Just wondered if anyone had a good explanation for this one...It went off yesterday when I was hauling some cows to grass. I'm pretty sure it was because I didnt have my copilot adjusted right for the load I had.....but just wanted a better explanation of the code if anyone knows...


Thanks in advance!


Jason

that means you have a code stored in the TCM...

I take it the predator will not go beyond 700 then? Thats the code it gave me...I dont think the predator cleared it either. I tried twice, but I think it just went away after a few startups.

A predator cannot clear a TCM code.


It will show you what it is but not clear it.


A QUADZILLA or BULLYDOG tuner can clear TCM codes.......

the problem is the predator won't communcate with the TCM to see what codes are stored there. i didn't think the quad/bullydog product would either but maybe i'm wrong.

P0700 is the opening to pandoras box. This code states that we have a trans problem ( all 700 codes relate to drivetrain) and you need to read on to find all the related codes. When I say read on, I mean scan further because P0700 only tells you which computer picked up the problem. In this case it is the TCM ( transmission control module).

Thanks a lot guys. This is better than any other helpline! I'm not too worried about my tranny though....Its a complete ATS setup...I know the first couple of shifts were pretty bad b/c I had the copilot set for soft shifts and that didnt work so well towing 15k. The best shifting was after I turned it off and let the truck do its own shifts........



I assumed that all the tuners that stated you could read codes actually gave you specific codes, not just general ones. But, what can you expect from a $350 gadget?http://www.dieselplace.com/forum/smileys/Ermm.gif

<H1>DTC P0700</H1><A name=ss1-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss1-1476908" target="_blank">
<H5>Circuit Description</A></H5>


The malfunction indicator lamp (MIL) request circuit, signals the engine control module (ECM) that the transmission control module (TCM) is requesting MIL illumination.


DTC P0700 is a type A DTC.<A name=ss2-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss2-1476908" target="_blank">
<H5>Conditions for Running the DTC</A></H5>


The engine is running.<A name=ss3-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss3-1476908" target="_blank">
<H5>Conditions for Setting the DTC</A></H5>


The TCM is requesting MIL illumination or the MIL request circuit is shorted to ground.<A name=ss4-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss4-1476908" target="_blank">
<H5>Action Taken When the DTC Sets</A></H5>
<UL =BULLET>
<LI>The control module illuminates the MIL when the diagnostic runs and fails.
<LI>The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame/Failure Records. </LI>[/list]<A name=ss5-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss5-1476908" target="_blank">
<H5>Conditions for Clearing the DTC</A></H5>
<UL =BULLET>
<LI>The control module turns OFF the MIL after 3 consecutive ignition cycles that the diagnostic runs and does not fail.
<LI>A current DTC, Last Test Failed, clears when the diagnostic runs and passes.
<LI>A scan tool can clear the code from TCM history. The TCM automatically clears the DTC from TCM history if the vehicle completes 40 warm-up cycles without failure. </LI>[/list]<A name=ss6-1476908><A href="http://service.gm.com/servlets/BlobShtml?ShtmlFile=1476908&amp;psdid=210&amp;evc=sm#ss6-1476908" target="_blank">
<H5>Diagnostic Aids</A></H5>
<UL =BULLET>
<LI>Inspect the wiring for poor electrical connections at the TCM. Inspect for the following conditions:
<UL =SQUARE>
<LI>A bent terminal
<LI>A backed-out terminal
<LI>A damaged terminal
<LI>Poor terminal tension
<LI>A chafed wire
<LI>A broken wire inside the insulation </LI>[/list]
<LI>When diagnosing for an intermittent short or open, massage the wiring harness while watching the test equipment for a change.
<LI>You may have to drive the vehicle in order to experience a condition.</LI>[/list]
