DTC Advanced Diagnostics: P2715
DTC P2715:Pressure Control Solenoid "D" Stuck On

General Description

The CVT lock-up clutch control solenoid valve controls hydraulic pressure to the torque converter clutch. The CVT lock-up clutch control solenoid valve is controlled by duty cycle output. The spool in the CVT lock-up clutch control solenoid valve moves the valve according to the current, and produces hydraulic pressure in proportion to the current. To supply proper torque converter clutch hydraulic pressure, the transmission control module (TCM) outputs a CVT lock-up clutch control solenoid valve hydraulic pressure control signal. If the torque converter clutch is judged as stuck ON, the TCM detects a CVT lock-up clutch control solenoid valve stuck ON malfunction and stores a DTC.

Malfunction Threshold
Symptom 2 occurs after Symptom 1 occurs.
Symptom 1: Actual torque converter slip rate [ETR] is more than 99 %, or less than 130 % for at least 0.6 second when target torque converter slip rate is less than 97 %.
Symptom 2: Actual torque converter slip rate [ETR] is more than 99 %, or less than 130 % for at least 1 second.

CVT lock-up clutch control solenoid valve stuck on

Confirmation Procedure
Operating Condition

1.
Start the engine.
2.
With the brake pedal pressed, place the shift lever in from N position/mode to D position/mode.
3.
Drive the vehicle at 12 mph (20 km/h) or less for at least 10 seconds.
4.
Slow down and stop the vehicle.
5.
Turn the vehicle to the OFF (LOCK) mode.
6.
Repeat Driving Pattern steps 1 through 4.
Drive the vehicle in this manner only if the traffic regulations and ambient conditions allow.
With the HDS
None.

Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected during the first drive cycle, a Pending DTC is stored in the TCM memory. If the malfunction returns in the next (second) drive cycle, the MIL comes on, the shift position indicator blinks, and a Confirmed DTC and the freeze data are stored.

Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The MIL is cleared if the malfunction does not return in three consecutive trips in which the diagnostic runs. The MIL, the Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool Clear command.
