The vehicle has had a front impact. The 4L light stays on and flashes (with beeping). Heard it’s the differential pump and that it’s behind the bumper but I can’t seem to find it!
Also where’s this sensor go? I can’t any where the clip on the back would plug into.
Also I just replaced the cv shaft and actually couldn’t seem to find any hoses to follow (I’m guessing it must come from the top ?)
Thanks In advance

First off, is yours a 3rd gen or a second gen? 2006 was the year we got the first of the 3rd gen models down under.
Separate transfer case lever?

The fact that he mentions a 4L light flashing and beeping suggests it's a third gen, and third gens don't have that "differential pump" - as for the sensor, you'll have to be specific, we don't know what sensor you're referring to.

Thanks. I’ll try reattach photos

Third gen thankyou

That, I think is the "outside" air temp sensor, and as I mentioned earlier, third gens don't have the differential air pump, the front diff on those is always "engaged" because they are full time four wheel drive.

---------------------

I had a quick look at a parts catalogue, that IS the outside temperature sensor and it appears to fit somewhere behind the lower grille - my third gen is at back of the yard and today being Saturday, I'd have to move two vehicles just to get to it, remind me on Monday and I'll see if I can find out exactly where it goes.

Back to the 4L light flashing & beeping - where is the selector knob now? If it's in 4H, STOP driving the vehicle until you can get it sorted.

Essentially you get the beeping and flashing lights when the knob position doesn't match the actual transfer case selection, so if the knob is in anything other than 4L and you're getting the 4L light and a beeping, it means the transfer case could be in 4L and you don't want to be driving on a hard surface in 4L.

Let me clarify that a little, the selector knob has four positions, 4H, 4HL, 4LL and N - the only one that should be used whilst driving on a hard surface is 4H. The 4HL & 4LL positions lock the center differential and driving on a hard surface with the center differential locked can cause transfer case damage.

If the knob is in 4L and the lights flashing, turn the knob back to 4H and see if the flashing/beeping stops, if it does, you'll probably be fine - there's a specific sequence of shift lever, brake pedal & selector knob operation to actually get the transfer case to shift into 4LL, so if someone were, just as an example, fiddling with the knob with engine off, and you then started the car, it shouldn't actually engage 4LL, but it should warn you that the knob position doesn't match the case position.

I agree, 3G, that's ambient temp sensor theres a clip about where your hand is but behind the number plate under the top edge of the bumper, can't see it bumper on, but you can feel for it. Mine came off and was knocking around for a while.

4L and beeping can also be a stuck transfer case position switch or short in the wiring.
Check transfer position switch as Fordem has suggested. Then if that doesn't work, off to a shingle road and run the case thru all positions a few times to exercise the switches.

Just done a check on my car while out and about. Switch in 4H as normal. Ign off, switch to 4HL key on, transfer switches immediately with the usual " transfer case switching" message on dash.
4H ign off, select 4LL ign on, dash message " check transfer switch position" no warning lights or beeping.

I suspect a transfer case switch issue.

Ok great thankyou. What you say makes sense I’m not missing a part somewhere! I did have a look at the transfer case selector just incase not having been able to find the other.
I’m thinking I might take it on some dirt to run it through the various settings to see if it will sought a sticky sensor or something.
the actuator is in an awkward spot to remove if it does need to come out. Cheers

Brilliant thankyiu. I’ll run it through the 4wd setting and see if make a difference. Cheers

It won't be the actuator, more likely the 4L switch, pain to get to but easy enough to change if needed, but still a bit of diagnosis to go thru first before condemning it.

Hey thank you kindly for your assistance. Turns out I had the selector dial in the wrong spot. I thought it was meant to be in neatural. The mechanic didn’t seem to know either after scanning it 😅.
Cheers again

Following your advice input the dial in 4H beeping and lights disappeared. I’d thought it was meant to be in neutral. Now I know. The scan read from the mechanic was a bit of a waste 😂
Thankyou very much appreciated your advise us been great.

You're welcome, glad to hear you got it sorted.
