Introduction
Some 2006 model year GS 300 vehicles may exhibit a MIL "ON" condition with DTC P0751 stored (Shift Solenoid "A" Performance). DTCs P2714 or
P0894 may also be stored. The Engine Control Module/ECM (SAE term: Powertrain Control Module/PCM) detection logic for DTC P0751 has been
revised to prevent false detection of P0751 and erroneous MIL "ON".
To properly address this condition two different repair procedures are provided. Carefully review the Repair Procedure Overview below and all steps of
this bulletin BEFORE beginning any repair.
