Great video, Thanks! One of the few times I think the oem diagrams are better then the color ones is GM network diagrams it lays it out much clearer IMO.
thanks for explaining I have maybe the similar issue on my Suburban 2012 , I got these code : P0700 Transmission control system ( MIL Request ) , U0073 Control Module Communication Bus "A" Off , P2635 Fuel Pump "A" Low /Performance from where should I start the solution thanks
There are I believe 2 parts to this video that solved this issue. If you would like to solve it for free watch both parts in this series closely. If you miss any parts watch them again.
@@anthonystewart8532 some of those codes fixed but still some problems not fixed yet the main problem came because of canister and made a big tragedy because all particles close the fuel hoses and made full failuir to the fuel pump and cannot be fixed at all so what I made firstly I requested from the mechanic to clean the canister from all charcoal particles completly from all fuel hoses and even I bought a new one but I didn't install it and I will not cos I dont want this tragedy happen again so I replaced the fuel pump assembly with a new one and also requested to remove the fuel tank and make a full clean of all remaining fuel and the charcaol particles and mud full cleaning the parts I bought it but must be replaced is fuel pressure regulator it the part of evap system it is comes after the canister directly this is the most important part to fill up the tank with fuel so the main problem is when the engine is not getting the fuel those codes will show up so the main problem from the canister must be cleaned perfectly from all charcoal it will remain only a small metal inside it the other codes still need fixing I will change the spark plug and new wires the last fix must clean the gearbox harness cable because I think the rain reaches the cable and need fixing maybe some pins not connect elecricity I only suspect and and also the gearbox need updating firmeware I really don't have much time good luck
I’ve been driving with no abs fuse for 2 days and Today while driving at high speed check engine turn on with codes u0109 and u0073 is this because of no abs fuse?
For the U0101 code, which indicates a loss of communication with the TCM, here are a few things to check: Connections: Make sure all wiring and connectors are secure and not damaged. TCM Check: Confirm that the replacement TCM is installed correctly. Grounds: Ensure all ground connections are solid. Other Codes: Look for additional trouble codes that might give more clues. Software Updates: Make sure the TCM and ECM software are up-to-date. Communication Lines: Inspect the CAN bus for any issues.
@@AlexDai-fx2ss Strange, you if there was a problem with PCM it should read 120ohms, not in the megaohms range.. may want to retest and verify you were on the correct pins/contact..

Did you figure out your problem mine had the same codes

The resistors aren’t “in line” the are “in parallel “ with each other giving 60 ohms
hi boss i got cheavy 2012 6 . 0 u0101 killing me,i checked all wieing tcm ecm i had changed but some code pls can you give some type hint. ZF TCM

Interesting video. How about testing at the fuel pump controller module connector?
Yes, more extensive coming on Part2 of this video, stay tuned!

I have pretty much the same problem with a 2015 savana after engine replacement, the pcm loses connection every few seconds with the abs module.
Try reseating ecm, also check ohms across pin 6 and 14 at obd2 port
It should be 60oms?
@@AlexDai-fx2ss 60 ohms
I checked it’s 61ohm when cold, after the truck run for 20mins, it tested megaohm. Swapped new pcm quickly and tested 60ohms

BMW at the end 😂
2013 Silverado..
I got codes:
P0700
U0073
U0100
Did you fix?
hello dear have an issue in gmc seirra 2012 u0073 is showing how is gonna fix it
If you're in Houston TX we can assist, if not watch this video series or contact a local qualified technician.
@@globalcommerce7654I have a 2015 Chevy Silverado 1500 LTZ Z71 got the U0073 just now
