G'day all,

Have a 100 Series Diesel. I had the injectors done and timing belt replaced at 100,000 k's (bittuva habit to change the timing belt on my vehicles at 100,000). 150,000 k's ticked over and the timing belt light has come on on the dash. I understand that this is instigated by speedo rather than some sensor on the actual timing belt status of wear.

I contacted the dealer and they have suggested I book it in and pay to have them turn it off. Can someone advise me if there is a simple way to do so myself (and provide direction)?

I think it's as simple as removing a small rubber gromet looking thingy on the clear plastic face of your speedo. Should be near the reset button. After you remove it, press the small reset button with a toothpick or similar.

Wokred on the Dx 4Runner anyway!

I think you will find the 100 series has a digital odometer and it is programmed into that.
You can reset them through the trip meter.
If you have a fax I can fax the toyota procedure to you other wise it may be a fair bit of timing. When I do my customers I reprogram them for every 100 000 km.
Its easy.
Actually I will type it up on word and then cut and paste it.
Bear with me and as Fatty Vautin says, I'll get back to you shortly.

This is a photo copy of a photo copy so some parts were illegible however if you can understand Toyota you should be right. At least it costs nothing to have a play. I think I have got most of the wording. If I were you I would just reset it to 20 which means 200 000 km.
Best of luck.

Timing Belt Warning Indicator Reset Procedure

The bulletin details the procedure for resetting the timing belt warning indicator.
Please use the information with the following manual.

Publication No. Publication Description

(T – Belt Mode)

(a) Turn ODO/TRIP display screen to ODO, and turn the ignition switch OFF.
(b) While pressing the trip switch, turn the ignition switch ON and hold it for 5 seconds.
(c) Release the trip switch then press the trip switch again within 5 seconds.
(d) Transfer to T-Belt mode. The initial setting value is “15”(0,000km)” is displayed.

Hint:- If the meter has been replaced previously, the displayed value may not be the initial setting value.

Press the trip switch and change the replacement setting value.

Every press of the trip switch adds 10 000 km and the meter reading returns to 10 000 km when 200 000 km is reached. If the switch is not operated for more than 30 seconds, the setting value will not be changed, the display screen turns to ODO and the mode returns to the normal mode.

(b) Check that the display has changed to ODO and that the warning light turns off.

Thanks for that info, 80s. Went down and tried it on the 2 79 series utes, and it works on them too. Not sure if I finished the sequence off properly, but have printed out your(toyota's) instructions for future reference.

Seen it all, Done it all.
Can't remember most of it.

Yeah I agree.
We usually do it for nothing on customers cars.
Its getting the info thats hard as we subscribe to alot of manuals and trade info and nothing has been released yet. Thats why it was a photo copy of a photo copy of a photo copy.
Like they say, its not what you know it who you know.
