We have a 100 series land cruiser that has the t-belt light on and can’t get it off. It’s a warning light on the dash

Hello! My name is Gary.
Welcome to JustAnswer.
I'm reviewing your question now, and will post back with a reply shortly.

Hello there,

Should be something like this:

Switch ignition ON
- Press tripmeter switch and ensure "ODO" is displayed
- Switch ignition OFF
- Press tripmeter switch
- Switch ignition ON
- Press tripmeter switch for 5 seconds
- Release tripmeter switch and press again within 5 seconds
- "15" will be displayed
- Press tripmeter switch for 5 seconds
- Release tripmeter switch
- Ensure "ODO" displayed and light goes out

Hope this helps.

Gary

What happens for you?

Does the trip meter button work for other normal functions?

Does the cluster perspex have a rubber bung covering another switch on the gauge facia?

Gary

That's good.

I've seen the occasional fussy reset.

Have a good day.

Gary

Hi again,

If you are all happy now, please rate my service at your earliest convenience.

Thank you for using Just Answer.

Kind regards

Gary

What happens when you press the tripmeter knob now?

Can you disconnect the negative battery terminal for a few minutes, then reconnect and let me know?

Gary

Did the 15 display when you did the reset sequence?

Are you saying the speedo needle is stuck at 6 o'clock?

I've seen that once, and it's a cluster out job to fix.

Gary

Did the needle swing all the around to 6 straight after you did the reset?

Do you have a Toyota dealer nearby?

Gary

I can't say I've seen one do that.

The needle has a mechanical stop to rest on at 0km.

Sounds like the speedo stepper motor has lost its reference zero calibration.

Whereabouts are you?

I'll see if I can refer you to an instrument repairer.

Gary
