2 Amigos?

[Chuck]

I replaced the shuttle valve switch and rewired around the circuit board and got rid of these 2 codes:
035:Rear Right out valve open circuit
114:Shuttle Valve Electric Failure

Still have 021:Engine PWM signal bad+

and oddly the HDC and TC lights stay on but the ABS light is off now

Any suggestions on where to look next?

Hmm strange, when the sensor fails you get all three. Has it been scanned? By the an autologic scanner? I should tell you what is going on. Hope this helps..

check the hdc switch make sure it isnt on.

rave says those two lights is a engine input signal fault/throttle stuck wide open.

My 99 would get a couple of amigos for no TPS signal. Looking at live data, the ECM could see TPS just fine, but the SLABS could not. It turns out the ECM had a green spot where the signal left to go to the SLABS. I gave the ECM a good scrubbing a la ptschram style (actually the second or third time I cleaned it because I guess I missed spots) and it fixed the problem.

Thanks for input, tonight I will check the rave to see which plug has the ecm to slabs wire and start checking there.

So far no luck.
I checked continuity of the wires in question for this fault and cleaned the contacts on ecm and slabs. i guess next step is to find a known good slabs and swap it to see if the code goes away.

If it is like ours, the 3 have been on so long that one of the bulbs burned out!

Mine was actually INSIDE the ECM that was corroded. The wires tested good (first thing I checked too). Then I swapped the SLABS from my 03 and that didn't fix it. Then I opened the ECM. I think there was some crap under a shinny metal shield on the back/inside of the connector and some more green on the circuit boards themselves.

 

[Chuck]

thanks again. i will try that next.

 

[Chuck]

how green was your ecm connections? mine don't appear to be bad, but i scrubbed them top and bottom anyway.

didn't resolve code

you mentioned it took a few tries, i may give it another shot tommorrow.

 

[jafir]

Under the shield, the back side of the connections, were quite green and crusty. The board itself just had some spots, didn't look too bad, but the chips and stuff have very tiny connections that could easily get bridged.

 

[Chuck]

base on your explanation, mine wasn't corroded at all. the part under the shield looked brand new.

I was hoping that would be the issue. the land rover experience is being slightly expensive as of late.

Anyone have a working slabs without ace or sls in the kansas city area that is interested in an experiment?

I had the Two Amigos problem for a while. Then I got a code on the RR wheel sensor. I replaced it with a used one and no more Two Amigos.
