According to current from the ECM, the shift solenoid valve SLP controls primary pulley pressure in accordance with the requested gear ratio to perform gear ratio changes.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P28247F | Pressure Control Solenoid "J" Actuator Stuck Off | Any of the following conditions are met (1-trip detection logic):
·
When the oil pressure sensor output value is 0.4 MPa (4.1 kgf/cm2, 58 psi) or more and the target gear ratio is less than 1.0, the actual gear ratio is 2.0 or more for 2 seconds or more. ·
When the oil pressure sensor output value is 0.4 MPa (4.1 kgf/cm2, 58 psi) or more and the target gear ratio is 2.0 or more, the actual gear ratio is less than 0.5 for 1.5 seconds or more. |

This DTC is stored when either of the above detection patterns is met.
The ECM compares the actual gear ratio with the target gear ratio. When the actual gear ratio and target gear ratio are different, the ECM detects the malfunction, illuminates the MIL and stores this DTC.
When performing the confirmation driving pattern, obey all speed limits and traffic laws.
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.
Connect the GTS to the DLC3.
Turn the ignition switch to ON and turn the GTS on.
Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
Turn the ignition switch off and wait for 2 minutes or more.
Turn the ignition switch to ON and turn the GTS on.
Start the engine.
Perform the D Position Shift Test inspection in Road Test. [*1]
[*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 / Transmission / Utility / All Readiness.
Input the DTC: P28247F.
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 |
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.
Perform the universal trip to clear permanent DTCs.
Perform initialization when parts related to the continuously variable transaxle system are replaced.
Check that no DTCs are stored after performing initialization.
Connect the GTS to the DLC3.
Turn the ignition switch to ON.
Turn the GTS on.
Enter the following menus: Powertrain / Transmission / Trouble Codes.
Read the DTCs using the GTS.
If any DTCs other than P28247F are output, perform troubleshooting for those DTCs first.
| Result | Proceed to |
