SYMPTOM PROCEDURES
SIMPLIFIED WIRING SYSTEM (SWS)54B-288
STEP 28. Check licence plate lamp connector F-06 for
loose, corroded or damaged terminals, or terminals
pushed back in the connector.
Q: Is licence plate lamp connector F-06 in good condition?
YES : Go to Step 29.
NO : Repair or replace the damaged component(s). Refer
to GROUP 00E, Harness Connector Inspection
P.00E-2. Check that the licence plate lamps
illuminate normally.
STEP 29. Check the licence plate lamp bulbs.
(1) Remove the licence plate lamp bulbs.
(2) Verify that both licence plate lamp bulbs are not damaged
or burned out.
Q: Are both licence plate lamp bulbs in good condition?
YES : Go to Step 30.
NO : Replace the licence plate lamp bulbs. Verify that the
licence plate lamps illuminate normally.
STEP 30. Check the ground circuit to the licence plate
lamp. Measure the resistance at licence plate lamp
connector F-06.
(1) Disconnect licence plate lamp connector F-06 and measure
the resistance available at the wiring harness side of the
connector.
(2) Measure the resistance value between terminal 1 and
ground.
The resistance should be 2 ohms or less.
Q: Is the measured resistance 2 ohms or less?
YES : Go to Step 32.
NO : Go to Step 31.

FLASHER TIMER
GENERAL DESCRIPTION CONCERNING THE FLASHER TIMERM1549023600238
Refer to circuit diagrams GROUP-90
Refer to configuration diagrams GROUP-80The following ECUs affect the functions and control
of the flasher timer.
FLASHER TIMER FUNCTION
.
TURN-SIGNAL LAMP
The turn-signal lamp output (flashing signal) is turned ON when
the ignition switch is ON and the turn-signal lamp switch is ON
(LH or RH). If the front turn-signal lamp or rear turn-signal lamp
bulb has burned out, the flashing speed increases to indicate
that the bulb has burned out.
NOTE: If LH or RH side turn signal lamp bulbs have burned
out, the flashing speed will remain the same.
.
TURN-SIGNAL INDICATORS
At the same time that the turn-signal lamps are illuminated, the
ETACS-ECU sends a signal to illuminate the turn-signal lamp
indicator via the CAN bus line. The combination meter receives
the transmitted signal and turns the turn-signal lamp indicator
on and off.
.
HAZARD WARNING LAMP
Detects the signal where the hazard warning lamp switch input
changes from OFF to ON, and reverse the flashing state
according to this signal. The hazard warning lamps toggle on
and off whenever the hazard warning lamp switch is operated.
NOTE: The hazard warning lamp switch is a push-return type
toggle switch. FUNCTION CONTROL ECU
