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 solenoid valve circuit for power supply short Disconnect TCM connectors. Check for proper connection to TCM at terminals "E92-16" (for solenoid valve-A), "E92-15" (for solenoid valve-B) or "E92- 14" (for solenoid valve-E). If connection is OK, turn ignition switch ON and measure voltage between terminal "E92- 16" (for solenoid valve-A), "E92-15" (for solenoid valve-B) or "E92-14" (for solenoid valve-E) of disconnected harness side TCM connector and ground. Is it 0 - 2 V?	Solenoid valve-A, -B or -E control circuit is shorted to power supply circuit.	Go to Step 3.
3	Check solenoid valve circuit for open Check continuity between terminal "E92- 16" (for solenoid valve-A), "E92-15" (for solenoid valve-B) or "E92-14" (for solenoid valve-E) of disconnected harness side TCM connector and ground. Is it infinity?	Solenoid valve-A, -B or -E control circuit is open circuit. If circuit is OK, go to step 4.	Go to Step 4.
4	Inspection solenoid valve Inspection 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 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 .
