DTC Detecting Condition and Trouble Area
DTC Confirmation Procedure
1) Connect scan tool to DLC with ignition switch OFF, if available.
2) Clear DTC in TCM memory.
3) Start engine.
4) Keep engine running at idle speed for 10 seconds or more.
5) Check DTC.
DTC Troubleshooting
1. TCM 3. A/T
2. Pressure control solenoid valve [A]: Terminal arrangement of TCM connector (Viewed from harness side)
DTC DETECTING CONDITION TROUBLE AREA

comparing with TCM command value.
• Pressure control solenoid valve circuit shorted
to power circuit.
• Pressure control solenoid valve malfunction
• TCM

1Was “Automatic Transaxle Diagnostic Flow Table”
performed?
Go to Step 2. Go to “Automatic Tran-
saxle Diagnostic Flow
Tabl e ” in this section.
2 Check pressure control solenoid circuit for IG short
1) Connect valve body harness connector.
2) Disconnect TCM connectors.
3) Check for proper connection to TCM at termi-
nal “E13-2” and “E13-4”.
4) If connection is OK, turn ignition switch ON and
measure voltage between terminal “E13-4” of
disconnected harness side TCM connector
and ground.
Is it 0 – 2 V?
Go to Step 3. “BRN/YEL” or “LT GRN/
RED” circuit shorted to
power circuit.
