Read stored/pending/permanent DTCs, decode with 6.0-relevant codes flagged, guarded mode-04 clear (--clear), key live PIDs + battery voltage, and a 6.0 no-start triage checklist. Tested against a CH340 ELM327 v1.5 adapter. Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_016yT89n4zR4qbrySoSiEyZs

6.0 POWER STROKE OBD-II CODE READER (works on any OBD-II vehicle)
|
|
==================================================================
|
|
Built tonight for the CH340/ELM327 adapter. Reads trouble codes, key
|
|
live values, and prints a 6.0 no-start triage. Tested against your
|
|
actual adapter.
|
|
|
|
WHAT YOU GET
|
|
obd_reader.py the tool
|
|
RUN_OBD.bat double-click launcher for Windows (auto-installs pyserial)
|
|
README.txt this file
|
|
|
|
ONE-TIME SETUP ON THE WINDOWS LAPTOP
|
|
1. Install the CH340 driver (you're already doing this) so the adapter
|
|
shows up as "USB-SERIAL CH340 (COMx)" in Device Manager > Ports.
|
|
2. Install Python from https://www.python.org/downloads/
|
|
IMPORTANT: tick "Add Python to PATH" on the first install screen.
|
|
|
|
RUN IT
|
|
Easiest: double-click RUN_OBD.bat
|
|
Manual: open Command Prompt in this folder and run:
|
|
python obd_reader.py
|
|
force a port/baud if needed:
|
|
python obd_reader.py COM5
|
|
python obd_reader.py COM5 9600
|
|
add -v to see the raw ELM327 traffic (for troubleshooting):
|
|
python obd_reader.py COM5 -v
|
|
|
|
ON THE TRUCK
|
|
- Plug the adapter into the OBD port (under the dash, driver side).
|
|
- Turn the key to RUN (not just ACC). Engine off is fine for codes.
|
|
- Run the tool. It reads STORED, PENDING and PERMANENT codes,
|
|
flags no-start suspects, shows battery voltage + key live values,
|
|
then prints the 6.0 triage checklist.
|
|
|
|
SCOPE / HONESTY
|
|
A generic ELM327 reads standard OBD-II: codes, generic PIDs, voltage.
|
|
It does NOT read Ford-enhanced diesel PIDs (ICP, FICM main/sync volts,
|
|
IPR%). Those need FORScan. This covers reading codes + the basics so
|
|
you can triage tonight. For FICM/ICP numbers, measure at the FICM with
|
|
a meter, or get FORScan from the CyanLabs mirror when it's back up.
|
|
|
|
Default baud is 38400 (measured on your adapter). If you get garbage,
|
|
try 9600.
