• Brake force control function at braking hard detects driver ′s brake operations with the pressure sensor,
judges a brake booster ′s maximum brake power function by using information from the vacuum sensor, and
enhances more powerful braking force by controlling brakes of four wheels.
• VDC warning lamp blinks while VDC function is in operat ion and indicates to the driver that the function is in
operation.
• CONSULT can be used to diagnose the system.
• Fail-safe function is adopted. When a malfunction occurs in VDC function, the control is suspended for VDC
function and TCS function. However, ABS function and EBD function operate normally. Refer to BRC-39,
"Fail-safe".
INPUT SIGNAL AND OUTPUT SIGNAL
Major signal transmission between each unit via communication lines is shown in the following table.
OPERATION CHARACTERISTICS
VDC Function That Prevents Oversteer Tendency
• During cornering, brake force (brake fluid pressure) is applied on front wheel and rear wheel on the outer
side of turn. Momentum is generated directing the vehicle toward the outer side of the turn. Oversteer is pre-
vented.
• Changing driving lane on a slippery road, when there may be a tendency to oversteer, engine output is con-
trolled as well as brake force (brake fluid pr essure) of 4 wheels. Oversteer tendency decreases.

Exhaust Valve Timing Control Solenoid ValveINFOID:0000000012431286
Exhaust valve timing control solenoi
d valve is activated by ON/OFF
pulse duty (ratio) signals from the ECM.
The exhaust valve timing control solenoid valve changes the oil
amount and direction of flow through exhaust valve timing control
unit or stops oil flow.
The longer pulse width retards valve angle.
The shorter pulse width advances valve angle.
When ON and OFF pulse widths become equal, the solenoid valve
stops oil pressure flow to fix the exhaust valve angle at the control
position.
Fuel InjectorINFOID:0000000012431287
The fuel injector is a small, precise solenoid valve. When the ECM
supplies a ground to the fuel injector circuit, the coil in the fuel injec-
tor is energized. The energized coil pulls the ball valve back and
allows fuel to flow through the fuel injector into the intake manifold.
The amount of fuel injected depends upon the injection pulse dura-
tion. Pulse duration is the length of time the fuel injector remains
open. The ECM controls the injection pulse duration based on
engine fuel needs.
Fuel PumpINFOID:0000000012431288
*: ECM determines the start signal status by the signals of engine speed and battery voltage.
The ECM activates the fuel pump for a few seconds after the ignition switch is turned ON to improve engine
start ability. If the ECM receives a engine speed signal from the crankshaft position sensor (POS) and cam-
shaft position sensor (PHASE), it knows that the engi ne is rotating, and causes the pump to operate. If the
engine speed signal is not received when the ignition s witch is ON, the engine stalls. The ECM stops pump
operation and prevents battery discharging, thereby improving safety. The EC M does not directly drive the fuel
pump. It controls the ON/OFF fuel pump rela y, which in turn controls the fuel pump.

DIAGNOSIS SYSTEM (ECM)
OK: Self-diagnosis is carried out and the result is OK.
NG: Self-diagnosis is carried out and the result is NG.
—: Self-diagnosis is not carried out.
When all SRT related self-diagnoses show OK result
s in a single cycle (Ignition OFF-ON-OFF), the SRT will
indicate “CMPLT”. → Case 1 above
When all SRT related self-diagnoses show OK results through several different cycles, the SRT will indicate
“CMPLT” at the time the respective se lf-diagnoses have at least one OK result. → Case 2 above
If one or more SRT related self-diagnoses show NG resu lts in 2 consecutive cycles, the SRT will also indicate
“CMPLT”. → Case 3 above
The table above shows that the minimum number of cycl es for setting SRT as “INCMP” is the number one (1)
for each self-diagnosis (Case 1 & 2) or the number tw o (2) for one of self-diagnoses (Case 3). However, in
preparation for the state emissions inspection, it is unnecessary for each self-diagnosis to be executed twice
(Case 3) for the following reasons:
• The SRT will indicate “CMPLT” at the time the respective self-diagnoses have one (1) OK result.
• The emissions inspection requires “CMPLT” of the SRT only with OK self-diagnosis results.
• During SRT driving pattern, the 1st trip DTC (NG) is detected prior to “CMPLT” of SRT and the self-diagnosis memory must be erased from the ECM after repair.
• If the 1st trip DTC is erased, all the SRT will indicate “INCMP”. NOTE:
SRT can be set as “CMPLT” together with the DTC(s). Therefore, DTC check must always be carried out
prior to the state emission inspection even though the SRT indicates “CMPLT”.
DIAGNOSIS DESCRIPTION : Permanent Diagno stic Trouble Code (Permanent DTC)
INFOID:0000000012431338
Permanent DTC is defined in SAE J1979/ISO 15031-5 Service $0A.
ECM stores a DTC issuing a command of turning on MIL as a permanent DTC and keeps storing the DTC as
a permanent DTC until ECM judges that there is no presence of malfunction.
Permanent DTCs cannot be erased by using the Erase function of CONSULT or Generic Scan Tool (GST) and
by disconnecting the battery to shut off power to ECM. This prevents a vehicle from passing the state emission
inspection without repairing a malfunctioning part.
When not passing the state emission inspection due to more than one permanent DTC, permanent DTCs
should be erased, referring to this manual.
NOTE:
• The important items in state emission inspection are t hat MIL is not ON, SRT test items are set, and perma-
nent DTCs are not included.
• Permanent DTCs do not apply for regions that permanent DTCs are not regulated by law.

DAYTIME RUNNING LIGHT SYSTEM
DAYTIME RUNNING LIGHT SYSTEM : System DiagramINFOID:0000000012432771
DAYTIME RUNNING LIGHT SYST EM : System DescriptionINFOID:0000000012432772
The headlamp system is equipped with a daytime running light control that activates the high beam head-
lamps at approximately half illumination whenever the e ngine is operating. If the parking brake is applied
before the engine is started the daytime running lights will not be illuminated. The daytime running lights will
illuminate once the parking brake is released. Thereaf ter, the daytime running lights will continue to operate
when the parking brake is applied.
OPERATION
The BCM monitors inputs from the parking brake swit ch and the combination switch (lighting and turn signal
switch) to determine when to activate the daytime running light system. The BCM sends a daytime running
light request to the IPDM E/R via the CAN communication lines. The IPDM E/R grounds the daytime running
light relay 1 which in turn, provides power to the LH high beam lamp. Power flows through the LH high beam
lamp to the RH high beam lamp. The high beam lamps are wired in series which causes them to illuminate at
a reduced intensity. When daytime light relay 2 is open, it prevents headlamp low beam from turning on while
daytime running lights are operating.
