DescriptionNBS000D6
The malfunction information related to TCS is transferred through the CAN communication line from VDC/
TCS/ABS control unit (with VDC models) or “ABS actuator and electric unit (control unit)” (without VDC mod-
els) to ECM.
Be sure to erase the malfunction information such as DTC not only for VDC/TCS/ABS control unit
(with VDC models) or “ABS actuator and electric unit (control unit)” (without VDC models) but also for
ECM after TCS related repair.

Cooling Fan Control
*1: The ECM determines the start signal status by the signals of engine speed and battery voltage.
*2: This signal is sent to ECM through CAN communication line.
The ECM controls the cooling fan corresponding to the vehicle speed, engine coolant temperature, refrigerant
pressure, and air conditioner ON signal. The control system has 3-step control [HIGH/LOW/OFF].

DTC P1225, P1234 TP SENSORPFP:16119
Component DescriptionNBS000DM
Electric throttle control actuator consists of throttle control motor,
throttle position sensor, etc. The throttle position sensor responds to
the throttle valve movement.
The throttle position sensor has two sensors. These sensors are a
kind of potentiometers which transform the throttle valve position into
output voltage, and emit the voltage signal to the ECM. In addition,
these sensors detect the opening and closing speed of the throttle
valve and feed the voltage signals to the ECM. The ECM judges the
current opening angle of the throttle valve from these signals and the
ECM controls the throttle control motor to make the throttle valve
opening angle properly in response to driving condition.
On Board Diagnosis LogicNBS000DN
The MIL will not light up for this self-diagnosis.
DTC Confirmation ProcedureNBS000DO
NOTE:
If DTC Confirmation Procedure has been previously conducted, always turn ignition switch OFF and wait at
least 10 seconds before conducting the next test.
