cautionBefore replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal.
 
 
TECHNICAL DESCRIPTION (COMMENT)
When "Parking location check (headlights/taillights)" does not work, the CAN bus lines, the ETACS-ECU circuit (headlights/taillights) or the EV remote-ECU may be defective.
 
 
TROUBLESHOOTING HINTS
  • The CAN bus line may be defective
  • The circuit to the ETACS-ECU (head/tail) may be defective
  • The EV remote-ECU may be defective
 
 
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 off the power supply mode of the electric motor switch 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) Press the electric motor switch to turn on the power supply mode.
(3) Diagnose the CAN bus line.
(4) Press the electric motor switch to turn off the power supply mode.
Is the CAN bus line found to be normal?
Go to Step 2.
Repair the CAN bus lines (Refer to GROUP 54C - Troubleshooting ).
 
STEP 2. Recheck for DTC.
Check again if the DTC is set in the EV remote-ECU.
(1) Erase the DTC.
(2) Press the electric motor switch to turn the power supply mode from "OFF" to "ON."
(3) Check if DTC is set.
Is the DTC set?
Troubleshoot the EV remote-ECU (Refer to ).
Go to Step 3.
 
STEP 3. Operation check by using the lighting switch.
Check whether the headlights and the taillights work normally when the lighting switch is operated.
Is the check result normal?
The trouble can be an intermittent malfunction (Refer to GROUP 00 - How to use Troubleshooting/Inspection Service Points - How to Cope with Intermittent Malfunction ).
: Troubleshoot the headlight (Refer to ).
: Troubleshoot the rear combination light (Refer to ).
