U760E AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P2759: Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)
P2759 - Torque Converter Clutch Pressure Control Solenoid Control Circuit Electrical (Shift Solenoid Valve SLU)

DESCRIPTION

Refer to the system description for DTC P2757 P2757.





MONITOR DESCRIPTION

When an open or short in a shift solenoid valve (SLU) circuit is detected, the ECM determines there is a malfunction. The ECM will turn on the MIL and store this DTC.

INSPECTION PROCEDURE

NOTICE:
Perform the universal trip to clear permanent DTCs Reading and Clearing Diagnostic Trouble Codes.

PROCEDURE

1. CHECK HARNESS AND CONNECTOR (SHIFT SOLENOID VALVE SLU CIRCUIT)

(a) Disconnect the ECM connector.





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

Standard Resistance:





Text in Illustration





NG -- CHECK HARNESS AND CONNECTOR (ECM - WIRING HARNESS CONNECTOR)

OK -- REPLACE ECM Components

2. CHECK HARNESS AND CONNECTOR (ECM - WIRING HARNESS CONNECTOR)

(a) Disconnect the harness connector from the wiring harness connector.

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

Standard Resistance:





NG -- REPAIR OR REPLACE HARNESS OR CONNECTOR
OK -- Continue to next step.

3. INSPECT TRANSMISSION WIRE (SLU)

(a) Remove the wiring harness connector from the automatic transaxle.





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

Standard Resistance:

NG -- INSPECT SHIFT SOLENOID VALVE SLU

OK -- REPLACE WIRING HARNESS CONNECTOR Components

4. INSPECT SHIFT SOLENOID VALVE SLU

(a) Remove shift solenoid valve SLU.





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

Standard Resistance:





(c) Connect a battery positive (+) lead with a 21 W bulb to terminal 2 and a negative (-) lead to terminal 1 of the solenoid valve connector. Then check that the valve moves and makes an operating sound.

OK:

Valve moves and makes an operating sound.
