P1212 TCS COMMUNICATION LINE

P1212 TCS COMMUNICATION LINE

Description

INFOID:0000000009020863

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 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

to 

EC-351, "DTC Logic"

.

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 

CO-9, "Refilling"

. Also,

replace the engine oil. Refer to 

LU-8, "Refilling"

.

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, "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-367, "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 

EC-368, "Diagnosis Procedure"

.

Component Function Check

INFOID:0000000009020867

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.
