P1212 TCS COMMUNICATION LINE
P1212 TCS COMMUNICATION LINE
Description
INFOID:0000000009267244
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.

DTC DETECTION LOGIC
NOTE:
• If DTC P1212 is displayed with DTC U1001, first perform the trouble diagnosis for DTC U1001. Refer
• If DTC P1212 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer
Freeze frame data is not stored in the ECM for this self-diagnosis.

DTC DETECTION LOGIC
NOTE:
• If DTC P1217 is displayed with DTC UXXXX, first perform the trouble diagnosis for DTC UXXXX.
• If DTC P1217 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer
.
If the cooling fan or another component in the cooling system malfunctions, engine coolant temperature will
rise.
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to
. Also, replace the engine oil. Refer to
.
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-13, "Anti-Freeze Coolant Mixture Ratio"
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
DTC CONFIRMATION PROCEDURE
1.
PERFORM COMPONENT FUNCTION CHECK
Perform component function check. Refer to
EC-361, "Component Function Check"
.
NOTE:
Use component function check to check the overall function of the cooling fan. During this check, a DTC might
not be confirmed.
Is the inspection result normal?
YES
>> INSPECTION END
NO
>> Go to
Component Function Check
INFOID:0000000009267248
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.
DTC No.

(Overheat)
• Cooling fan does not operate properly
(Overheat).
• Cooling fan system does not operate
properly (Overheat).
• Engine coolant was not added to the
system using the proper filling method.
• Engine coolant is not within the specified
range.
• Harness or connectors
(The cooling fan circuit is open or shorted.)

P1217 ENGINE OVER TEMPERATURE
Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
Is the coolant level in the reservoir tank and/or radiator below the
proper range?
YES
>> Go to
NO
>> GO TO 2
2.
PERFORM COMPONENT FUNCTION CHECK-II
Confirm whether customer filled the coolant or not.
Did customer fill the coolant?
YES
>> Go to
NO
>> GO TO 3.
3.
PERFORM COMPONENT FUNCTION CHECK-III
With CONSULT
1. Turn ignition switch ON.
2. Perform “COOLING FAN” in “ACTIVE TEST” mode with CONSULT and touch “LOW” on the CONSULT
screen.
