DTC Troubleshooting
Step
1 Was "A/T System Check" performed?
2 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 shift terminals of transaxle side valve body
harness connector: 5.0 – 5.6 Ω at 20 °C (68 °F)
Between shift terminals of transaxle side valve body
harness connector and transaxle: Infinity
Is check results satisfactory?
3 Check TCC solenoid valve circuit for ground short
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals "C06-
3" and "C06-5".
3) If connection is OK, check continuity between terminal
"C06-5" of disconnected harness side TCM connector
and ground, between terminal "C06-3" of disconnected
harness side TCM connector and ground.
Are continuity indicated?

Intermittent trouble or
faulty TCM.
Check for intermittent
referring to "Intermittent
and Poor Connection
Inspection in Section

If OK, substitute a
known-good TCM and
recheck.
