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
.
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.
2. Drive the vehicle and accelerate 3 consecutive seconds or more with the engine speed 1,500 rpm or
more.
3. Check “Self-diagnostic result” of “ENGINE”.
Is the DTC detected?
YES
>> Proceed to
EC-1077, "Diagnosis Procedure"
.
NO-1 >> To check malfunction symptom before repair: Refer to
GI-45, "Intermittent Incident"
NO-2 >> Confirmation after repair: INSPECTION END
Diagnosis Procedure
INFOID:0000000012198595
NOTE:
Turning the ignition switch ON with FRP sensor harness connector disconnected causes ECM to
detect DTC P119C. Be sure to erase the DTC when the diagnosis procedure.

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.
