How do I get code p0601 out.have done everything unhooked battery,cleaned all ground car will not start.changed battery a cam scencor

code p 0601 refers to engine control module ( ECM) memory check sum error ===causes--- ECM
to correctly reset an ECM use a scan tool for the job
removing the battery can corrupt the CPU program of the ecm and while if can work in some instances there are many cases where other problems are created by that method
Try substituting a know good ECM if the reset fails

Multiple engine codes 2001 chry town and country engine barely runs it surges, spits and sputters the main codes are po601 and po206

P0601 : ECM internal Failure.
it said that the ECM is unable to communicate with the SPI line.
probable causes:
shorted input sensor
shorted electrical circut
failed ECM .
------------ P0601 is Internal Controller Failure- Common repair is Install new PCM and program it. -------- The other code is related, Best thing to do, so you do not replace every part by trial and error, in this case have a pro hood up his computer and he can break it down to the main cause to fix that code, and the other one that is related.

Check Engine light, had it diagnosed, PO601, Internal Controller Failure

Basically that means that there is an interal fault in the Powertrain Control Module (PCM). There have been many reported PCM failures on Chrysler/Dodge products although it is possible for this to happen on any vehicle. In Dodge/Chrysler products, a P0601 trouble code means that a serial communication failed inside the computer at least 6 times. goodluck
