DTC P1211 TCS CONTROL UNITPFP:47850
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.
On Board Diagnosis LogicNBS000D7

Freeze frame data is not stored in the ECM for this self-diagnosis.

The MIL will not light up for this self-diagnosis.
DTC Confirmation ProcedureNBS000D8
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
WITH CONSULT-III
1. Start engine and let it idle for at least 60 seconds.
2. Check 1st trip DTC.

DTC P1212 TCS COMMUNICATION LINEPFP:47850
DescriptionNBS000DA
NOTE:

If DTC P1212 is displayed with DTC U1000 or U1001, first perform the trouble diagnosis for DTC
U1000, U1001. Refer to EC-151, "
DTC U1000, U1001 CAN COMMUNICATION LINE" .

If DTC P1212 is displayed with DTC U1010, first perform the trouble diagnosis for DTC U1010.
Refer to EC-154, "
DTC U1010 CAN COMMUNICATION" .
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and VDC/TCS/ABS control unit (with VDC models) or “ABS actuator
and electric unit (control unit)” (without VDC models).
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].
