Inspection Procedure 4: The remote climate control is impossible (wireless LAN communication is normal).
 
 
cautionBefore replacing the ECU, ensure that the power supply circuit, the ground circuit and the communication circuit are normal.
 
 
TECHNICAL DESCRIPTION (COMMENT)
If the remote climate control has not been activated (although the wireless LAN communication is normal), the remote climate control is not programmed by your customer or the EV remote-ECU is defective.
 
 
TROUBLESHOOTING HINTS
  • Remote climate control is not programmed by your customer.
  • The EV remote-ECU may be defective
 
 
DIAGNOSIS
STEP 1. Using scan tool (M.U.T.-IIISE), check the DTC.
(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) Check if DTC is set in the EV remote-ECU.
Is the DTC set?
Troubleshoot the EV remote-ECU (Refer to ).
Go to Step 2.
 
STEP 2. Using scan tool (M.U.T.-IIISE), check the data list.
Program a remote climate control by using the wireless LAN device. Then check the service data which is stored in the EV remote-ECU (Refer to ).
