MONITOR DESCRIPTION

This DTC indicates an open or short in the shift solenoid valve SLU circuit. If there is an open or short in the shift solenoid valve SLU circuit, the ECM detects the malfunction, illuminates the MIL and stores this DTC.

CONFIRMATION DRIVING PATTERN

CAUTION:

When performing the confirmation driving pattern, obey all speed limits and traffic laws.


HINT:
·

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

·

When clearing the permanent DTCs, refer to the Clear Permanent DTC procedure.

Click hereDrivetrain>K313 (CVT)>CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM>DTC CHECK / CLEAR



1.

Connect the GTS to the DLC3.

2.

Turn the ignition switch to ON and turn the GTS on.

3.

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

4.

Turn the ignition switch off and wait for 2 minutes or more.

5.

Turn the ignition switch to ON and turn the GTS on.

6.

Start the engine.

7.

Drive the vehicle and confirm the lock-up on and off conditions according to Road Test. [*1]

HINT:

[*1]: Normal judgment procedure.

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


8.

Stop the vehicle.

9.

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

10.

Input the DTC: P275613.

11.

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


N/A
·

Unable to perform DTC judgment

·

Number of DTCs which do not fulfill DTC preconditions has reached ECU memory limit



HINT:
·

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

·

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

·

If the judgment result shows INCOMPLETE or N/A, perform the normal judgment procedure again.
