BECM failure? U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623 and U2624


Hiya,

2 weeks in the past I ‘ve obtained MIL and DTC’s U2603, U2604, U2605, U2606, U2617, U2618, U2619, U2620, U2621, U2622, U2623 and U2624. My 2016 Chevrolet Volt has 30k kilometers, however sadly I introduced it to Europe, to Poland and I’ve no guarantee.

SO I purchased used BECM from ebay with hope that it really works, like in description used means working. I modify it, then reprogram all modules in automobile with SPS to latest software program, together with this BECM. I made take a look at drive 10 kilometers, with out issues. Then obtained i t to charger and an hour later attempt to drive. Once more similar codes, once more similar downside. Rising vary from 0 to max (about 80km) after which all of the sudden 2 km vary.

Do you suppose BECM from ebay was broken or one thing within the automobile might harm it? New module prices about 380$, so I’m afraid I’ll purchase it, change and it’ll break too.

Possibly somebody has any concepts, or comparable experiences?

Thanks all prematurely! Finest regards.
