Power of Green Overview

"Power of Green" utilizes available vehicle data collected through OnStar to establish a history of 12V battery health and determine a Battery Condition. The history is based on Battery voltage, current, and other prognostic-related data, which is collected onboard during every ignition cycle. The current Battery Condition can be accessed for enrolled vehicles via the Dashboard in Techline Connect (TLC). Battery Condition will include a timestamp (date/time) with the OnStar logo if valid.

Battery Condition will be one of the following four statuses:

Green 

• "OnStar monitoring indicated good battery condition."
• No fault detected internal to Battery
• It is unlikely that the Battery will require replacement at this time

Red 

• "Battery replacement recommended."
• SAC001 - Battery Low Cranking Capability Due to Shorted Cell
• Battery testing is NOT required, therefore a print out of the Warranty Code when the battery is replaced for SAC001 is not required.
• Follow service information procedure for Proactive Alert Identifier SAC001

Yellow 

• "Starting and Charging proactive alerts detected. Please consult Service Information to diagnose the concern."
• One of the following:
  • SAC002 - Low Cranking Capability Due to Battery High Resistance
  • SAC003 - Low Cranking Capability Due to Battery Low State of Charge
  • SAC004 - Low Cranking Capability Due to High Resistance in Starter System
  • SAC005 - Low Cranking Capability Due to High Resistance in Battery or Short in Starter System
• Follow service information procedure for appropriate Proactive Alert Identifier

Grey 

• "Not enough data available to determine battery condition."
• One of the following:
  • Vehicle is not enrolled in OnStar Proactive Alerts
  • Inability to contact the Power of Green data service
  • Insufficient recent ignition cycles to make a Red/Yellow/Green determination
• If a Battery issue is suspected, proceed to Battery Inspection/Test

Updated Battery Condition data may be obtained by selecting "Refresh" button next to the timestamp.

Note: Since the Green status is dependent on a history of battery health, the Battery Condition may not update immediately and turn Green if the battery is replaced.

While the vehicle is being serviced, the Battery Condition may change from Green depending on Service actions (e.g. if battery is disconnected or becomes discharged, status may change).
