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
4 Check pressure control solenoid valve circuit for open
1) Check resistance between terminals “C06-2” and “C06-
4” of disconnected harness side TCM connector.
Is it infinity?
“LT GRN/BLK” or “GRY”
circuit open. Intermittent trouble or
faulty TCM. Check for
intermittent referring to
“Intermittent and Poor
Connection Inspection
in Section 00”. If OK,
substitute a known-
good TCM and recheck.
Step Action Yes No
1. TCM 3. Terminal arrangement of TCM connector (viewed from harness side)
2. Pressure control solenoid valve
DTC detecting condition Trouble area
Value of pressure control solenoid valve output current is
too high for 12.5 seconds or more.
(1 driving cycle detection logic) • Pressure control solenoid valve or its circuit malfunction.

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 circuit for IG
short
1) Turn ignition switch to OFF position and disconnect TCM
connectors.
2) Check for proper connection to “C06-2” and “C06-4”.
3) If OK, turn ignition switch to ON position and measure
voltage between “C06-4” terminal of disconnected
harness side TCM connector and ground.
Is it 0 V?
Go to Step 3. “LT GRN/BLK” or “GRY”
circuit shorted to power
circuit.
