service manual lookup request

[joatmon]

In Vibe's without ABS, the vehicle speed sensor in on the tranny. Can someone with a Vibe service manual send me or post up the pic of the actual connector on the tranny mounted vehicle speed sensor? I have the pinout, just not sure which is pin 1. Looking for a diagram like this one (but not this one)tia

odd, the connector on the VSS I have has three pins Do they have a different one just for a 5 speed? I bought a service manual, and somehow stupidly lost Volume two. Here is a pic of the connector, and a side view of the VSS. The white gear is driven by a spiral gear in the differential. Pin 1 is 12V, Pin 2 is ground, pin 3 is output. I want to hook up a scope to pin 3 to characterize the VSS signal so I can try to simulate it to run a replacement cluster up to match the odometer reading in my car, but I don't want to hook up 12V to the output and risk blowing it up. I figure I need to run the input to the cluster at 120 mph for about 23 days non-stop to catch it up

Well, I dunno what the 2-pin is (ABS maybe), but here's the 3-pin that matches your connector. According to the schematic, your pinout info is correct. (1=12v, 2=gnd, 3=output).Maybe this will help too: According to the schematic, the output is a switch to +12v that closes 4 times per shaft revolution. So to see a good waveform on a scope, you might want to put a weak pulldown resistor (100k or so) from the output to ground.

Here's the schematic I mentioned in the previous post. This is for the 5spd:Edit Whoops - attached the wrong VSS schematic at first. (Was one I scanned for jeffgtx)

Thanks for the info!

a pulse train of 140Hz is reading on the speedometer at 120 mph.The top end seems to be about 11 KHz. above that it can't count pulses. if 140 Hz = 120 mph, 11 KHz = roughly 9500 mph. Bet that's the fastest anybody here has had their odometer count. actually timed it though, 50 miles in 64 seconds, equivalent to ~2800 mphSo, the replacement cluster odometer is about 4500. The one in the car is about 91K. Means I have to run the odometer up 86000 miles or so. at 2800 mph that would only take 30.7 hours, but I am not sure what running it that fast for 30 hours straight would do to the speedometer meter movement. However, if I run it at a tolerable 120 mph, it will take 30 days. I think tomorrow I will see if the odometer still counts if I have the speedometer meter movement disconnected, then I would feel better about running it really fastedit 10:10 EDT - now at 40K miles, so roughly 35 K miles in 14 hours. Running it at about 8KHz with speedometer disabled

86,000 miles in two days! Your fancy schmancy turbo superrcharged cars have nothing on mine.I really like it.

Wow!So is that GIF old/new clusters?

[joatmon]

yes, two pics taken four minutes apart.my full cluster shots turned out a little blurrythe red gauges play hell with my camera's autofocus, but visually, that is about how much sharper the newer cluster looks (to me anyway) compared to the 2003.here are the two full cluster shots

Hmmmm... methinks this looks like a How-To is going to be in order - yes?

[GMJAP]

Glad to hear you got it all working! Good work Your pics really show how much better (IMO anyway) the new gauges are.I test drove a 2004 Matrix when I was car shopping. The new cluster was a big plus in favor of the Vibe!(Toyota didn't change to the new cluster until the 2005 model. They didn't have an 05 Matrix brochure yet when I was looking, and the salesguy didn't know they had changed it. Their loss, my gain )EDIT On second glance, where did you get the "new" cluster? My warning lights are in different places......Weirdness.

it's a 2004 Vibe cluster I got off ebay months ago and just recently got motivated to deal with the odometer issue.In the 2005, you got more idiot lights, and I think even a second connector for the signals to drive them, so maybe they moved them around a bit to fit in the new onesNot sure I can do up a reproduceable how to. I took a power supply from a dead PC to get 12V, and connected pins 1 and 21 to 12V, 20 and 40 to GND, and on pin 18 I fed in square wave from a signal generator I borrowed from work (referenced to the same ground) Messed with the frequency to get the desired result, and let it run for a long time. I used wire wrap wire and a wire wrap tool to put wires on the pins of the cluster connector.I suppose instead of a signal generator, you could use the serial port from a computer. SInce the data out of a PC serial port is alternated between +12V and -12V, you'd have to use a diode or something to cut off the -12V half of the signal. Then you'd have to figure out the right baud rate and character string to send to the port to get the desired pulse train. For example, at 300 baud N81, a bunch of capital U's would have a binary string of 01010101, , so roughly 150 Hz, which would be ~ 120-125 mph on a base cluster. I had a signal generator with a frequency knob, so I didn't have to mess with that.Either get a replacement cluster with fewer miles on the odometer than the current one and run it up, or get one with any mileage and send it off somewhere to get the odometer set. For example, Mavrik has said he would rather have the all red 2003 cluster, but I think it's a safe assumption that he doesn't want mine if it already has 91K miles on it, I don't know how to run it backwards, and I suppose I could run it till it flips over, but who knows what special surprise might be programed into the cluster for that occaision.If you catch the light off an LCD right, you can see the elements, to see where it can go dark. I checked the owners manual, and it shows the same thing. In the most significant digit of the odometer, one of the segments is missing from the pattern, so the most the odometer could possibly display is 399,999 miles. The trip meter resets at 10,000 miles, so it never uses that digit, only the odometer. It may only be programmed to only display up to 299,999 before it resets to 0, only a lot of time will tell

I took my old cluster, and ran my supersonic odometer rig on it to see what would happen. Was curios to see how high the odometer would count until it rolled over.What I found out was that my assumption was wrong. The odometer climbed steadily right up to 299,999 miles, and then just stopped counting. The trip meters are still counting, but the odometer hit the max and then sticks there. My assumption that it would roll over was incorrect. Now I have a cluster with 299,999 miles on it, glad it was a "spare" So, do not expect to get 300,000 miles out of these cars, just ain't gonna happen.

WHERE DID YOU GET that really cool instrument cluster? I've looked at this page many times and tried to find it out! Those are pretty bada$$.[MisterHighway]
