My 2002 LC100 GXL TD has just developed a problem with the central locking.
It unlocks fine from the remote. BUT, it won't lock from anywhere!
The indicators flash once, as if it has locked, but the relays don't fire.
If I press the remote again, the indicators flash twice and the unlock relays all fire - as per normal.
Also, the key switches on the front doors and the tailgate will unlock everything, but won't lock.
Where do I start looking?

Hi Barry, I've got the same model, no problems on mine but wouldn't it be covered under warranty ?
Regards
Chris

Yes, it is under warranty. I have had additional wiring done fairly recently to add extra battery (Piranha) and run an inverter. Nothing should have interfered with the locking system, and all has been working fine since the wiring changes - only failed yesterday. I guess I'm just looking for something I can do myself instead of losing the vehicle for a day at Toyota.

Could be the batteries, but fault appears with both remotes. Also, I am unable to lock all doors from the drivers armrest switch.

Barry,

Might be worth the trip to Toyota. They probably have a computer they can hook up for this sort of fault diagnosis.

You could spend days trying to track it yourself - unless you had a computer hooked up to the vehicle.Motley

goingplatinumcomau,

Very happy with the Bushtracker. Only collected it couple of months ago, firt big test July/August on trip through NT and Northern Qld.

If you would like more detail, there is an MSN Forum specifically related to Bushtrackers.

Have a look at

stab in the dark here, but the 80 cruisers sometimes had problems with the door/courtasy switches. When all the doors are shut does the dash warning light stay on? The door that wont lock may have the funny switch. To test this theory, tape a paddle pop stick or something like that to the door where the switch strikes and see if it makes any difference.
If you have been getting this rain, it may have effected a switch.

Yes Andrew, I suspected a door switch. But the interior light goes out 30 seconds after the last door shuts (regardless of which one that is), so all must be switching correctly. Also, there is no door-ajar indicator showing on the dash.
Finally, it's not just one door that won't lock - NO door will lock!
Not much rain here in Melbourne, so that's probably not it!

Barry,

Have an 80 series with alarm which operates the remote switching for the central locking. Have had the same problem intermittantly. What I found is that if one door is not quite shut, it would not lock, turns out that it was mainly the rear lift up door. It was strange that our interior light was not staying on to indicate that the door was not shut correctly. However the indicator in the dash was showing that a door was not shut. Did not understand why this dash light come on and not interior light as well. Just something to look at, when happens look through window at dash and see if this warning light is on. (I imagine that 100 series would have them.) Played with switches, going okay now but for how long?, because I don't now what I really did to fix it.

Thanks Dave,
Yes the 100 has an in-dash indicator, but it is not lit.
Stuffed if I know what's happening.
I guess I'll have to book it in at a Toyota dealer.

Barry,

Been thinking about this today, and reckon a relay may be buggered. The central locking may have a 2 way relay, can't think of proper name, similar to type used on h/duty headlight wiring looms. Have you got a manual, that has the circuits on it? Hooroo...

No Bob, I don't have a factory manual. What I need is the wiring diagrams covering the central locking and its relays. If anyone has one that they could photocopy or scan for me - it would be much appreciated.

So this would be a problem with a $70,000 Toyota? Unbelievable, I thought this only happened to Landrovers? Or so we would be led to believe by the B.S. that goes through this site.

My mate just bought a 100 GXL auto diesel and the gearbox kacked it after 2400 kms. Repaired under warrenty but again I could believe that anything went wrong with these Toyotas.

Lets face it....all vehicles have problems, it's only the urban myths that say some have much more than others.

Mike,

We usually travel with other LCs, but on our last trip a friend had a Disco. Whenever it hit a harsh hole in the track, all of the hazards would flash until the circuit was reset by removing and replacing a fuse. Eventually, the bumps caused a factory sidestep to fall off - maybe the hazards were trying to warn us.

I've owned three 80 series and one 100 series since about 1990 (TD and petrol, all manual). All were purchased new and after hundreds of thousands of kms, including many desert and outback trips, this is the FIRST warranty item I've ever had! I think that's pretty damn good.
