20. REPLACE CERTIFICATION ECU (SMART KEY ECU ASSEMBLY)

(a) Temporarily replace the certification ECU (smart key ECU assembly) with a new one.

HINT
* For replacement, Removal.
* For registration, Engine Immobilizer System.

NEXT -- Continue to next step.

21. CHECK WIRELESS DOOR LOCK CONTROL SYSTEM

(a) Check that the wireless door lock functions operate normally Operation Check.

OK:

Wireless door lock functions operate normally.

NG -- REPLACE MAIN BODY ECU (MULTIPLEX NETWORK BODY ECU) Removal

OK -- END (CERTIFICATION ECU (SMART KEY ECU ASSEMBLY) WAS DEFECTIVE)

22. CHECK WAVE ENVIRONMENT

(a) Bring the electrical key transmitter sub-assembly that was checked first near the door control receiver and select the failed channel (the channel in which the buzzer did not sound) to recheck the key diagnostic mode Operation Check.

HINT
* When the electrical key transmitter sub-assembly is brought near the door control receiver, the possibility of wave interference decreases, and it can be determined if wave interference is causing the problem symptom.
* If the inspection result is that the problem only occurs in certain locations or at certain times of day, the possibility of wave interference is high. Also, added vehicle components may cause wave interference. If installed, remove them and perform the operation check.
* There may be wave interference if the vehicle is near broadcasting antennas, large video displays, wireless garage door opener systems, wireless security cameras, home security systems, etc. In this case, move the vehicle to a different location and check if there is any improvement.
* If a tool for checking electric waves, such as a signal strength meter, is available, move around the area while observing both the LF band (used by the vehicle antenna to form the detection area) and RF band (used by the electrical key transmitter sub-assembly for transmission) to check for locations where there is wave interference.

OK:

Wireless door lock buzzer sounds.

NG -- CHECK ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY

OK -- AFFECTED BY WAVE INTERFERENCE

23. CHECK ELECTRICAL KEY TRANSMITTER SUB-ASSEMBLY

(a) Check if there are any other registered electrical key transmitter sub-assemblies.
