My understanding is that the EDC ECU is accessible from INPA from the 20-pin port. Is that not the case?
If the shocks are too old or damaged then i will send them to be refurbished. For now i need to find if there is just a broken wire or similar that i can fix. In order to do this i need to first rear error codes (others here in US have used regular code readers with 20-pin to do this for EDC errors) and then test each shock electrically while still in the car.
This is the connector i have and will use. Are you saying that it will not access the EDC module?
