Here we have swapped a used ECU on 2006 Dodge Charger. And now we will use LAUNCH X431 PRO3+ Tablet to program the VIN and the ECU so the anti-theft light on car would disappear.
After swapping the ECU,
Scan the whole system, and topology will show us some error codes.
Select PCM that has the error code about immobilizer.
Select
Special Function>>Check VIN>>
Write new VIN.
Exit all functions and read VIN number again.
VIN is changed and the PCM error code disappears.
Continue to clear all codes.
Car starts.
Done! That’s how to program used ecu on 2006 Dodge Charger using LAUNCH X431 PRO3+ Diagnostic Tablet.
