2011 GMC Sierra will not remote start

Post by kguent01 » Sat Sep 22, 2018 10:12 pm

installed a Idatastart HC1 unit in a 2011 GMC sierra and am using RSAGM10 firmware. All programming completes but cannot get unit to remote start. Door locks work fine. When I try to start I get 4 flashes and vehicle does not even try to crank. According to error code chart is says engine is running but engine is not running. I went over all of my connections and all seem to be fine. Any help is appreciated!

You need to hold the start button down for 2.5 seconds. Pressing it once gives you a query and the lights flash 4 times.
