DTC Troubleshooting

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 shift solenoid valve circuit for power supply short Disconnect TCM connectors. Check for proper connection to TCM at terminal "E92-16" (for shift solenoid valve-A), "E92-15" (for shift solenoid valve-B). If connection is OK, turn ignition switch ON and measure voltage between terminal "E92-16" (for shift solenoid valve-A), "E92-15" (for shift solenoid valve-B) of disconnected harness side TCM connector and ground. Is it 0 - 2 V?	Go to Step 3.	DTC P0974: Shift solenoid valve-A circuit is shorted to power supply circuit. DTC P0977: Shift solenoid valve-B circuit is shorted to power supply circuit.
3	Check solenoid valve circuit for open Check continuity between terminal "E92- 16" (for shift solenoid valve-A) or "E92- 15" (for shift solenoid valve-B) of disconnected harness side TCM connector and ground. Is it infinity?	DTC P0974: Shift solenoid valve-A circuit is open circuit. DTC P0977: Shift solenoid valve-B circuit is open circuit. If circuit is OK, go to Step 4.	Go to Step 4.
4	Check solenoid valve Check 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?	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, TCC PRESSURE CONTROL SOLENOID AND PRESSURE CONTROL SOLENOID) REMOVAL AND INSTALLATION .
