P0746 - Pressure Control Solenoid "A" Performance (Shift Solenoid Valve SL1) (Continued)
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 P0746, P0873 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 P0746, P0873 and P2714 are output, perform troubleshooting for those DTCs first.
B -- GO TO DTC P0873 FLOWCHART P0873
C -- GO TO DTC CHART Automatic Transmission System - AA80E
A -- Continue to next step.
2. 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 at a low speed and perform the inspection.
Result:
B -- INSPECT SHIFT SOLENOID VALVE SLT
A -- Continue to next step.
3. INSPECT SHIFT SOLENOID VALVE SL1
(a) Remove the shift solenoid valve SL1 Disassembly.
(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.
Result:
B -- INSPECT TRANSMISSION VALVE BODY ASSEMBLY
A -- REPLACE SHIFT SOLENOID VALVE SL1 Disassembly
4. INSPECT SHIFT SOLENOID VALVE SLT
(a) Remove the shift solenoid valve SLT Disassembly.
(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.
NG -- REPLACE SHIFT SOLENOID VALVE SLT Disassembly
OK -- Continue to next step.
5. INSPECT TRANSMISSION VALVE BODY ASSEMBLY
(a) Check the transmission valve body assembly Disassembly.
OK:
There are no foreign objects on any valve.
NG -- REPAIR OR REPLACE TRANSMISSION VALVE BODY ASSEMBLY Removal
OK -- REPAIR OR REPLACE AUTOMATIC TRANSMISSION ASSEMBLY Removal
