Central locking issue

[guygreenwood]

Hi all,

I have an annoying problem with my van where sometimes when I lock it with the keyfob, it locks then unlocks straight away and the horn sounds once.
Then it will try to lock and unlock again and the indicators flash every 30 secs or so.

Sometimes it all works just fine.

Any ideas where to start with this ??

That sounds frustrating! Here are some potential starting points to troubleshoot the issue with your van locking and unlocking erratically:

1. Check the key fob battery: A weak battery in the key fob can cause erratic signaling and malfunctioning features like locking and unlocking. Replace the battery with a fresh one and see if the issue persists.

2. Inspect the door sensors and locks: Faulty door sensors or malfunctioning locks can send confusing signals to the car's computer, leading to the observed behavior. Visually inspect the door latches and sensor areas for any visible damage or debris.

3. Consult your vehicle manual: Your car's manual might have specific troubleshooting steps or diagnostics for situations like this. Refer to the relevant sections on keyless entry and locking systems.

4. Visit a mechanic: If the above steps don't resolve the issue, it's recommended to take your van to a qualified mechanic. They can diagnose the problem using specialized tools and expertise and offer repair solutions.

Additional Tips:

Some vehicles have a "valet mode" that might cause similar symptoms. Double-check your manual to see if there's a way to disable it if accidentally activated.
If you have a spare key fob, try using it to see if the problem persists. This can help isolate whether it's a key fob issue or a broader system problem.
Remember, these are just general suggestions, and the specific solution might vary depending on your van's make and model. If the issue seems complex, seeking professional help from a mechanic is always the safest and most reliable option.

OK, an update to this issue.

I've worked out that its the rear door that it thinks is open. I suspect its the actuator, but I can't work out how to remove it. I've undone the bolts and disconnected the upper pull wire, but I can't see how to remove the center handle pull wire at all.

I've searched for a guide on youtube/google, searched through the forums but nowehere mentions how to remove this actuator.

Anyone got any ideas ??

i've sorted this now. Took the handle off the outside to reveal a small screw which when undone allows the handle mechanism to pull out and you can unhook the cable from there.
Ordered a new one so hope this sorts the issue.

Let us know if it does please

So the new locking mechanism didn't help so I took out the loom and checked for breaks again - nothing.

I noticed some green corrosion on one of the plugs that go through the door jam and decided this must be the issue so I spliced all 6 wires from both plugs individually.
THEN I noticed that one of the pins in one of the plugs was bent over - see photo.

FFS this has taken me weeks to sort out. Maybe someone else might have a similar issue and can get some help from this.

Thanks all.
