PEDAL VIBRATION OR ABS OPERATION SOUND OCCURS
Diagnosis ProcedureINFOID:0000000003772628
CAUTION:
Under the following conditions, ABS is activated an d vibration is felt when brake pedal is lightly
depressed. However, this is normal.
• When shifting gears
• When driving on slippery road
• During cornering at high speed
• When passing over bumps or grooves [at approximately 50 mm (1.97 in) or more]
• When pulling away just after starting engine [at approximately 10 km/h (6 MPH) or higher]
1.SYMPTOM CHECK 1
Check that there are pedal vibrat ions when the engine is started.
Do vibrations occur?
YES >> GO TO 2
NO >> Inspect the brake pedal.
2.SYMPTOM CHECK 2
Check that there are ABS operation noises when the engine is started.
Do the operation noises occur?
YES >> GO TO 3
NO >> Perform self -diagnosis. Refer to BRC-24, "
CONSULT-III Function (ABS)".
3.SYMPTOM CHECK 3
Check symptoms when electrical component (headlamps, etc.) switches are operated.
Do symptoms occur?
YES >> Check if there is a radio, antenna, antenna lead wire, or wiring close to the control unit. If there is,
move it farther away.
NO >> Normal

< FUNCTION DIAGNOSIS >[WITH INTELLIGENT KEY SYSTEM]
DOOR LOCK FUNCTION
• To ensure the Intelligent Key works effectively, us
e within 80 cm range of each doors, however the operable
range may differ according to surroundings.
SELECTIVE UNLOCK FUNCTION
When a LOCK signal is transmitted from Intelligent Key, all doors will be locked.
When an UNLOCK signal is transmitted from Inte lligent Key once, driver's door will be unlocked.
Then, if an UNLOCK signal is transmitted from Intell igent Key again within 5 seconds, all other doors will be
unlocked.
When a liftgate signal is transmitted from Intelligent Key for more than 0.5 second, the back door operates to
the full open position. After opening, another signal will cause the back door to close.
HAZARD AND HORN REMINDER FUNCTION
When doors are locked or unlocked by Intelligent Key, BCM flashes hazard warning lamps as a reminder and
sends horn chirp signal to IPDM E/R. IPDM E/R sounds horn as a reminder.
The hazard and horn reminder has a horn chirp mode (C mode) and a non-horn chirp mode (S mode).
Operating function of hazard and horn reminder
Hazard and horn reminders do not operate if any door switch is ON (any door is OPEN).
How to change hazard and horn reminder mode
With CONSULT-III
Refer to DLK-56, "
CONSULT-III Function (INTELLIGENT KEY)".
Without CONSULT-III
Refer to Owner's Manual for instructions.
AUTO DOOR LOCK FUNCTION
Auto Door Lock Function
When all doors are locked, ignition switch is OFF (ignition switch is not pressed) and key switch is OFF, doors
are unlocked with Intelligent Key button. When BCM does not receive the following signals within 30 seconds,
all doors are locked.
• Door switch is ON (door is opened)
• Door is locked
• Ignition switch is ON
• Key switch is ON (mechanical key is inserted in ignition key cylinder)
Auto door lock mode can be changed by DOOR LOCK -UNLOCK SET mode in “WORK SUPPORT”. Refer to
DLK-52, "
DOOR LOCK : CONSULT-III Function (BCM - DOOR LOCK)".
PANIC ALARM FUNCTION
When ignition switch is OFF (ignition switch is not pr essed) and key switch is OFF, BCM receives PANIC
ALARM signal from Intelligent Key through the remote keyless entry receiver and the Intelligent Key unit.
BCM turns on and off headlamp intermittently and transmits theft warning horn signal to IPDM E/R. Then,
IPDM E/R turns on and off horn intermittently.
The headlamp flashes and the horn sounds intermittently.
The alarm automatically turns off:
• After 25 seconds
• When BCM receives any signal from Intelligent Key
Panic alarm function mode can be changed by PANIC ALARM SET mode in “WORK SUPPORT”. Refer to
DLK-56, "
CONSULT-III Function (INTELLIGENT KEY)".
KEYLESS POWER WINDOW DOWN (OPEN) FUNCTION
Front power windows (with left and right front power window anti-pinch system) open when the unlock button
on Intelligent Key is activated and kept pressed for more than 3 seconds with the ignition switch OFF. The win-
dows keep opening if the unlock button is continuously pressed.
The power window opening stops when the following operations are performed:
• When the unlock button is kept pressed more than 15 seconds.
• When the ignition switch is turned ON while the power window opening is operated.
• When the unlock button is released.
