TACH-cluster replacement-resetting ODO? - Page 2 - Toyota Yaris Forums

MGargano - Here's another idea: Put your old cluster back in (without disconnecting the battery). Drive around for a little while with it in. Then, disconnect the battery, re-install the new one, cross your finger, and power it back up.

I think I'll give this method a shot first. I don't think I need anymore electrical problems at the moment...one thing at a time

I just bought a cluster from ebay and waiting for arrival. For me, I am after with the tach.

Is the odometer reading stays with the ecm or it follows the cluster ecu?

It stays with the cluster ECU. The ECM doesn't store odo data.

Thanks CTScott:

Unfortunately, this did not work. The mileage in the new cluster remained the same after disconnecting the battery

Out of curiosity, when you put your old one back in last night, did it read what it read before the great swap?

Lewis, how about trying the battery disconnected swap (in the name of science) before you return the wrong one?

By the way, last night I was doing some research on the parts that are going to be in the wrecked Yaris that I am picking up on Thursday. It is an 08, built in 08/2007. In the EPC I noticed that there was a bulletin (dated August 2, 2007) attached to the speedometer info. This is the first time that I've run into an attached bulletin when looking up parts. In the bulletin it says:

Eligible Parts
Programmed Digital Odometer replacement part numbers for Toyota and Scion vehicles are listed on the last two pages of this bulletin. Odometers should be ordered to be programmed to read the vehicle’s actual indicated mileage at the time of odometer replacement and must be ordered directly from the listed vendor (Denso or Yazaki)

In the Yaris section at the end it references the following part numbers:
83800-52B70
83800-52C70
83800-52E70
83800-52E80
83800-52E90
83800-52F00
83800-52F10
83800-52L00

Yes

mikenacarato · 08-10-2009, 09:03 PM

dang scott..didnt think to do that! i still havent had my mileage updated. and i tried disconnecting the battery for a few mins and it didnt work.

MGargano · 08-10-2009, 09:56 PM

Then again, I am still waiting for those 3 ohm resistors...

There you go. Abusing your car's electrical systems becomes addictive.

Lol so I'm seeing. I put the OEM cluster back in tonight. How long do you figure I should leave it in?

PS- resistors shipped today.

auxmike · 08-10-2009, 10:37 PM

This is a real cool thread!

I have the scanguage as a tach in my car, but I'd love a real tach too...

If this has any chance of working, I'd say drive around tomorrow and then put the new one back in tomorrow night (with the battery disconnected).

i'm not sure if this would work in any way or not. but my old car if you disconnected the - part of the battery, then turned the key like you were going to turn the car on, and left it in that position for a few minutes it would "reset" the ECU. this is how i got my check engine light to go off before an inspection a few times. maybe resetting it will cause it to recognize the new cluster as what is stored in the ECU's memory from the old cluster. just a shot in the dark, but you never know.

Lewis · 08-11-2009, 06:47 AM

I'd say go for it Mike!

Nothing to fear but fear itself. As we used to joke when I was in the Army- "What could possibly go wrong?"

:-)

Lewis · 08-11-2009, 06:08 PM

correction - it will NOT be me- at least for awhile

junkyard sent cluster that did not have a tach- i guess they figure some folks won't go to the trouble of a return

so the hunt continues- anyone with a lead on a hatch cluster with a tach and abs light- please let me know

what a bummer!

Sodium Duck · 08-11-2009, 06:17 PM

There are so many different threads on this. Can we just combine them all and sticky this since it seems to be such a hot topic?

Also, what kind of cluster would I have to search for to get the one that walterokus used? I like how it's the base model colors and not the orange S model colors.
