DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check TCC solenoid valve resistance
1) Turn ignition switch to OFF position.
2) Disconnect valve body harness connector (1), (2) on
automatic transaxle.
3) Check for proper connection to terminal at "WHT/BLU"
and "WHT/BLK" circuit.
4) Check resistance of TCC solenoid valve.
TCC solenoid valve resistance
Between terminals of transaxle side valve body
harness connector: 5.0 – 5.6 Ω at 20 °C (68 °F)
Between terminals of transaxle side valve body
harness connector and transaxle: Infinity
Is check results satisfactory?
3 Check for pressure control solenoid valve circuit
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals "C34-
3" and "C34-5". If connection is OK, check circuit for
open, short and high resistance for the following circuit.
• Between "C34-3" terminal of TCM connector and
"WHT/BLK" terminal of valve body harness connector.
