Wiring Diagram
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 30 seconds or more.
5) Stop vehicle and check DTC.3Check for pressure control solenoid valve circuit
1) Disconnect TCM connectors.
2) Check for proper connection to TCM at terminals “C06-
2” and “C06-4”. If connection is OK, check circuit for
open, short, and high resistance for the following circuit.
• 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.
Are they in good condition?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.Repair “LT GRN/BLK”
and/or “GRY” circuit. Step Action Yes No
