A code P0601 in most cases means the PCM
has gone bad. This is possibly due to a short-circuit inside the PCM. Or, if you
disconnect the wires/connector from the PCM while the battery is still
connected, that may also cause this code.
With a P0601 OBD-II trouble code, the most
common fix is to replace and reprogram the PCM. In a few cases the dealer may be
able to reflash the PCM and get it working. But more than likely the PCM will
need to be replaced and reprogrammed (we recommend you take it to a dealership
for this). The good news is it *may* be covered under your emmissions warranty.
So even if you're out of bumper-to-bumper warranty or powertrain warranty, check
your warranty guide or dealer to see if this is covered.
Other people have reported that they cleared the code only for it to return again and again. Keep in mind that most shops can replace the PCM but not all can program it.

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.
