DTC Detecting Condition and Trouble Area






DTC Confirmation Procedure

WARNING:

- When performing a road test, select a place where there is no traffic or possibility of a traffic accident and be very careful during testing to avoid occurrence of an accident.
- Road test should be carried out with 2 persons, a driver and a tester, on a level road.

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 and warm it up to normal operating temperature.
4) Turn O/D off switch OFF. (Confirm "O/D OFF" lamp does not light.)
5) Drive vehicle with 3rd or 4th gear in "D" range and lock-up ON for 10 seconds or longer referring to Automatic Gear Shift Diagram (for 2WD Model) or Automatic Gear Shift Diagram (for 4WD Model). (Reference: less than 20% throttle opening and at vehicle speed of 80 km/h (50 mile/h) or more)
6) Decrease vehicle speed gradually and stop vehicle.
7) 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.

2. Check TCC solenoid valve resistance.

Turn ignition switch OFF.
Disconnect valve body harness connector (1) on transaxle (3).
Check for proper connection to solenoid at "BLU/WHT" circuit.
Check resistance of solenoid.

Resistance between terminal (2) of transaxle side valve body harness connector and transaxle
11 - 15 ohms (at 20 °C (68 °F))





Is check result satisfactory?
YES
Go to Step 3.
NO
Replace TCC solenoid valve or lead wire.

3. Check TCC solenoid circuit for ground short.

Disconnect TCM connectors.
Check for proper connection to TCM at terminal "G08-12" of TCM connector.
If connection is OK, check continuity between terminal "G08-12" of disconnected harness side TCM connector and ground.

Is continuity indicated?
YES
"BLU/WHT" circuit shorted to ground.
NO
Intermittent trouble or faulty TCM. Check for intermittent referring to Intermittent and Poor Connection Inspection. If OK, substitute a known-good TCM and recheck.
