MONITOR DESCRIPTION

These DTCs are stored when a power supply malfunction, diagnostic signal malfunction or motor operation signal malfunction is detected in the cam timing control motor with EDU assembly. The cam timing control motor with EDU assembly is equipped with a self diagnostic function, which is used to send diagnostic a signal (VTM) to the ECM. If the ECM receives a VTP or VTM open or short signal, a DTC is output immediately (1 trip detection logic).

HINT:
·

After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

Click hereEngine / Hybrid System>M20C-FKS (ENGINE CONTROL)>SFI SYSTEM>DTC CHECK / CLEAR

·

When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.

Click hereEngine / Hybrid System>M20C-FKS (ENGINE CONTROL)>SFI SYSTEM>DTC CHECK / CLEAR



1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON.

3.

Turn the GTS on.

4.

Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).

5.

Turn the ignition switch off and wait for at least 30 seconds.

6.

Start the engine.

7.

Idle the engine for 10 seconds or more [A].

8.

Turn the GTS on.

9.

Enter the following menus: Powertrain / Engine / Trouble Codes [B].

10.

Read the pending DTCs.

HINT:
·

If a pending DTC is output, the system is malfunctioning.

·

If a pending DTC is not output, perform the following procedure.



11.

Enter the following menus: Powertrain / Engine / Utility / All Readiness.

12.

Input the DTC: P136411 or P136415.

13.

Check the DTC judgment result.

GTS Display Description
NORMAL
·

DTC judgment completed

·

System normal


ABNORMAL
·

DTC judgment completed

·

System abnormal


INCOMPLETE
·

DTC judgment not completed

·

Perform driving pattern after confirming DTC enabling conditions



HINT:
·

If the judgment result is NORMAL, the system is normal.

·

If the judgment result is ABNORMAL, the system has a malfunction.

·

If the judgment result is INCOMPLETE, perform steps [A] through [B] again.

·

[A] to [B]: Normal judgment procedure.

The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.

·

When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.




CAUTION / NOTICE / HINT

NOTICE:

Inspect the fuses for circuits related to this system before performing the following procedure.


HINT:

Read Freeze Frame Data using the GTS. The ECM records vehicle and driving condition information as Freeze Frame Data the moment a DTC is stored. When troubleshooting, Freeze Frame Data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
