(4) Engine stop
When the START button is pressed at the vehicle speed of 3 km/h or less, the SKM turns off the IGN
relay to stop the engine.
When the vehicle speed is 3 km/h or more or no speed signal is input, the SKM performs the
following functions: 1.
2.
When the START switch is pressed for 3 sec. or more at more than 3 km/h, the ignition status is
changed from IGN to ACC.
If the switch is pressed again, the ignition status is changed from ACC to IGN.
When the START switch is pressed for 3 sec. or more with no vehicle speed signal (CAN signal
timeout, abnormal signal), the ignition status is changed from IGN to ACC. If the switch is pressed
again, the ignition status is changed from ACC to OFF. -
-
When the START button is pressed and held with IGN ON, the ignition status is changed to OFF.
When the START button is pressed briefly, the ignition status is changed to ACC ON. 3.
(5) ACC ON/Power OFF
The SKM changes the ignition status to OFF from ACC ON when:
the engine START/STOP button is pressed with the brake pedal released after the ignition status is
changed from IGN ON to ACC ON.
the REKES LOCK or passive LOCK is operated with ACC ON.
the BCM sends the driver's door open signal.
12 minutes have passed with ACC ON. 1.

4.Except brake switch signal input
For the vehicles with A/T, when the START switch is pressed for 10 sec. or more, the ignition
status is changed to IGN ON and the engine start request signal is sent regardless of the brake
signal, provided that the initial ignition status is ACC ON and the gear selector lever is in P or N
position. *-

8) SKM Warning Control
(1) Smart key not found warning (Key out warning)
If no verified smart key is identified as being in the vehicle with IGN ON or ACC ON, the SKM sends the
signal, which identifies that there is no verified key inside the vehicle, to the BCM and instrument cluster
through the BCAN (Smart key not found warning). This warning continues for up to 10 sec. until the
warning condition is deactivated.
The SKM stops the warning immediately after the warning condition is deactivated.

The SKM starts to identify a smart key by using the interior antenna after confirming that all the
doors are closed through CAN communication.
If no smart key is found it sends the signal for [Smart key not found warning].
* No cyclic smart key searching after transmission
If a smart key is found, no operation is performed.
- Smart key not found warning deactivation conditions
If below conditions are met, the SKM sends the signal for [Smart key not found warning]
to deactivate the warning.

The SKM starts to identify a smart key by using the interior antenna if the [Smart key not found
warning] signal is not output.
a. If no smart key is found it sends the signal for [Smart key not found warning].
b. If a smart key is found, no operation is performed.
The SKM searches for a smart key inside the vehicle at 3 sec. intervals while the [Smart key not

(1) Rear glass/outside mirror heated wire switch
Overview ▶
The rear glass/outside mirror heated wire is operated by BCM.
The heated wire operates for about 12 minutes when the switch is pressed with the engine started.
Press the switch again to stop the operation.
The output is "ON" only for 6 minutes when turning on the rear defogger switch within 10 minutes after
completion of output for 12 minutes. This can be done only once.
This function is available only when the engine is running.

When the AUTO washer switch is operated with IGN ON and the INT/AUTO switch OFF, the
washer motor is operated for 2 sec. and the wiper continues to cycle 4 times. And then the washer
motor is operated for 2 sec. and the wiper continues to cycle 3 times before returning to park
position.
The auto washer switch signal is overridden during speed sensitive intermittent wiper, washer
coupled wiper or auto washer coupled wiper operation.
When turning the wiper switch to AUTO position during the operation of auto washer, the auto
washer stops its operation and the intermittent/automatic wiping mode will be started.
The front and rear washer switch signal are overridden during the operation of auto washer.
The input from the switch during the AUTO washer coupled wiper operation also is ignored. 1.

If pressing the switch when the wiper switch turns
to the "OFF" position, washer fluid is sprayed
once and wiper operates 4 times.
After a while, washer fluid is sprayed once more
and the wiper operates 3 times.

2) Basic Theory of ABS Function
To give you a better understanding of the tasks and functions of ABS, we will first look at the physics
principles.
(1) Stopping distance
The stopping distance depends on the vehicle weight and initial speed when braking starts. This also
applies for vehicle with ABS, where ABS always tries to set an optimum brake force on each wheel. As
great forces are exerted between the tires and the carriageway when braking, even with ABS the wheels
may scream and rubber is left on the road. With an ABS skid mark one may be able to clearly recognize
the tire profile. The skid mark of an ABS vehicle does not however leave any hint of the speed of the
vehicle in the case of an accident, as it can only be clearly drawn at the start of braking.
(2) Brake force on a wheel
The maximum possible brake force on a wheel depends on the wheel load and the adhesion coefficient
between tire and carriageway. With a low adhesion coefficient the brake force, which can be obtained is
very low. You are bound to know the result already from driving on winter roads. With a high adhesion
coefficient on a dry road, the brake force, which can be obtained, is considerably higher. The brake
force, which can be obtained, can be calculated from below formula:
Maximum brake force ▶
FBmax = wheel load FR x coefficient of frictionMh
The braking process cannot be described sufficiently
accurately with the brake forces calculated. The
values calculated only apply if the wheel is not locked.
In the case of a locking wheel, the static friction turns
into lower sliding friction, with the result that the
stopping distance is increased. This loss of friction is
termed "slip" in specialist literature.
