DTC P1128 THROTTLE CONTROL MOTOR

DTC P1128 THROTTLE CONTROL MOTORPFP:16119
Component DescriptionEBS01110
The throttle control motor is operated by the ECM and it opens and closes the throttle valve.
The current opening angle of the throttle valve is detected by the throttle position sensor and it provides feed-
back to the ECM to control the throttle control motor to make the throttle valve opening angle properly in
response to driving condition.
On Board Diagnosis LogicEBS01111
This self-diagnosis has the one trip detection logic.
FAIL-SAFE MODE
When the malfunction is detected, the ECM enters fail-safe mode and the MI lights up.
DTC Confirmation ProcedureEBS01112
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.
WITH CONSULT-II
1. Turn ignition switch ON and wait at least 2 seconds.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for 5 seconds.
4. If DTC is detected, go to EC-695, "
Diagnostic Procedure" .
WITHOUT CONSULT-II

DTC P1211 TCS CONTROL UNIT

DTC P1211 TCS CONTROL UNITPFP:47850
DescriptionEBS01117
The malfunction information related to TCS is transferred through the CAN communication line from ESP/
TCS/ABS control unit to ECM.
Be sure to erase the malfunction information such as DTC not only for ESP/TCS/ABS control unit but
also for ECM after TCS related repair.
On Board Diagnosis LogicEBS01118
Freeze frame data is not stored in the ECM for this self-diagnosis. The MI will not light up for this self-
diagnosis.
DTC Confirmation ProcedureEBS01119
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 60 seconds.
4. If 1st trip DTC is detected, go to EC-698, "

DTC P1212 TCS COMMUNICATION LINEPFP:47850
DescriptionEBS0111B
NOTE:
If DTC P1212 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC U1000,
U1001. Refer to EC-579, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and ESP/TCS/ABS control unit.
Be sure to erase the malfunction information such as DTC not only for ESP/TCS/ABS control unit but
also for ECM after TCS related repair.
On Board Diagnosis LogicEBS0111C
Freeze frame data is not stored in the ECM for this self-diagnosis. The MI will not light up for this self-
diagnosis.
DTC Confirmation ProcedureEBS0111D
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-II
1. Turn ignition switch ON.
2. Select “DATA MONITOR” mode with CONSULT-II.
3. Start engine and let it idle for at least 10 seconds.
4. If a 1st trip DTC is detected, go to EC-699, "
Diagnostic Proce-
dure" .
WITHOUT CONSULT-II
1. Start engine and let it idle for at least 60 seconds.
2. Turn ignition switch OFF, wait at least 10 seconds and then turn ON.
3. Perform Diagnostic Test Mode II (Self-diganostic results) with ECM.
4. If 1st trip DTC is detected, go to EC-699, "

COOLING FAN CONTROL
*1: This signal is sent to ECM through CAN communication line.
*2: ECM determines the start signal status by the signals of engine speed and battery voltage.
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].
The ECM sends a cooling fan control signal to the smart entrance control unit through CAN communication
line, and the smart entrance control unit controls cooling fan relays.
