P1212 TCS COMMUNICATION LINE
DescriptionINFOID:0000000009462746
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 malf unction information such as DTC not onl y for “ABS actuator and electric unit
(control unit)” but also for ECM after TCS related repair.
DTC LogicINFOID:0000000009462747
DTC DETECTION LOGIC
NOTE:
• If DTC P1212 is displayed with DTC UXXXX, first perform the tr ouble diagnosis for DTC UXXXX.
• If DTC P1212 is displayed with DT C P0607, first perform the trouble diagnosis for DTC P0607. Refer
to EC-884, "DTC Logic"
.
Freeze frame data is not stored in the ECM for this self-diagnosis.

Perform the trouble diagnosis for TCS. Refer to BRC-55, "Work Flow".
NOTE:
If DTC P1212 is displayed with DTC UXXXX and/ or P0607, perform the following trouble diagnosis.
• Trouble diagnosis for DTC UXXXX Refer to EC-630, "DTC Index"
.
• Trouble diagnosis for DTC P0607 Refer to EC-884, "DTC Logic"
.
DTC No. Trouble diagnosis name DTC detecting condition Possible cause
P1212 TCS communication line ECM cannot receive the information from

to EC-884, "DTC Logic"
.
If the cooling fan or another component in the coo ling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnorma lly high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be su re to replace the coolant. Refer to CO-35, "System Inspection"
.
Also, replace the engine oil. Refer to MA-27, "ENGINE OIL : Changing Engine Oil"
.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-12, "FOR USA AND CANADA : Engine Cool-
ant Mixture Ratio".
2. After refilling coolant, run engine to en sure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to EC-892, "Component Function Check"
.
NOTE:
Use component function check to check the overall functi on of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES >> INSPECTION END
NO >> Proceed to EC-893, "Diagnosis Procedure"
.
Component Function CheckINFOID:0000000009462750
1.PERFORM COMPONENT FUNCTION CHECK-I
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by turning it a quarter turn to allow built-up
pressure to escape. Then turn the cap all the way off.
