    Informational PurposesAn informational icon, calling your attention
    Note
    Make the sure vehicle is not in drive state. Plan is still running despite the stop message. Coolant pumps will be audible. Test lasts approximately 10 mins. Coolant pump speeds can be monitored in Service Mode + (see Service Mode Plus), in the CAN Viewer submenu. Idle speed = ~1500 RPM. Test will vary speeds from 3500-6500 RPM and actuate valve between SERIES and PARALLEL. Putting the vehicle into drive state will stop this routine. If speeds hover at 7000 RPM, that means the pumps are air locked; perform vacuum fill again. Continue to add coolant and purge until the coolant level reaches between the NOM and MAX Lines on the bottle. Select "X" at the top right of the window to close once complete.
  9. Inspect the coolant level and top off as necessary.
