They check both of the following here in California,

1. Steady idle
2. OBD communications.

 

Update:

I am going to try a new plan of attack.
I am going to hook up a temp OBD 2 wire. I am only going to wire Power, Ground and the 2 wires directly to the ecu. Fresh wire means no chance of anything else interfering.

Any one have any ideas?

I am also going to recheck all my fuses for the millionth time.

Any other ideas?

 

Sorry for not answering your call last night I was doing a range rovers brakes.

Don't know why I forgot of course they test your obd my bad.

 

Did you try the ABS blink test?

 

Pin 8 - alarm
Pin 16 - fuse 3
Pin 13 - airbag
Pin 4 - ground
Pin 5 - ground
Pin 7 - ECU with lead to ABS
Pin 15 - ECU With lead to ABS


You could be onto something here. The comm leads also have jumpers that go to the ABS ECU. They show to be the same color going to pins 13&14 of connector C2084 of the ABS ECU. Try the blink test to see if you can access the ABS ECU.

 

I think the blink test works, I was checking all the wiring and the ABS light started to blink OH:. So I think connection to the ABS brain is ok. Any other ideas? should I still try a direct wire? I have a extra ecu. I tired it but the car wont start with it. I imagine it has to do with the alarm brain.

This truck has to many brains for its own good.

I thought I would post this for a reminder of why I am still trying. This truck is a blast even with stock suspension.

 

When you replaced the ECU, did you try to read it with the scanner? Plug it in and see if it will read. I know it won't start, but if it reads, you can swap ecu's at the shop and have everything re-programmed then.

 

I believe we tried with no luck to read the new ecu...

 

sounds like jumpers it is.....

 

Can I just wire the ecu and power and ground and eliminate the abs for my test?
