Diagnostic Procedure

WARNING: This page is about a different car, the 2005 Nissan Quest. However, it is still accessible from the selected car via links, so may be relevant.
  1. CHECK SHIFT SOLENOID VALVE C SIGNAL 

    With CONSULT-II 

    1. Start engine.
    2. Select "A/T" with "DATA MONITOR" mode in CONSULT-II.
    3. Drive vehicle and read out the value of "SFT SOL C OUT" and "SFT SOL C MON".
