TURN SIGNAL AND HA ZARD WARNING LAMPS

System DescriptionINFOID:0000000005146625
TURN SIGNAL OPERATION
When the combination switch (lighting and turn signal switch) is in LH or RH position with the ignition switch in
ON position, the BCM detects the TURN RH or TURN LH ON request. The BCM outputs the flasher signal to
the respective turn signal lamp. The BCM also sends a turn indicator signal ON request via the CAN commu-
nication lines to the combination meter. The combination meter then activates the appropriate turn signal indi-
cator and audible buzzer.
HAZARD LAMP OPERATION
When the hazard switch is in ON position, the BCM detects the hazard switch signal ON. The BCM outputs the
flasher signal (right and left). The BCM sends a hazar d indicator signal ON request via the CAN communica-
tion lines to the combination meter. The combinati on meter then activates the hazard indicator and audible
buzzer.
REMOTE KEYLESS ENTRY OPERATION
The remote keyless entry receiver transmits a hazard request signal to the BCM, then BCM controls hazard
lamps.
Refer to SEC-10, "

TURN SIGNAL LAMP CIRCUIT
TURN SIGNAL LAMP CIRCUIT
DescriptionINFOID:0000000005146654
The BCM monitors inputs from the combination switch (lighting and turn signal switch) to determine when to
activate the turn signals. The BCM outputs voltage direction to the left and right turn signals during turn signal
operation or both during hazard warning operation. The BCM sends a turn signal indicator request to the com-
bination meter via the CAN communication lines.
The BCM performs the fast flasher operation (fail-safe) if any bulb or harness of the turn signal lamp circuit is
open.
NOTE:
Turn signal lamp blinks at normal speed when using the hazard warning lamp.
Component Function CheckINFOID:0000000005146655
1.CHECK TURN SIGNAL LAMP
CONSULT-III
1. Select "FLASHER" of BCM (FLASHER) active test item.
2. With operating the test items, check that the turn signal lamp blinks.
Does the turn signal lamp blink?
YES >> Turn signal lamp circuit is normal.
NO >> Refer to EXL-44, "
Diagnosis Procedure".
Diagnosis ProcedureINFOID:0000000005146656
Regarding Wiring Diagram information, refer to EXL-77, "Wiring Diagram".
1.CHECK TURN SIGNAL LAMP BULB
Check the applicable lamp bulb to be sure the proper bulb standard is in use and the bulb is not open.
Is the bulb OK?
YES >> GO TO 2.
NO >> Replace the bulb.
2.CHECK TURN SIGNAL LAMP OUTPUT VOLTAGE
1. Turn the ignition switch OFF.
2. Disconnect the front turn/fog lamp connector or the rear combi- nation lamp connector.
3. Turn the ignition switch ON.
4. With turn signal switch operating, check the voltage between the BCM harness connector M20 and ground.LH : Turn signal lamp LH blinking
RH : Turn signal lamp RH blinking
Off : The turn signal lamp OFF

CAN COMM CIRC
[U1000] Malfunction is detected in CAN communication.
CAUTION:
Even when there is no ma
lfunction on CAN communication system, malfunction may be
misinterpreted when battery has low voltag e (when maintaining 7 - 8 V for about 2 sec-
onds) or 10A fuse [No. 3, located in the fuse block (J/B)] is disconnected. MWI-26
VEHICLE SPEED
CIRC
[B2205]Malfunction is detected when an erroneous speed signal is input.
CAUTION:
Even when there is no malfunction on speed signal system, malfunction may be misin-
terpreted when battery has low voltage (whe
n maintaining 7 - 8 V for about 2 seconds). MWI-27
