Summary of change:
'''v3/19769 sent for repair''' (2021-10-26). ECU '''communicates reliably, and no issue with inputs or outputs was found.''' * "fuel injector activated (not for a short time)" ** injector ouputs and all other outputs activate as they should. Tested with test config. '''Most likely the problem is caused by configuration''' * however, more details about the engine and harness are needed so we can give tailored advice related to configuration. See [http://www.vems.hu/files/MembersPage/UnknownFourCyl/v3.3_u019769-A-2021.10.25-VEVOE.vemscfg 2021-10-25.vemscfg Config file] (most likely problematic): ---- '''ECU communicates without any problem with good USB-RS232 adapter''' Most likely cause of any comm-problem is bad '''USB-RS232 adapter, or windows driver''' (or cable or USB port or similar) problem * "sometimes ECU cannot be reached" => with good cable: works 100% reliably * "some values couldn't be read out or implausible" ** perhaps related to USB problem. Otherwise some example vemslog would be interesting, with exact examples.
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
