2014 bonnet locking issue

[Turtle60]

My 2014 Bonnet has become a proper pain to lock. Every time the drivers side just won’t lock down which apart from being loose means you can’t lock the car. Passenger side never an issue. If I slam the bonnet it will eventually lock. I can’t even push it to lock. The bonnet needs a good slam.
ive sprayed latches etc but no good. Do these have an adjustment somewhere. Feels something just not letting it close quite enough for the bonnet to do its final lock.
any ideas
Cheers
Steve

Can't help, but the following instructions are from the workshop manual, but they relate to removing/replacing the Hood Latch Panel:
15. Adjust both of the hood latches.Loosen the 4 hood latch Torx bolts.Lower the hood and check for alignment.Open the hood and tighten the Torx bolts to 10 Nm(7 lb.ft).Check for the correct operation of the hood safety catch.If necessary, repeat the above adjustment procedure.
16. Connect the battery ground cable.

Look at the front corners under the bonnet. Each corner has a round black rubber bump stop.

You will find these are also helical height adjustable.

Screw them a single turn down and ensure both are same height.

Then keep adjusting till closed but still firm when shut, they are also designed to stop bonnet vibration offroad.

I have the same issue with the red alert light coming on even tho I've slamned the bonnet and it is def closed😞

I can't see where the switch is located just in case it's faulty. I've lubed the catches and dropped the spiral stops a bit. But that puts the bonnet out of alignment....anyhow...no red dash light so far....1 day🙄

Anyone know where the switch is locate?

Part of the drivers side latch. Just to side of radiator you’ll see the plug and module. Bridge the wires and problem goes away.

Normal failure mode is random intruder security alarm going off all the time. I tried every way of cleaning it to no avail. You can easily buy and replace the switch module that clips onto the latch but you don’t miss it once disconnected and bridged. I use bright red electrical tape on the bridged connector that reminds me and anyone that looks in of the mod.

And on road when road trains (full 53m) go past in the opposite direction. :o

Argh..did again..so screwed the stops down again..and slammmmmmed it shut..again..

8 months and no alarms/faults...had to happen some time I guess😞

The failure process is unstoppable and irreversible

Thanks. Looked at this and both in as far as possible. So then took them out and tried it but no luck. The latch looks a bit dirty so I will remove a give it a clean and lube and report back.

Interesting they are fully in as mine were not even half way. Yeah we live on a dirt road and the engine bay gets quite dirty...much more than the TD5 did ....so I'm too pulling the latches to clean them up...soon.

[INter674]

Okay...3 adjustments later and the warning light still comes on so time to pull the latches and switch to clean and check operation. Bonnet is def closed so gotta be the cable/latch/switch mechanisms.

See how it goes😞

Had a good look at the switch. It appears to be an exposed strip of metal which is horizontal under the keeper. The keeper pivots down onto it when the striker is latched. In the pic it is the shiny forked metal strip.

Being horizontal any dust dirt and lube will collect on it and eventually prevent the keeper from shorting out the switch/light curcuit.

I could be wrong but that arrangement seems like its waiting to fail.

A good clean with degreaser should rectify...we'll see.

Edit...on closer exam..the shiny metal is the micro switch lever..so could be that it is failing internally.

Oh and adjusting the rubber stops won't help much as the latch and switch reacts to the striker locating in the keeper..which it will even if the stops are extended ...just needs more slamming if they are too far out.

Final word. A good spray of “bolt off” and things appear good so far. Oils ain’t oils. We’ll see how we go with a boat load of outback dust next month.

[INter674]

Final final word...a good degrease and light no residue lube has so far worked for me too☺

As noted the design is such that crap will collect on the switch arm and keeper mechanism preventing it working correctly. Adding more oil will only worsen the situation. Mine had lots of oil...but not from me😞

Looks like the bonnet latch/switch is a periodic maintenance item esp if you travel lots off road.

Simple fix😚

There are adjustments on the latches attached to the vehicle, not the bonnet obviously, a bit of guesswork, a couple of goes all good. NOT an easy bonnet to close quiet and easily. I DONT slam, close down easily to the latches semi engage and then with Toyota leap push down hard on the bonnet where the latches are underneath. Works. Cheers
