The cooling fan issue is likely related to the powertrain control module failure. I don't see a need to hotwire it at this point.
I'm not sure why the problem started with a blowout, but something happened. Here is what the code indicates (right from my manual):
2002 Chrysler Truck PT Cruiser L4-2.4L VIN B
Vehicle ALL Diagnostic Trouble Codes ( DTC ) Testing and Inspection P Code Charts P0601
See pic 1
P0601-PCM INTERNAL CONTROLLER FAILURE
This symptom is diagnosed using the test P0600-PCM FAILURE SPI COMMUNICATIONS.
Ignition key ON.
Internal checksum for software failed, does not match calculated value.
- PCM Internal Or SPI
Now, the directions indicate either a failed PCM or an issue with the SPI (serial peripheral interface). In understandable terms, there could be a break down in communication in the controller area network (CAN). The CAN is a means of communication between all of the modules/computers via a few wires.
When the tire blew out, was there any damage done to the vehicle? If not, the next thing I would try is to scan the can-bus system to see if there is an indication of possible can issues.
Here is a video showing how that is done:
If you still find a P0601 is the only code, there is a good chance the PCM has an internal fault and needs replaced.
Let me know if that helps or if you have other questions.
