1.2.4 Renault card check by the UCH:
a/ Card check:
When the engine is running, the UCH checks for the presence of the Renault card in the passenger compartment (if
vehicle is hands-free) or in the card-reader when a door is opened then closed. If the Renault card is not detected, a
message on the instrument panel and a buzzer warn the driver.
Command AC036 Internal aerial test is used to check the area covered by the starting aerials inside the passenger
compartment (hands-free vehicles). The card reader flashes when the card is detected.
This command allows a hands-free card to be recognised even if it does not belong to the vehicle.
b/ Low battery warning:
If the Renault card battery is faulty or flat, the change card battery message is displayed on the instrument panel
when the vehicle is started, if there have been 5 attempts to authenticate the Renault card since the battery fault.
c/ Storing information on the card:
A device allowing information relating to the vehicle to be read from the card is available.
Information available: – VIN (Vehicle Identification Number).
