ON-BOARD DIAGNOSYS SYSTEM OUTLINE (KEYLESS ENTRY SYSTEM)
EHU091469000106
Special Features
• The keyless entry system has an on-board diagnostic function to facilitate system diagnosis.
• The on-board diagnostic function consists of the following functions: a malfunction detection function, which
detects overall malfunctions in the keyless entry system-related parts; a memory function, which stores
detected DTCs; a display function, which indicates system malfunctions by DTC display; and a PID/data
monitoring function, which reads out specific input/output signals.
• Using the WDS or equivalent, DTCs can be read out and cleared, and the PID/data monitoring function can be
activated.

On-board Diagnostic Function
Malfunction detection function
• Detects overall malfunctions in the keyless entry system-related parts.
Display function
• If any malfunction is detected, the keyless warning light (red) in the instrument cluster illuminates to inform the
driver of a system malfunction.
Memory function
• Stores malfunctions in the keyless entry system-related parts detected by the malfunction detection function,
and the stored malfunction contents are not cleared even if the ignition switch is turned to the LOCK position or
the negative battery cable is disconnected.

PID/data monitor function
• The PID/data monitor function is used for optionally selecting input/output signal monitor items preset in the
keyless control module and reading them out in real-time.
• Use the WDS or equivalent to read the PID/data monitor.

CARD KEY (TRANSMITTER) CONSTRUCTION/OPERATION
EHU091469000108
•
A card-type transmitter that is thin and convenient to carry has been adopted.
•
A maximum of six transmitters can be programmed for one vehicle.
•
A built-in operation indicator light illuminates according to LOCK/UNLOCK button operation and request signal
from the vehicle.
•
In case the transmitter is inoperable due to battery depletion, the doors can be locked/unlocked and the engine
can be started using the auxiliary key.
•
A transponder is built into the auxiliary key for vehicles with the immobilizer system.
End Of Sie
KEYLESS ANTENNA CONSTRUCTION/OPERATION
EHU091469000109
•
Consists of the antennas for request signal output (7 locations).
•
Operated by the keyless control module, the keyless antennas send request signals to produce the reception
areas inside and outside the vehicle.
•
The keyless antennas built-into the front doors can output signals to both inside or outside the vehicle, and
change the level of the radiowave (output to inside or outside the vehicle) according to operation conditions.
•
The keyless control module locates the card key by determining the antenna which is receiving the signal the
strongest.
