P1212 TCS COMMUNICATION LINE

Description

INFOID:0000000003388130

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.

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, always replace the coolant. Refer to

CO-8, "Draining"

. Also, replace

the engine oil. Refer to

LU-8, "Draining"

Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Always use
coolant with the proper mixture ratio. Refer to

MA-16, "FOR NORTH AMERICA : Anti-Freeze Cool-

ant Mixture Ratio"

After refilling coolant, run engine to ensure that no water-flow noise is emitted.

DTC CONFIRMATION PROCEDURE

PERFORM COMPONENT FUNCTION CHECK

Perform component function check. Refer to

EC-355, "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.

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.
