Wiring Diagram










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 and start engine.
3) Keep engine running at idle speed for 10 minutes or more.

DTC Troubleshooting

1.
Was "A/T System Check" performed?
YES
Go to Step 2.
NO
Go to A/T System Check.

2. Check transmission fluid temperature sensor circuit for ground short

Turn ignition switch OFF.
Disconnect TCM connectors from TCM.
Check for proper connection to transmission fluid temperature sensor at terminals "G08-5" and "G08-14".
If OK, check continuity between terminals "G08-5" of disconnected harness side TCM connector and ground.

Is continuity indicated?
YES
"BLU/ORN" circuit shorted to ground.
NO
Go to Step 3.

3. Inspect transmission fluid temperature sensor

Inspect transmission temperature sensor referring to Transmission Fluid Temperature Sensor Inspection.

Is result satisfactory?
YES
Intermittent trouble or faulty TCM.
Check for intermittent referring to Intermittent and Poor Connection Inspection.
If OK, substitute a known-good TCM and recheck.
NO
Replace transmission fluid temperature sensor.
