Speed sources not working

[muzzytt]

I have digital input 6 as gp speed input. 

I also have wired in 3 abs sensors via a signal divider to reduce the teeth count of the abs. 

 

Note that the speed gp input at di6 used to work no issues prior and so did the 2 abs inputs I had without the signal dividers in place. 

 

I had the car on stands so I decide to check and nothing on the 3 abs sensors in di2 di2 and di4

Or the gp speed input on di6. 

I check the status and it shows off on all 4 even though I'm sure they are all supposed to be on. 

 

The speedo on the dash is working. 

 

Any ideas why this maybe? 

Cheers Muz

On the inputs that you have the frequency divider connected to you will need the pull-up resistor turned on.  Did you have that set?

[muzzytt]

Yep tried that. 

My Di 6 is unchanged so should work. 

 

I wired abs at the abs ecu like you suggested using both + - 

Still doesn't explain why the gp speed input doesn't work

Here's my latest file

If you go to (F12) runtimes and then to the digital tab do you see a Frequency reading on any of those channels?

[muzzytt]

I checked the frequency and nothing at all

[muzzytt]

Double checked all show 0.

I tried turning all the abs inputs off leaving di6 gp speed on still nothing

That would indicate the ECU is seeing no signal. Next step will be to check for a signal / frequency at the input to the ECU.

You can test the Di inputs by setting them up as a GP input and then pulling the signal high or low (depending on pullup off or on)  and seeing if you get them going active.

I'll give that a try tonight. 

 

Just weird that Di 6 that was working before and hasn't been touched is also affected.
