ABS indicator

[msvx95]

I am very stumped with the ABS problem I am having.
The indicator light on the dash is lit, but the LED under the passenger seat is not lit.

Here's what I have done so far:

1) Replaced the ABS control module
2) Drove the car over 20mph for at least a minute
3) Checked all fuses and they are good

My question is obviously, what could be wrong that I am not getting the LED light under the seat to flash or light up???

I can only assume from here that the wiring is bad.
I have attached a picture of the ABS connector.
Please if anyone can picture or remember if the connector had all contact pins in everyhole. Mine does not as shown in my pic. Is this standard on the connector or did someone mess with this??

anyone, anyone???????

Echo!!.........echo, echo........

attached is a file showing the pins and connector. Doesn't look to me like every pin is supposed to be there.

do you have the info/data to check voltages & resistance values to see if the right data is getting to the control module?

I'm not sure what you mean by data.......I do not have a multimeter though, but would I just be checking resistance across the corresponding connections from plug to ecu?

No. Judging by the symptoms, you should probably be checking for power and ground to the ABS unit. Unfortunately, the diagram Lee posted seems to be missing the information on the power supply pin. If I had to guess, power to the ABS unit is not supplied by the 3 fuses shown on that page of the schematic, but rather on the adjoining page. I would measure the the resistance between the ground pins and a known good ground, then for voltage between the power pins and ground. Unfortunately, you'll have to guess which pin supplies power, but I would guess it's either 1, 4, 11, 15, 21 or 22.

Ok, I shall try that......So it appears from this chart (which I can't print out correctly ) that the grounds are 10, 20, 34.

Sorry for all the questions......I'm just not the electrical intellect I need to be yet.

[msvx95]

So from the schematic, it looks like the pins that are not used are 3,5,6,8,12,13,16,23,30,31,33

My attached pic of the connector is upside down though, sorry.

I guess that solves one part of my question about the connector in which I thought I was missing pins.
