DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 Check TCC solenoid valve circuit for IG short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminal "C06-3"
and "C06-5".
4) If connection is OK, turn ignition switch ON and measure
voltage between terminal "C06-3" of disconnected
harness side TCM connector and ground between
terminal "C06-5" of disconnected harness side TCM
connector and ground.
Are voltage 1 V or less?
3 Check TCC solenoid valve resistance
1) Turn ignition switch OFF.
2) Disconnect valve body harness connector (1), (2) on
automatic transaxle.
3) Check for proper connection to solenoid at "WHT/BLU"
and "WHT/BLK" circuits.
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?
