DTC TROUBLESHOOTING CHART

Step	Action	YES	NO
1	Was "A/T System Check" performed?	Go to Step 2.	Go to A/T SYSTEM CHECK .
2	Check pressure control solenoid valve circuit for power supply short Disconnect TCM connectors. Check for proper connection to TCM at terminals "E92-2" and "E92-4" (for pressure control solenoid valve-A), "E92-9" and "E92- 22" (for pressure control solenoid valve-B) or "E92-19" and "E92-21" (for pressure control solenoid valve-C). If connection is OK, turn ignition switch ON and measure voltage between terminal "E92-2" (for pressure control solenoid valve-A), "E92-9" (for pressure control solenoid valve-B) or "E92- 19" (for pressure control solenoid valve-C) of disconnected harness side TCM connector and ground. Is it 0 - 2 V?	Go to Step 3.	Pressure control solenoid valve-A, -B or -C control or ground circuit is shorted to power supply circuit.
3	Inspection pressure control solenoid valve Inspection pressure control solenoid valve referring to SOLENOID VALVES (SHIFT SOLENOID-A, SHIFT SOLENOID-B, SHIFT SOLENOID-E, TCC SOLENOID, PRESSURE CONTROL SOLENOID-A, PRESSURE CONTROL SOLENOID-B, AND PRESSURE CONTROL SOLENOID-C) INSPECTION Is check results satisfactory?	Intermittent trouble or faulty TCM. Check for intermittent trouble referring to INTERMITTENT AND POOR CONNECTION INSPECTION . If OK, substitute a known-good TCM and recheck.	Replace defective pressure control solenoid valve referring to SOLENOID VALVES (SHIFT SOLENOID-A, SHIFT SOLENOID-B, SHIFT SOLENOID-E, TCC SOLENOID, PRESSURE CONTROL SOLENOID-A, PRESSURE CONTROL SOLENOID-B, AND PRESSURE CONTROL SOLENOID-C) REMOVAL AND INSTALLATION .
