2000 C70 HT 2.3 ECU/TCU

Post by subzerocarfanatic »

I am still tracing wires trying to find why i'm not getting 12 volts to my injectors or MAF sensor wiring plugs while the key is on. I am up to the ECU area in the wiring harness, I removed the top cover and there is only the ECU and the slot for the TCU is empty, is this normal for my model Volvo, mine is a 2000 Volvo C70 HT 2.3 with the 5 speed manual transmission. Thanks for any insight anyone can give.

My ECU appears to be the BOSCH H6.2, Is that what comes stock i n my car, just wondering because I want to eliminate all possible issues, was thinking if it was ever changed out for whatever reason that the used ETM built by XemodeX might no sync up with my car if it has been switched at some point, but it did run and drive when i bought it, just with issues.
