The following control limits apply: Any help is appreciated. Ignition must be ON. Commanded State The hybrid powertrain control module- HPCM commands the operating mode of the transmission to one of thefollowing states: The hood must remain closed while commanding either Autostartor Autostop with the scan tool. The car was bought from an auction in the US and the history is unknown, it was allegedly operational before it was sent. I believe that has a hybrid battery safety switch under rear bench seat make sure it's on also make sure the 12v battery is fully charged Sent from my SM-N920P using Tapatalk.
When operating in the Autostop mode, the following controllimits apply: Is the high power battery charged? Index Recent Topics Search.
By posting the year, make, model and engine near the beginning of your help request, followed by the symptoms no start, high idle, misfire etc. When the ignition is ON there are no limits to thiscontrol. The battery was already dead, when it arrived.
The Autostart command will not function when the gearselector is in Reverse, Drive, or Manual.
Perform the high voltage disable procedure and repair orreplace damaged high voltage components as specified in theapplicable diagnostic prior using this control.
I think that the HV batteries are empty, but at the moment, unfortunately, this can not be confirmed. What year is this Tahoe? The error codes are 1.
The hybrid powertrain control module HPCM monitors for ahigh voltage present condition after the high voltage contactorrelays have been opened.
