Speed sources not working


Recommended Posts

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

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.
