Engine |
A |
SAE Code: P08D2 |
MONITOR DESCRIPTION
This DTC indicates a short to ground in the shift solenoid valve SC2 circuit. If there is a short to ground in the shift solenoid valve SC2 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.

[*1]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- Stop the vehicle.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P08D411.
-
Check the DTC judgment result.
