HINT:

This DTC is stored when any of the above detection patterns are met.


MONITOR DESCRIPTION

When the ignition switch is off and current is detected as flowing to the solenoid valve during a solenoid current cut request, the ECM illuminates the MIL and stores a DTC.

CONFIRMATION DRIVING PATTERN

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.


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.

6.

Turn the GTS on.

7.

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

8.

Input the DTC: P17029F.

9.

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 Confirmation Driving Pattern and check the DTC judgment result again.
