DTC CONFIRMATION PROCEDURE

1.

CHECK DTC PRIORITY

If DTC P119C is displayed with DTC P0190, first perform the confirmation procedure (trouble diagnosis) for

DTC P0190.
Is applicable DTC detected?

YES

>> Perform diagnosis of applicable. Refer to 

EC-919, "DTC Logic"

.

NO

>> GO TO 2.

2.

PRECONDITIONING-1

If DTC Confirmation Procedure is previously conducted, always perform the following procedure before con-

ducting 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, check that battery voltage is 9 V or more with ignition

switch ON.

• Remaining fuel amount must be 15% or more.

>> GO TO 3.

3.

PERFORM DTC CONFIRMATION PROCEDURE

1. Start the engine and warm it up until the engine coolant temperature reaches 70

°C (158°F) or more.

P1212 TCS COMMUNICATION LINE

P1212 TCS COMMUNICATION LINE

Description

INFOID:0000000012198596

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 Logic

.

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

to 

EC-1054, "DTC Logic"

.

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