DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Clear DTC.
2) Start engine and run it for 1 minute.
3) Check DTC.
DTC Troubleshooting
DTC detecting condition Trouble area
Value of pressure control solenoid valve output
current is too low for 12.5 seconds or more.
(1 driving cycle detection logic) • Pressure control solenoid valve or its circuit malfunction.
• TCM
Step Action Yes No
1 Was “A/T System Check” performed? Go to Step 2. Go to “A/T System
Check”.
2 Check pressure control solenoid valve resistance
1) Turn ignition switch to OFF position.
2) Disconnect valve body harness connector (1) on
transaxle.
3) Check for proper connection to “LT GRN” and “GRY”
terminals of valve body harness connector.
4) Check resistance of pressure control solenoid valve.

Between (3) terminal of valve body harness
connector and vehicle body ground (2): Infinity
Is check results satisfactory?
Go to Step 4. Replace pressure
control solenoid valve or
lead wire.
3 Check pressure control solenoid valve circuit for
ground short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at terminals “C06-
2” and “C06-4”.
4) If connections are OK, check continuity between
terminal “C06-4” of disconnected harness side TCM
connector and ground.
Is continuity indicated?
“LT GRN/BLK” or “GRY”
circuit shorted to
ground. Go to Step 5.
