Warning lights electrical problems

Recommended Posts

Hi I need help. I have a rx400h 2006 150,000 miles, it's been faultless until the other day I came to start car and it started fine and then hybrid check light and Vsc light came on, I continued to drive and got home fine, the next day I decided to replace 12v Battery, but it is still the same, I also have various other electrical problems that are related to this.....tailgate won't open, mirrors won't work, electric Windows only work off individual button, no cruise, afs lights don't work, central locking works off fob( delayed) but not off button inside car, also you can hear the central locking make a noise once the door is closed. The car still drives fine, charges as it should. I've checked all fuses, I've plugged it into diagnostic and it only shows 1 code, u0146....lost communication with gateway a. My sister has identical car so I changed the gateway ecu over but made no difference, I'm wondering if anyone may have any ideas on this before I bite the bullet and take it to the dealers? Thanks in advance

Hi Greg and welcome to the LOC, we are a friendly bunch and some of us even know how to pull them to bits and put them back together again, with of course the one bolt and washer left over.

I cant help with your present queries but I'm sure someone will be along ASAP.

We recommend you spend a couple of mins looking over the rules of the LOC, we will be asking questions later

Hi. Cars this complex need to be taken to the dealers I think. Long gone are the days when you can do them on the drive

I think the Gateway ECU may be faulty but I don't think you can just swap it out with a known good one to confirm that without it being coded to the car first.

    1. 1. If you were to consider buying a Hybrid model over 5 years old, would you be worried about the reliability of the Hybrid system?


      • Not really as Hybrid systems are always reliable
      • Not if it had a Manufacturers Warranty on the Hybrid system
      • I would not buy a Hybrid model over 5 years old
