Location ecm on 2010 Lexus rx350 awd

Hello, replacing the ECM is not likely to fix anything. A diagnostic test is needed to find out what fault you have and why it's happening. Rarely is the ECM at fault. Sure, it's possible, but it's not common. Also, are you using a diagnostic tool to replace the programmable module as per needed? I'm seeing the ECM located near the driver's side fender area of the engine compartment. Use this link to find some shops near you that can help with your concern: www.repairpal.com/repair-shops
