DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

WARNING:

If you do not select a suitable route and take proper precautions when performing a road test, an accident can occur.

- Select a level road with no traffic to minimize the risk of accident.
- Perform the test extremely carefully.
- Perform the road test using 2 persons, a driver and an assistant.

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 in "P" range for 20 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 TCC pressure control solenoid valve circuit for ground short

Disconnect TCM connectors.
Check for proper connection to TCM at terminals "E92-3" and "E92-5".
If connection is OK, check continuity between terminal "E92-5" of disconnected harness side TCM connector and ground.

Is continuity indicated?
YES -
TCC pressure control solenoid valve circuit is shorted to ground. If circuit is OK, go to Step 4.
NO -
Go to Step 3.

3. Check TCC pressure control solenoid valve circuit for open

Check resistance between terminal "E92-3" and "E92-5" of disconnected harness side TCM connector.

Is it infinity?
YES -
TCC pressure control solenoid valve circuit is open. If circuit is OK, go to Step 4.
NO -
Go to Step 4.

4. Check TCC pressure control solenoid valve

Check TCC 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 TCC 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.
