Toyota 2013 Auris won't lock front doors or fold door mirror

Hi, 

I have a Toyota Auris Excel 2013

This fault was intermittent but now it is permanent. 

Either using the door handles' sensor or the key fob, it won't look the front doors or fold thedoor mirrors. It attempts to start the process bit does not complete it. 

It does the same on both key fobs. They both have new batteries. 

However, it does lock the rear doors & the boot. 

Any idea what it could be? 

Thank you

Each door latch has a latch position sense detector switch. If during a lock operation, it detects "not latched" it auto unlocks the doors. Eg normal behaviour if you try to remote lock with a door ajar.

So either you have a stuck latch detector switch, or broken wire(s) in the door conduit jamb loom. Toyota techstream should be able to assist.

 Broken loom wires would explain intermittent behaviour.

Thank you so much. I am taking it to the main dealership tomorrow. 

The lady at the service desk told me to take for a long drive to charge the hybrid Battery! I replied how long as I had done a 150 miles trip & the fault is still there. 

I don't know why would they employ someone at a service desk who clearly haven't got a. Clue. 

Thank you.

Ok good luck, hopefully you have some kind of warranty.

They should be able to pinpoint the problem using techstream, rather than fire the parts cannon at it.

Dont let them fob you off with the latter, if you are paying for a fix.

Most likely its a faulty door lock unit, or door loom. Less likely is body ECU.

I had a similar problem in another car I had.

When I closed the doors with the key fob, one door randomly kept open. But it was only "one" door. The reason was a faulty latch detector switch.

Here it's strange that both front doors and mirrors are faulty. Perhaps it's a wire which somehow interconnects them.

Please keep us updated!

I can get the door mirrors fold by using the overide button on the dash. 

It is strange as it was first intermittent & now the fault is permanent. 

Cable loom could be a possibility? 

 

If it gets fixed, then I will post it here.

I am sure they can fix it, but may be costly if its not covered under a warranty of some sort

For a car of this age, i would consider a local auto electrician to diagnose and repair. It cant be more than 1-2 hours labour, and a used door latch (about £20),  or solder repair to broken door loom wires would be more cost effective.

Les see what Toyota say.
