Review on 🔑 Dorman 99161 Keyless Entry Transmitter Replacement for Chevrolet / GMC Models (OE FIX) by Ronald Bleimeyer

Programmed Dorman keyfob, then tried to change keyfob. He removed Dorman's keychain. Did it again to reprogram the Dorman key fob. I used it for maybe 3 attempts and didn't want to try again. It worked but the service light came on. The truck started and had a very bad idle. I checked the code with an OBD2 reader. GOT U0073 raw C073. Codes cleared but still showing the same code but at least the service light is off and sounds good after driving 10 miles. I don't know if this is forever I checked the codes just before programming the fob and there were no codes. Here is the code I got after using it. .U0073 Source Code: C073ECU: Engine Control Unit Status: Constant OBDII: Control Module - Data Bus OffChevrolet: Control Module Communication Bus Off. short circuit to battery; Control module communication bus A Off Short to ground; Control module communication bus A Off Open; ECU HS bus disabled; ECU LS bus disabled
