DTC TROUBLESHOOTING CHART

Step Action YES NO
Was "A/T System Check" performed?  Go to Step 2. Go to A/T SYSTEM CHECK .
Check pressure control solenoid valve circuit for power supply short 
  1. Disconnect TCM connectors.
  2. 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).
  3. 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.
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 .
