P1212 TCS COMMUNICATION LINE

Description

INFOID:0000000006547126

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

to

EC-161, "DTC Logic"

.

• If DTC P1212 is displayed with DTC P0607, first perform the trouble diagnosis for DTC P0607. Refer

to

EC-304, "DTC Logic"

.

Freeze frame data is not stored in the ECM for this self-diagnosis.

DTC CONFIRMATION PROCEDURE

1.

PRECONDITIONING

If DTC Confirmation Procedure has been previously conducted, always perform the following procedure
before conducting the next test.
1.

Turn ignition switch OFF and wait at least 10 seconds.

2.

Turn ignition switch ON.

3.

Turn ignition switch OFF and wait at least 10 seconds.

TESTING CONDITION:
Before performing the following procedure, confirm that battery voltage is more than 10.5V at idle.

>> GO TO 2.

2.

PERFORM DTC CONFIRMATION PROCEDURE

1.

Start engine and let it idle for at least 10 seconds.

2.

Check 1st trip DTC.

Is 1st trip DTC detected?

YES

>> Proceed to

EC-319, "Diagnosis Procedure"

.

NO

>> INSPECTION END

Diagnosis Procedure

INFOID:0000000006547128

Perform the trouble diagnosis for TCS. Refer to

BRC-145, "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-108, "DTC Index"

.

• Trouble diagnosis for DTC P0607 Refer to

EC-304, "DTC Logic"

.

DTC No.

TCS/CIRC
(TCS communication
line)

ECM can not receive the information from
“ABS actuator and electric unit (control
unit)” continuously.

• Harness or connectors

(CAN communication line is open or shorted.)

• ABS actuator and electric unit (control unit)
• Dead (Weak) battery

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-304, "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-11, "Draining"

. Also,

replace the engine oil. Refer to

CO-12, "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-14, "Engine 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-320, "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

>> Proceed to

EC-321, "Diagnosis Procedure"

.

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.
