PCM gave up, bought a new one. Now the nightmare begins,
does not succeed in programming VIN, meter reading and
SKIM with tools for $4000.
Solution: ??
Build your own (working) system, but how?
The car refuses to start due to the wrong SKIM / SKREEM code.
The Car Hacker’s Handbook, Craig Smith , the third parties
reported do not cover my needs.
( ... ols-trade/ )
Let's start by creating something that causes the engine to run.
Start with what?
I have been working with electronics for the past 55 years.
No problem with CAD one or more PCBs.
One or more CPUs of any kind, memories and I / O ports,
programs and schedules depending on the sensors.

The car: Chrysler voyager 2006, 2.4L, gasoline, manual.
-VIN: 1A8GYN2B76Y129620
-Calibration ID: 05094169AC
-Calibration Verification Number: A51D7CEF
-mileage: 85000 mile
-PCM: P0594169AC replaced with P05187626AA
-SKREEM: P04727338AE (5WY7227E) pincode: 4675
Suggestions, ideas, program writing, solutions, etc. are welcome.
