DESCRIPTION
Refer to the description for DTC P27137F
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
|---|---|---|---|---|---|---|
| P271313 | Pressure Control Solenoid "D" Circuit Open | Open or short is detected in shift solenoid valve SLT circuit for 1 second or more while driving (1 trip detection logic). | ·
Open or short in shift solenoid valve SLT circuit ·
Shift solenoid valve SLT ·
ECM |
Comes on | DTC stored | SAE Code:
P2716 |
MONITOR DESCRIPTION
When an open or short in the shift solenoid valve SLT circuit is detected, the ECM interprets this as a fault. The ECM will illuminate the MIL and store the 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.
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 at least 30 seconds.
Turn the ignition switch to ON and turn the GTS on.
Start the engine.
Enter the following menus: Powertrain / Transmission / Utility / All Readiness.
Input the DTC: P271313.
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.

PROCEDURE
| *a | Component without harness connected
(Transmission Wire) |
Disconnect the transmission wire connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 13 (SLT+) - 14 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω 13 (SLT+) - Body ground Always 10 kΩ or higher 14 (SLT-) - Body ground Always 10 kΩ or higher
- Result:
Proceed to OK NG
OK
NG
| *a | Rear view of wire harness connector
(to ECM) |
Disconnect the ECM connector.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition E3-13 (SLT+) - E3-12 (SLT-) 20°C (68°F) 5.0 to 5.6 Ω E3-13 (SLT+) - Body ground Always 10 kΩ or higher E3-12 (SLT-) - Body ground Always 10 kΩ or higher
- Result:
Proceed to OK NG
OK
NG
| *1 | Shift Solenoid Valve SLT |
Remove shift solenoid valve SLT.
Measure the resistance according to the value(s) in the table below.
- Standard Resistance:
Tester Connection Condition Specified Condition 1 - 2 20°C (68°F) 5.0 to 5.6 Ω
Apply 12 V battery voltage to the shift solenoid valve and check that the valve moves and makes an operating noise.
- OK:
Measurement Condition Specified Condition ·Battery positive (+) with a 21 W bulb → Terminal 1
·Battery negative (-) → Terminal 2
Valve moves and makes an operating noise
- Result:
Proceed to OK NG
OK
NG
