INSPECTION PROCEDURE

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

PROCEDURE

1. CHECK DTC OUTPUT (IN ADDITION TO DTC P0771, P0776 AND P2714)

(a) Connect the Techstream to the DLC3.

(b) Turn the engine switch on (IG).

(c) Turn the Techstream on.

(d) Enter the following menus: Powertrain / ECT / Trouble Codes.

(e) Read the DTCs using the Techstream.

Result:





HINT
If any other codes besides P0771, P0776 and P2714 are output, perform troubleshooting for those DTCs first.

B -- INSPECT SHIFT SOLENOID VALVE SL2

C -- GO TO DTC CHART Automatic Transmission System - AA80E
A -- Continue to next step.

2. CLEAR DTC AND PERFORM STALL SPEED TEST

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
Write down the currently output DTCs before clearing them.

(b) Perform the stall speed test Mechanical System Tests.

Result:





B -- INSPECT SHIFT SOLENOID VALVE SLT
A -- Continue to next step.

3. CLEAR DTC AND PERFORM RUNNING TEST

(a) Clear the DTCs Reading and Clearing Diagnostic Trouble Codes.

HINT
Write down the currently output DTCs before clearing them.

(b) Start the engine, drive the vehicle and perform the inspection.

Result:





HINT
*: If the gear is shifted to 5th gear or above, gear shifts will no longer be able to be performed. When performing the test again, first clear the DTCs.

B -- INSPECT SHIFT SOLENOID VALVE SL2

C -- INSPECT SPEED SENSOR TERMINAL (NC3 TERMINAL)
A -- Continue to next step.

4. INSPECT SHIFT SOLENOID VALVE SR

(a) Remove the shift solenoid valve SR Disassembly.





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

Standard Resistance:





(c) Connect a battery positive (+) lead to the terminal of the solenoid valve connector, and a negative (-) lead to the solenoid body. Then check that the valve moves and makes an operating sound.

OK:

Valve moves and makes an operating sound.

Result:
