1. TCM 3. Terminal arrangement of TCM connector (viewed from harness side)
2. Pressure control solenoid valve
DTC detecting condition Trouble area
Difference between actual current of pressure control
solenoid valve and current of pressure control
solenoid valve calculated by TCM is more than
specification.
(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 DTC check
Is DTC P0962 or DTC P0963 detected?
Go to applicable DTC
diag. flow. Go to Step 3.
3 Check pressure control solenoid valve
1) Turn ignition switch to OFF position.
2) Disconnect connectors from TCM and transaxle (valve
body harness connector).
3) Check pressure control solenoid valve for resistance
referring to “Pressure Control Solenoid Valve
Inspection”.
Is it in good condition?
Go to Step 4. Replace pressure
control solenoid valve.
4 Check pressure control solenoid valve circuit
1) Check the following circuit for high resistance.
• Between “C06-2” terminal of TCM connector and “LT
GRN/BLK” terminal of valve body harness connector.
• Between “C06-4” terminal of TCM connector and
“GRY” terminal of valve body harness connector.
Is each resistance 1
Ω
or less?
Substitute a known-
good TCM and recheck. Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection in Section
00”.
