Diagnostic Procedure

1. CHECK PRESSURE CONTROL SOLENOID VALVE A SIGNAL 

   With CONSULT-II 

   1. After warming up the engine and transaxle, turn ignition switch "OFF".
   2. Turn ignition switch "ON". (Do not start engine.)
   3. Select "DATA MONITOR" mode for "TRANSMISSION" with CONSULT-II.
   4. Read out the value of "PC SOL A OUT" and "PC SOL A MON".

   4. Reinstall any part removed.

   OK or NG 

   1. OK: GO TO 4.
   2. NG: Replace the transaxle assembly. Refer to "REMOVAL AND INSTALLATION ".
4. CHECK HARNESS BETWEEN TCM AND PRESSURE CONTROL SOLENOID VALVE A 

   Check the following.

   • Open or short-circuit in the harness between TCM and pressure control solenoid valve A.

   OK or NG 

   1. OK: GO TO 5.
   2. NG: Repair or replace damaged parts.
5. CHECK DTC 

   Perform "DTC Confirmation Procedure". Refer to "DTC CONFIRMATION PROCEDURE ".

   OK or NG 

   1. OK: INSPECTION END 
   2. NG: GO TO 6.
6. CHECK TCM 

1. Check TCM input/output signal.
2. If NG, recheck TCM pin terminals for damage or loose connection with harness connector.

OK or NG 

1. OK: INSPECTION END 
2. NG: Repair or replace damaged parts.
