Jeep was running great, started it up, engine light on, limp mode, throwing P0700 and P0605, TCM ROM error. Does this mean the PPCM is shot? Any secondary tests I can do? Sources for new TCM? Thanks!
What year model and engine?
Have this on file:
P0605 -- Powertrain Control Module Read Only Memory (ROM) Error
P0700 -- Transmission Control System (MIL Request)
First I would confirm you have good 12v power supply and grounds to the PCM & TCM.
