC is set.
(5) Turn the power supply mode of the electric motor switch to OFF.
Is the DTC set?
Perform troubleshooting for the EV remote-ECU (Refer to GROUP 54A, MITSUBISHI remote control - Diagnosis ).
Go to Step 3.
 
STEP 3. Using scan tool (M.U.T.-IIISE), read the other system diagnostic trouble code.
Check if the DTC U1113 is set in the combination meter.
(1)
cautionTo prevent damage to scan tool (M.U.T.-IIISE), always turn the power supply mode of the electric motor switch to the OFF before connecting or disconnecting scan tool (M.U.T.-IIISE).
Connect scan tool (M.U.T.-IIISE). Refer to "How to connect scan tool (M.U.T.-IIISE) ."
(2) Turn the power supply mode of the electric motor switch to ON.
(3) Check if DTC is set.
(4) Turn the power supply mode of 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 KOS-ECU.
(1) Erase the DTC.
(2) Turn the power supply mode of the electric motor switch from OFF to ON.
(3) Check if DTC is set.
(4) Turn the power supply mode of the electric motor switch from ON to OFF.
Is the DTC set?
Replace the EV remote-ECU (Refer to GROUP 54A, MITSUBISHI remote control - EV remote-ECU ).
A poor connection, open circuit or other intermittent malfunction is present in the CAN bus lines between the EV remote-ECU and the KOS-ECU (Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
 
STEP 5. Recheck for diagnostic trouble code.
Check again if the DTC is set in the KOS-ECU.
(1) Erase the DTC.
(2) Turn the power supply mode of the electric motor switch from OFF to ON.
(3) Check if DTC is set.
(4) Turn the power supply mode of the electric motor switch from ON to OFF.
Is the DTC set?
Replace KOS-ECU and register the ID codes (Refer to ).
A poor connection, open circuit or other intermittent malfunction is present in the CAN bus lines between the EV remote-ECU and the KOS-ECU (Refer to GROUP 00, How to Use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunctions ).
