Pinpoint Test Al: The Ready To Drive Indicator Or RTT (RECONFIGURABLE Telltale) Indicator Is Never On (HEV (Hybrid Electric Vehicle))

  1. Normal Operation and Fault Conditions 

    See Ready to Drive (HEV). REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

    If the ready to drive indication request message is missing for less than 5 seconds, the IPC defaults the ready to drive indicator or RTT indicator to the last indication state (on or off), based upon the last message received.

    If the ready to drive indication request message is missing for 5 seconds or longer, the IPC defaults the ready to drive indicator or RTT indicator off.
