What should i look for when getting engine codes u0121,u0101,u0155,u0073,u0100. plus all lights on clusters on. some times car only goes 5mph till i shut off and restart.


All these " U " codes are communication issues amongst modules. These modules communicate on bus wiring from one to another. You have a communication issue with one or more modules. You will most likely have to have the vehicle proffessionaly scanned with a vehicle scan tool to be able to identify the source of this communication issue. You may have a bad module/wiring/power/ground issue to be repaired

How do fix TCM and ECM


Hello, It is not just a simple answer to your question of fixing tcm and ecm Depending on the issue you with the TCM or ECM you will need all the proper tools and maybe the Mazda software. even if you have all these things, you still need the knowledge on how to use them or you can damage the ECM TCM very easily. If you have an OBD2 scan tool then you can scan the codes and clear them. The light should go out. If it comes back on then scan the codes again and post them here. I will tell you what you need to do. The code will start with a letter then four numbers, like this P0301 or P1611 or something like that. I am here to help, -Tim

What do these codes U0100, U0155, U0101 and P2187 mean for my mazda?


U0100 - Lost Communication with ECM/PCM "A"
U0155 - Lost Communication with Instrument Panel Cluster (IPC) Control Module
U0101 - Lost Communication with TCM
All of them are Geniric Codes 4 Mazda, I would say who ever was working on the car last, posobly forgot or missted 1 or 2 connection
plugs along the way near the last repairs. So just trace yr last steps 2 see if ther any unpluged connectors, cos looks like they all are part of same chane in that line.
P2187 - Sys To Lean at the idle Bank 1
Hope that helpes you. Good luck.
