Tucson AWD L4-2.4L (2010)
(1) To provide an audible feedback to the driver when flasher is active, a Flasher Sound Relay is controlled.
(2) While Flasher Lamp is operated, at the time of Output On/Off transition, the Flasher Sound Relay is activated.
(3) Flasher Sound Relay is controlled by the BCM.
2. Turn signal and hazard control
(1) Turn Left/ Right Signal Flashing Function
A. If the Left (or Right) turn switch is active and if IGN2 is On, the left (or Right) turn signal outputs are driven.
B. The turn signal is active as long as both conditions ((TurnSigLHSW or TurnSigRHSW=On) and IGN2=On) are true and is turned Off
when one of these conditions is no longer detected.
C. If a failure is detected (Bulb/LED) outage or open load on the activated turn signal side, the flasher frequency is doubled.
D. This failure can be detected when IGN1 and IGN2 On (IGN1=On and IGN2=On).
E. While Turn switch is On and failure was detected, even if bulb (or LED) failure is no longer detected, keep the double blinking flashing
and after next Turn switch On transition, only then, flasher is activated with normal blinking.
(2) Lane Change Turn Left/ Right Signal Control Function
A. Flasher lane-change feature means that a momentary activation of the turn switch will cause 3 flashes on the indicator circuit.
B. This lane-change feature operates under the following conditions:
-
Lane change mode enabled
-
Ignition 2 shall be On, the lane change feature is not available if Ignition 2 is Off.
-
The "bulb-fail" mode is not working and the flashing frequency is always Normal Blinking in Lane Change mode (85±10period/min).
-
During the Lane Change mode operation, if the user moves the turn switch in the other direction, then Lane change mode is finished and
the other direction's flashing (Normal or Lane change flashing) will start depending on the switch detection time.
