DTC Detecting Condition and Trouble Area






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

1.
Was "A/T System Check" performed?
YES -
Go to Step 2.
NO -
Go to A/T System Check 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 terminal "E92-2" and "E92-4".
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?
YES -
Go to Step 3.
NO -
Pressure control solenoid valve circuit is shorted to power circuit.

3. Check pressure control solenoid valve

Check pressure control solenoid valve referring to Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Inspection Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Inspection.

Is check results satisfactory?
YES -
Intermittent trouble or faulty TCM. Check for intermittent trouble referring to Intermittent and Poor Connection Inspection Intermittent and Poor Connection Inspection. If OK, substitute a known-good TCM and recheck.
NO -
Replace defective pressure control solenoid valve referring to Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Removal and I Solenoid Valves (Shift Solenoid-A, Shift Solenoid-B, TCC Pressure Control Solenoid and Pressure Control Solenoid) Removal and Installation.
