Odometer problems

[SinIC]

Hi ladies and gentlemen!

I have a problem with my odometer.

The car: 91` 240 SX A/T transmission.

The problem occured some time ago. It just stopped working. Then suddenly it start working again for a couple of days, before it stopped again. Havent worked since. This problem revolves both odometer and tripmeter. Speedometer works as normally.

I`ve searched most of the forums and on the internet, but I can`t figure out what the problem could be.

So, question for you people: Could anyone give me any hint or an explenation of where I could begin troubleshooting?

I`ve read of a loose connector on the transmission that might be the problem. Any guess?

Any replies are mostly welcome.

Regards SinIC

If your speedo works it is not the trans connector thats the problem. Your problem lies in the cluster itself. You need to replace the odometer portion of it.

[SinIC]

And you are absolutely sure of this?

If so, do I have to order parts from US or Japan, or can I use any parts from the european 200 SX (s13) wich shows the miles in kilometers.

Thanks for reply btw!

[NISTECH]

I am not sure of anything without putting my hands on the car to check it myself. But I have replaced countless odometer because of the problem you are desribing and it fixed all of them.

where was your car first sold? that is where you need to get the parts for it.

[SinIC]

My car was sold in Texas somewhere. A guy who lived there brought it back to Norway after living there for some years. Then I bought it.

Anyway, I`ll check with my local Nissan dealer. They have a mechanic there who has been very helpfull to me. Maybe he knows what to do.

Prolly just end up with ordering a new odometer from Japan.

Thanks!

If your speedo registers in MPH you need to get and odo that registers miles not kilo

[SinIC]

Speedo registers both MPH and KMH. Can switch between them. But my odometer registers miles.

[wangless]

"Speedo registers both MPH and KMH. "

so you have a digital cluster ?

well, on my analog cluster, i had both a usdm odometer and a jdm odometer. i can tell you that if you put the jdm odometer in a usdm cluster, youll get kilometers recorded instead of miles. hope that helps...

[SinIC]

Thanks wangless. I`ll remember that!

And yes, I do have the digital cluster.

[SinIC]

Hmm..

Seems to be one hell of a job to get the odometer out though..

[wangless]

drop the panel under the steering wheel, take out two bolts, remove buttons around the cluster (hazard, headlights, defrost, etc...), take out the plastic trim, three bolts then hold in the cluster. take the whole cluster out, unplug the harnesses...

oh wait... its digital cluster... never took odometer out of a digital... only analog. uhh... well, it should be the same maybe ?... then just start taking apart the cluster, you should be able to figure it out by then...

if not, thats what the forum is made for

[SinIC]

Yep!

I got it out. It was a little tricky..

I have cleaned the connectors and also done as described here: http://www.240sx.org/faq/artic...g.htm

Nothing was wrong with the odometer, so then it has to be the cluster itself, the motor on odometer, or some wiring problems. Right?

[wangless]

ill leave this one up to NISTECH...

[NISTECH]

the mechanical odo is toast. Its the only mechanical part of a digital cluster and it has gone south on ya.

[SinIC]

So then its only the mechanical odo that is toast... OK!

If I replace it with a new one, then it probably would work?

Dumbass thing that i didn`t check if the servo (motor) on the odometer got any power while driving.

What mechanical odometer can i use?

Does it have to be for an 240 sx? Or are they similar to other Nissan type of cars? Like the 200 sx? Anyone know?

[NISTECH]

The 300z Z31 and Maxima U11 had a similar odo but not sure if they would work in the 240 cluster.

[SinIC]

Thanks alot NISTECH.

U guys have helped me much already.

Take a look at this link. http://www.automotiveforums.com/t222706.html

I want to check everything i can before i start ordering.

I have tried to locate this sensor. But I can`t actually find it. Easy to find? Could I get an easy explenation?

Thanks!

[NISTECH]

Your odometer and your speedometer work off that same gear. so if your speedo works that sensor is not your problem.

HOW THE ODOMETER WORKS: A signal is generated in the speed pick up located in the rear tail shaft of the transmission. That signal is sent from the sensor via wires to the speedometer unit. In that unit the signal is converted from an AC sign wave to a digital pulse signal. that signal is sent to the speedometer needle portion of the assembly or digital display portion of the assembly at the same time it is also sent to the mechanical wheel mounted in the same cluster.

As you can see by that description there are only 2 posible causes here either the speedometer is not transmitting the info to the mechanical gear or the mechanical gear is not displaying the information it is recieving by turning the wheels. In all cases like this the problem was the wheels motor was not functioning on the cars I fixed.

[SinIC]

Well! That was one damn nice explanation!! Thanks a bunch!

These motors are not selled individually are they? Guess not...

[SinIC]

And i might aslo mention that the wiper intermittent position doesn`t work either. But i believe that doesn`t have anything to do with it.

[NISTECH]

the odometer assembly is about 2 inches in length by about 1 inch high that includes the motor and everything.You dont need to buy the whole cluster there is a way to set the mileage to match what your car is registering now but its tricky.

[SinIC]

Where can i get the odometer assembly? Got any links or tip of where I can get it?

Will my local Nissan dealer be able to order it? OEM number? Etc..

Lot of questions here... Sorry!

[AHall]

My odometer went out some time ago and I was told that I would have to order the entire cluster as the little motor is not sold separately. If anyone finds a dealer that will sell the motor separately please let me know.

Thanks

[NISTECH]

I cant find a refference on line so I will have to check on tuesday when I go back to work.

[SinIC]

Well. Thanks for all the help! And you specially NISTECH!

I`ll also check with my nissan dealer. Maybe he knows something.

[SinIC]

I have now talked with the Nissan guy here in Norway. He wasn`t sure of the odometer assebly could be ordered seperatly. But what he did promise, is that he would check it out. So I will post back a reply after I`ve heard his comment of this.

And you NISTECH? Any luck?

[wangless]

my advice is... when my odometer went out, i just bought another cluster because i couldnt find just the odometer.

[NISTECH]

I was extreamly busy today and didnt get a chance to look it up I will give it a shot tomorrow though. sorry man.

[SinIC]

Well!

Seems to me that the assembly CAN be ordered individually. Thats what my Nissan dealer told me. But there is a catch. For my part it costs somwhere around 320 to 350 US dollars. And thats for the odometer assembly only!! Too much cash for me!

On the other hand, I believe U guys overthere in America can get it a whole lot cheaper. Cars and parts are extremely expensive here in Norway. Damn country!

My Nissan guy are to send me the part number. Belive I will get it by mail tomorrow I hope.

Any other ideas of what I could do?
