My Ignition Broke!

If I recall correctly, it releases the steering wheel and shifter once the key is inserted and rotated.
Thanks @BILT4ME
But my truck is manual transmission, then I preume it's for the steering wheel.
Does it release when like in the picture or when it is depressed ?

In the position it's in, it will be locked (de-energized).
When you turn the key, it energizes the solenoid and it pulls the pin to unlock the steering wheel.

Umm, are you sure the steering lock is electric? The manual shows it's mechanical, and works without a battery in the vehicle

No. Doing it from memory.
 
Good day to all.
Im in a similar boat with an issue in the tumbler.
Just a quick :banana: question :
What is the function of the "Key Interlock Soleniod" ?
Thanks.

That switch(not solenoid) is used for 'illumination control' and also to help keep you from locking the doors with the keys in the ignition when you have power locks.

Nothing to do with the steering interlock, it is purely mechanical.

It looked like a switch to me, but the FSM referred to it as “….solenoid” so to avoid confusion I followed the FSM's naming.
Can you elaborate further regarding “illumination control).

I presume that perhaps the steering column upper braket comes wired for this option and the model dictates if there some sort of "Illumination Control" or not.

Anyway I managed to fix the tumbler temporarily so I can turn on the engine.
I had to remove these components :oops:, because that square metal part (bottom right) was preventing the key from going in smoothly & sometimes jamming.

I then made a slight modification to the key cylinder to keep the switch "energized", while waiting for a new ignition switch coming in the post from Dubai :rolleyes:

I took her for a spin and everything was normal, so far.
Thanks for your feedback.

Additional photos to assist in how it all goes together:

The Key Interlock Solenoid Tells the Shift Lock Control ECU that the key is in and it will release the shift interlock solenoid. The stop light switch must also be activated in order for the Shift Lock solenoid to release the shifter.

In your case with a manual transmission, you may want to access the repair manuals above in the Resources Section for the one that best fits your truck. There may be a clutch interlock switch associated with your truck (just a guess).

In an auto the solenoid does nothing other than keep you from turning the ignition off unless the shifter is in park, it is on the front of the cylinder casting I believe.

If yours is a manual it does not have it.

The switch(that you pictured) let's the central locking controller and light controller know that there is a key in the ignition.

For central locking it will automatically un lock the doors when you try to lock then if the key is in the ignition.

If illumination it is used to to cancel the timer for the key illumination light, and i believe set the sun roof open warning when you leave it open/key off and open the door.

l have not looked very closely in the illumination stiff in years so that is fuzzy, but can double check later.

Good simple fix to get it running!

What market and model of 80 do you have? Your on the right track to download the correct manual.


Keep us in the loop as you diagnose

Tkx., no need to double check anything unless you really want to know more.
My babe is a 1997 GX-R
FZJ80L- GCMNUV
VIN : JTB11UJ83V5013283
Trans : H151F
Axle : K294
Mileage : 688, 550 Km (single owner), I hope I can reach 1M km's in my lifetime. According to my calculations I still need to keep driving for the next 13 years , i.e. till I turn 77 :rofl: doing at least 23K Km/yr, otherwise my daughter will do that milestone.

I have no key illumination light, no sun/moon roof, no auto-central lock (manual center lock only), no automatic headlight thingy, no cruise control, no vanity light, no diff lock, no OBD, etc.
I can lock the truck from the outside with key in igntion & with engine running also.

Driving as is for a few days now and everything running well, headlights, turn signals, brake lights, hazard, cabin lights, reverse light, etc.

The buzzers for 120 Km/hr, seat belts & key in ignition were disconnected a week after I bought her.

I do not have the exact FSM for my model, but have used various FSM's for different models over the years.

I did a search on some FSM's on the resources portal and managed to dig out the following :
KILM_1.webp

KILM_2.webp

KILM_3.webp

KILM_4.webp

I'm under the impression that this switch is part of the standard harness the comes with all steering wheels for various models, I guess it makes sense (more economical) during manufacturing & assembly of steering columns. Whatever is connected to that switch depends on the options/accessories avaialble in any partciular model.

The collective intellgence of this group is a treasure, thanks to all.

Last Update :
Got my new key cylinder from Dubai, 3 days after it was delivered to the shipper (thought, with all the craziness in the world these days, it would take much longer than that).

The very pleasent surprise is that the new keys that came with the new key cylinder were exactly the same as the old keys, have the same number, turn the ignition On and also open all the doors :cool:

When I placed the order from PS I did not specify the key number I had, how did they know ?

When I dug in to remove the old key cylinder, I removed both the Upper & lower Column covers, but when digging in the to instal the new key cylinder I opted not to remove them as it is slightly a hassle to align both with 3 metal screws & 2 plastic screws (upside down) and I managed to remove & reinstal the 2 dashbaord segments without doing so.
If you're just removeing the key cylinder for whatever reason, much easier to do when leaving those covers as is.

The 1 :banana: mod I did to ensure that the switch was engaed lest it is responsible for something I did not know and to also plug the depression in the key cylinder with a piece of plastic to avoid damaging the pastic switch protrusion or it jamming inside that depression while attempting to remove the old key cylinder.

Old & new Key note the amount of wear & tear on the 29 year old key.
