P1211 TCS CONTROL UNIT
P1211 TCS CONTROL UNIT
Description
INFOID:0000000006158807
The malfunction information related to TCS is transferred through the CAN communication line from “ABS
actuator and electric unit (control unit)” to ECM.
Be sure to erase the malfunction information such as DTC not only for “ABS actuator and electric unit
(control unit)” but also for ECM after TCS related repair.
On Board Diagnosis Logic
INFOID:0000000006158808
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 Procedure
INFOID:0000000006158809
TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.
1. Start engine and let it idle for at least 60 seconds.
2. Check 1st trip DTC.
3. If 1st trip DTC is detected, go to

P1212 TCS COMMUNICATION LINE
Description
INFOID:0000000006158811
NOTE:
• If DTC P1212 is displayed with DTC U0101 or U1001, first perform the trouble diagnosis for DTC
U0101, U1001. Refer to
• If DTC P1212 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer
.
This CAN communication line is used to control the smooth engine operation during the TCS operation. Pulse
signals are exchanged between ECM and “ABS actuator and electric unit (control unit)”.
Be sure to erase the malfunction information such as DTC not only for “ABS actuator and electric unit
(control unit)” but also for ECM after TCS related repair.
