Comes on Engine A SAE Code:
P08DC

MONITOR DESCRIPTION

This DTC indicates a short to +B or open in the shift solenoid valve SC3 circuit. If there is a short to +B or open in the shift solenoid valve SC3 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>K121F (CVT)>CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM>DTC CHECK / CLEAR



1.

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

2.

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

3.

Perform the D Position Shift Test inspection in 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.


4.

Stop the vehicle.

5.

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

6.

Input the DTC: P08DD15.

7.

Check the DTC judgment result.
