ENTRY AND START SYSTEM(for Entry Function) Room Oscillator does not Recognize Key

DTC Code DTC Name
Room Oscillator does not Recognize Key

DESCRIPTION

If code verification cannot be performed in the vehicle interior, there may be problems with the communication between the vehicle (indoor electrical key antenna assembly (center pillar RH), (center pillar LH) or (rear floor)*) and electrical key transmitter sub-assembly, or the certification ECU (smart key ECU assembly) may be malfunctioning. When the electrical key transmitter sub-assembly is brought into the vehicle, verification of the key ID code transmitted from the electrical key transmitter sub-assembly and the key ID code stored in the certification ECU (smart key ECU assembly) is performed. If verification cannot be performed or the codes do not match, the engine switch cannot be turned on (IG) and the engine cannot be started.

When a door is unlocked and the electrical key transmitter sub-assembly is brought into the vehicle, the certification ECU (smart key ECU assembly) activates the indoor electrical key antenna assembly which transmits radio waves to detect the electrical key transmitter sub-assembly. If the electrical key transmitter sub-assembly recognizes that it is in the detection area, it responds with the key ID code. This information is received by the indoor electrical key antenna assembly and then sent to the certification ECU (smart key ECU assembly).

CAUTION / NOTICE / HINT

Note:

  • The entry and start system (for Entry Function) uses the LIN communication system and CAN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the entry and start system (for Entry Function) after confirming that the communication systems are functioning properly.

    Click here

  • 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(CAN). 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.

  • Before replacing the certification ECU (smart key ECU assembly), refer to entry and start system (for Entry Function) Precaution.

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

  • The indoor electrical key antenna assemblies have an antenna coil between each pair of CLG and ANTE.

PROCEDURE

  1. CHECK ENTRY AND START SYSTEM (VEHICLE INTERIOR DETECTION)

    1. Get into the vehicle while carrying a different, previously-registered electrical key transmitter sub-assembly.

    2. Move the shift lever to N.*1

    3. Depress the brake pedal*1 or clutch pedal*2.

    4. Check that the smart warning light in the combination meter assembly illuminates (green), and then press the engine switch and check that the engine starts.

      • *1: for Multi-Mode Manual Transaxle

      • *2: for Manual Transaxle

    3. When operating the engine switch, check whether the engine starts.

      Tip:

      • If the electrical key transmitter sub-assembly cannot be verified even though it is inside the detection area, the engine start check can be performed by removing the transmitter battery from the electrical key transmitter sub-assembly and holding the electrical key transmitter sub-assembly near the engine switch.

      • If the engine cannot be started when performing this inspection, the certification ECU (smart key ECU assembly), ID code box (immobiliser code ECU)* or steering lock ECU (steering lock actuator assembly) may be malfunctioning.

    1. Install the transmitter battery to the electrical key transmitter sub-assembly.

      Click here

    2. Bring the electrical key transmitter sub-assembly near the No. 2 indoor electrical key antenna assembly (center pillar RH) and perform an engine start check.

      Click here

      Note:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 2 indoor electrical key antenna assembly (center pillar RH).

    3. Bring the electrical key transmitter sub-assembly near the No. 2 indoor electrical key antenna assembly (center pillar LH) and perform an engine start check.

      Click here

      Note:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 2 indoor electrical key antenna assembly (center pillar LH).

    4. Bring the electrical key transmitter sub-assembly near the No. 1 indoor electrical key antenna assembly (front floor) and perform an engine start check.

      Click here

      Note:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (front floor).

    5. Bring the electrical key transmitter sub-assembly near the No. 1 indoor electrical key antenna assembly (rear floor) and perform an engine start check. (for 3 Door)

      Click here

      Note:

      Communication may not be possible if the electrical key transmitter sub-assembly is within 0.2 m (0.656 ft.) of the No. 1 indoor electrical key antenna assembly (rear floor).

    Tip:

    • 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 problem only occurs in specific places or at specific times, wave interference may be the cause of the problem. Also, added vehicle components may cause 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 radio 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.

      Tip:

      • If the buzzer sounds, it can be determined that the vehicle interior transmitters are operating normally.

      • It is possible to check which indoor electrical key antenna assembly (center pillar RH, center pillar LH, front floor or rear floor) is operating by the sounding of the buzzer.

      • If the buzzer does not sound for any indoor electrical key antenna assembly, the certification ECU (smart key ECU assembly) circuit may be malfunctioning.
