THEFT DETERRENT / KEYLESS ENTRY  ENTRY AND START SYSTEM(for Start Function)  Power Source Mode does not Change to ON (IG and ACC)  


DESCRIPTION

When the engine switch cannot be turned on (ACC) or on (IG), there may be a malfunction in interior certification, or the ACC relay or IG relay system. If interior certification does not succeed, the certification ECU (smart key ECU assembly) may be malfunctioning, or communication may not be possible between the No. 1 indoor electrical key antenna assembly (front floor), No. 1 indoor electrical key antenna assembly (center front floor), No. 1 indoor electrical key antenna assembly (center rear floor), No. 1 indoor electrical key antenna assembly (rear LH floor) or No. 1 indoor electrical key antenna assembly (rear RH floor), the electrical key transmitter sub-assembly, and the door control receiver.

When the electrical key transmitter sub-assembly is brought into the cabin, the key ID code sent from the electrical key transmitter sub-assembly and the key ID code stored in the certification ECU (smart key ECU assembly) are certified. If these codes do not match and certification fails, the engine switch cannot be turned on (ACC) or on (IG).

When the door is unlocked and the electrical key transmitter sub-assembly is brought into the cabin, the certification ECU (smart key ECU assembly) activates the indoor electrical key antenna and forms a detection area. When the electrical key transmitter sub-assembly is recognized inside the detection area, it returns the key ID code. This is received by the door control receiver, which then sends it to the certification ECU (smart key ECU assembly).

CAUTION / NOTICE / HINT

NOTICE:
·

When using the GTS with the engine switch off, connect the GTS to the DLC3 and turn a courtesy light switch on and off at intervals of 1.5 seconds or less until communication between the GTS and the vehicle begins. Then select Model Code "KEY REGIST" under manual mode and enter the following menus: Body Electrical / Entry&Start. While using the GTS, periodically turn a courtesy light switch on and off at intervals of 1.5 seconds or less to maintain communication between the GTS and the vehicle.

·

Make sure that no DTCs are output. If any DTCs are output, proceed to Diagnostic Trouble Code Chart.

·

If the entry and start system (for Start Function) has been canceled, enable the system before performing troubleshooting.

·

Inspect the fuses of circuits related to this system before performing the following procedure.

·

Before replacing the certification ECU (smart key ECU assembly) or an electrical key transmitter sub-assembly, refer to the Service Bulletin.

Click hereVehicle Interior>THEFT DETERRENT / KEYLESS ENTRY>ENTRY AND START SYSTEM (for Start Function)>PRECAUTION

·

After completing repairs, confirm that the problem does not recur.

·

After repair, confirm that no DTCs are output by performing "DTC Output Confirmation Operation".

·

An antenna coil is connected between the terminals of the indoor electrical key antenna.

·

The door control receiver is also involved in interior certification.



HINT:
·

If interior certification does not succeed, the History of Reason for Operation may remain in the certification ECU (smart key ECU assembly).

·

If the operation history remains, refer to the history table to determine the conditions and narrow down any trouble areas.

HINT:
·

As the effect of wave interference decreases by moving the electrical key transmitter sub-assembly close to each indoor electrical key antenna assembly, it may be possible to check whether wave interference is the cause of the problem.

·

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.



OK:

The engine starts when the electrical key transmitter sub-assembly is held near each indoor electrical key antenna assembly and the engine switch is pressed with the brake pedal depressed.

Check the No. 1 indoor electrical key antenna assembly (front floor).

When the electrical key transmitter sub-assembly is at either inspection point, check that the buzzer sounds.

HINT:
·

Select either channel 1 or channel 2 and perform the key diagnostic mode inspection for each channel.

·

If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

·

It is possible to check which No. 1 indoor electrical key antenna assembly (front floor) is operating by the sounding of the buzzer.

·

When the buzzer does not sound for No. 1 indoor electrical key antenna assembly (front floor), it can be judged that the certification ECU (smart key ECU assembly), which controls the No. 1 indoor electrical key antenna assembly (front floor), is malfunctioning.

Check the No. 1 indoor electrical key antenna assembly (rear LH floor).

When the electrical key transmitter sub-assembly is at either inspection point, check that the buzzer sounds.

HINT:
·

Select either channel 1 or channel 2 and perform the key diagnostic mode inspection for each channel.

·

If the buzzer sounds with [CH1] displayed but not with [CH2], the electrical key transmitter sub-assembly cannot be detected by channel 2 due to a malfunction, such as wave interference.

·

It is possible to check which No. 1 indoor electrical key antenna assembly (rear LH floor) is operating by the sounding of the buzzer.

·

When the buzzer does not sound for No. 1 indoor electrical key antenna assembly (rear LH floor), it can be judged that the certification ECU (smart key ECU assembly), which controls the No. 1 indoor electrical key antenna assembly (rear LH floor), is malfunctioning.

Check the transmitter battery level of the electrical key transmitter sub-assembly that was checked first.

i.

Press and hold the lock switch of the electrical key transmitter sub-assembly for 5 seconds and check the number of times that the LED illuminates.

HINT:
·

The electrical key transmitter sub-assembly sends voltage information to the certification ECU (smart key ECU assembly) when it is being used. "Yes" is displayed for the Data List item "Key Low Battery" when this voltage information indicates 2.2 V or less.
