Pinpoint Test V : The Engine Over-Temperature Warning Indicator Is Never Or Always On

  1. Normal Operation and Fault Conditions 

    See Engine Over-Temperature Warning. REFER to: Instrument Panel Cluster (IPC) - System Operation and Component Description .

    If the engine coolant temperature data or engine overheat indication request messages are missing or invalid for less than 5 seconds, the IPC defaults the engine over-temperature warning indicator or RTT warning indicator to the last indication state (on or off), based upon on the last message received.

    If the engine coolant temperature data or engine overheat indication request messages are missing or invalid for 5 seconds or longer, the IPC defaults the engine over-temperature warning indicator or RTT warning indicator on.
