    LMM stand alone codes U0140 and U0121

    These codes may or may not be a problem, the problem is my EFILive V2 is only giving me these codes, my cheapo Autel is giving me engine codes but not these codes so I wonder what's up with that, I resolved the MAP P0108 code, still working on the P0102 MAF

    Awesome conversion, I am SO happy to see you made it through that roll over OK. My donor 08 LMM looks very similar and I often wondered if anyone could have survived....

    LMM stand alone codes U0140 and U0121

    Thanks to all that helped me so far, It seems I have resolved all the issues but for two codes, it looked like the main issue before was the guy whom built my stand alone harness neglected to connect the TCM and ECM "wakeup" pins to ignition, this was causing the U0073 and P2536 and some other...

    Thanks, I think it is time for a new thread as the problem is different than what I started with, as I have resolved the first complaint, Thank you for helping me with this!!!!

    P0218 low fluid?

    You were definitely on to something there, I have connected the "wakeup" pins on both the TCM and ECM to "ignition" and the P2536 code is gone, I am still getting the U0140 and U0121 and still have LOW engine power

    P0218 low fluid?

    I received a message from someone from the EFILive forum saying that the wakeup lead on both the ECM and TCM should be tied to the IGN. leads so we will give that a shot today.

    P0218 low fluid?

    OK that is interesting, there is no connection between ACCESSORY and the stand alone harness, only run (ignition),, battery and start, I see accessory wake-up serial data pin but where do I connect the ACCESSORY lead to the stand alone harness or modules? (EDIT considering the signal should come...

    P0218 low fluid?

    OK I had made a mistake and had pins 10 and 70 on a switched circuit, I have it going directly to the battery now along with pin 77 on the ECM and double checked all grounds etc. So I cleared the codes and went for a test drive twice, once with each TCM and the results are the same, no power...

    Well that at least That is a place to start.

    P0218 low fluid?

    Yep this is starting to get annoying, the TCM came in today and same thing, well one thing I noticed is the first time I cleared the codes I had a large number of ECM codes starting with P0102, the second time I cleared the codes I get the usual U0140, this is defiantly set to "not reported, no...

    P0218 low fluid?

    I have no idea if it has GMLAN, it has a serial communications link between the DLC, ECM, TCM and TCCM, I have jumped it at the glow plug controller (and have tried it with the controller in place), the guy that made the stand alone harness eliminated all the rest, I can read and write...

    TCM tuning

    So I should change the speedo info in the ECM only and just leave the TCM completely alone for now yes?

    TCM tuning

    I have a some questions about TCM tuning. I have several codes coming in as read on my EFIlive V2 ( U0073, U0121, U0140, P0880, P2536, P0218) at this point I suspect a bad TCM and am waiting for one to arrive. All the codes are reported by the programmer as TCM codes, So the question is...

    P0218 low fluid?

    Thanks but there is no EBCM or BCM so the code should not be there

    P0218 low fluid?

    Took it out for a little test drive and came back with a whole pile of codes, U0073, U0121, U0140, P0880, P2536, P0218. I am just going to have to wait until the TCM gets here on Tue, (I hope)

    P0218 low fluid?

    Well I was also getting a P0090 FPR open and a U0073 communications bus off, I finally dug down far enough in the engine to repair the open harness to the FPR and now the only codes I see are U0140 and U0121 which have to do with BCM and traction control, I have U0140 set to "not reporting, no...

    P0218 low fluid?

    Not yet, still waiting for the TCM to get here

    P0218 low fluid?

    Not terribly expensive but could not use it for anything but a reference then toss it away, someday somebody might have the pan off of a transmission and simply give me the measurement from the bottom of the tube to the tip of the dipstick.
