P2716

DESCRIPTION

Refer to DTC P2714 (Click here).

DTC No.	DTC Detection Condition	Trouble Area
P2716	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

Reference (Using an oscilloscope):
Check the waveform between the terminals SLT+ and SLT- of the ECM connector

Standard:

Refer to the illustration.

Terminal	SLT+ - SLT-
Tool setting	5 V/DIV., 1 ms./DIV.
Vehicle condition	Engine idle speed

MONITOR DESCRIPTION

When an open or short in the linear solenoid valve (SLT) circuit is detected, the ECM interprets this as a fault. The ECM will turn on the MIL and store the DTC.

INSPECTION PROCEDURE

1. INSPECT TRANSMISSION WIRE (SLT)

1. Disconnect the transmission wire connector from the transmission.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Specified Condition 20°C (68°F)
   13 (SLT+) - 5 (SLT-)	5.0 to 5.6 Ω

3. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for short):

   Tester Connection	Specified Condition
   13 (SLT+) - Body ground	10 kΩ or higher
   5 (SLT-) - Body ground	↑

NG	Go to step 3

OK

2. CHECK HARNESS AND CONNECTOR (TRANSMISSION WIRE - ECM)

1. Connect the transmission wire connector to the transmission.

2. Disconnect the ECM connector.

3. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Specified Condition 20°C (68°F)
   E4-35 (SLT+) - E4-34 (SLT-)	5.0 to 5.6 Ω

4. Measure the resistance according to the value(s) in the table below.

   Standard resistance (Check for short):

   Tester Connection	Specified Condition
   E4-35 (SLT+) - Body ground	10 kΩ or higher
   E4-34 (SLT-) - Body ground	↑

NG	REPAIR OR REPLACE HARNESS OR CONNECTOR

OK
REPLACE ECM

3. INSPECT SHIFT SOLENOID VALVE SLT

1. Remove the shift solenoid valve SLT.

2. Measure the resistance according to the value(s) in the table below.

   Standard resistance:

   Tester Connection	Specified Condition 20°C (68°F)
   1 - 2	5.0 to 5.6 Ω

3. Connect the positive (+) lead with a 21 W bulb to terminal 2 and the negative (-) lead to terminal 1 of the solenoid valve connector, then check the movement of the valve.

   OK:

   The solenoid makes an operating sound.
   

NG	REPLACE SHIFT SOLENOID VALVE SLT

OK
REPAIR OR REPLACE TRANSMISSION WIRE
