sorry ....its a Renault trafic 3 2015

 

Anyone?

 

When you try to lock are ALL of the actuators moving, (the one in the rear door?) but they bounce back and it doesn't lock?
The sensing afaik looks for a momentary pulse to ground on one of the wires, I don't know which wire, but you might be able to see it if you operate the locking with a voltmeter attached.
Does opening the door put your interior light on?

 

Tks for reply, yes all doors lock and immediately unlock. Tbh if i repeatedly press fob 5 to 10 times i might get it to stay locked.
If it looks for a ground is there a micro switch within the locks to make this ground connection. The front doors latches seem to detect when door is open and im guessing the rear door latch position is not completing the circuit (layman's terms).
I'll try wit multimeter and maybe short to ground to test

 

Lubricate anything that moves in the door, if it works sometimes it sounds like something is a bit sticky, so perhaps not making it far enough to cause contact. Don't go shorting random wires to ground, it will end badly.

 

Tks , you got me thinking & gave up poking around back door .. sliding door was cause. The circuit (2 bottom pins on the sliding door connectors) is showing high resistance 90 ohms when the latch is locked.
I'll access lock next few days and see can i get better connection. Meantime I'll short these connectors to bypass the lock wiring

 

You didn't say it had a sliding door, it's a common fault that the connections go faulty, there are lots of posts about this.
Clean the connectors and make sure the pins slide freely, also check wiring behind connectors for corrosion. You may need to tweak things to align the connections
(That doesn't tally with the tried 5 or 10 times and it worked unless you moved the sliding door)

 

Hi Wozz, I am having a similar problem in that my barn doors are not locking as there is no voltage going to the lock. I have removed the lock and checked continuity between the cabling between the connector at rear pillar and connections to lock all good. Where does the voltage come from. I don’t have a schematic. I have lightly sanded sliding door contacts and applied electrical contact spray to no avail, I suppose I should remove contact on sliding door and check connections, what is your thoughts, regards, Noel

 

I'm no expert...and apologies I don't have a wiring diagram.
Is the sliding door locking? If the sliding door is working (locking) those contacts are OK
Can you hear any noise slight click (anything) from the rear doors lock at all when the C. locking is operated?

The locks do fail, <- have you worked it back and forth manually? (The lack of voltage might be a red herring depending on where/how you measured).
