2009 GMC Yukon hybrid no crank no start.
Everything Electrical comes on in the instrument cluster lights, gauges, etc. No security or theft light is on.
Pulled vehicle into bay and ran dtcs only found Ecm P0315, Ebcm C0561, serial data gateway module B1325, and in Pscm u0293. . Also i know at one point a P1A1F was stored in Hybrid powertrain control module. Tested battery on this vehicle and it is extremely weak failed a battery test. I’m just not quite sure if I can condemn the vehicle 100% on that. Since vehicle does not have a starter I kind of lost as to where to start.
Also backstory on vehicle another shop replace the transmission BCM and cam shaft sprockets.
