DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF.
2) Clear DTCs in TCM and ECM memories by using scan tool.
3) Start engine.
4) Keep engine running at idle speed for 10 seconds or more.
5) Check DTC, pending DTC and freeze-frame data.
DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check pressure control solenoid valve circuit for power
supply short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminal "E92-2"
and "E92-4".
3) If connection is OK, turn ignition switch ON and measure
voltage between terminal "E92-2" of disconnected
harness side TCM connector and ground.
Is it 0 – 2 V?
3 Inspection pressure control solenoid valve
1) Inspection pressure control solenoid valve referring to
"Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B,
TCC Pressure Control Solenoid and Pressure Control
Solenoid Inspection: ".
Is check results satisfactory?
