Normal Operation
WARNING: This page is about a different car, the 2006 Mercury Mariner and 2006 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
If the overtemp warning indicator is illuminated (not flashing), at least 1 of the following temperature related conditions exist:
- the internal combustion engine coolant is overheated.
- the electric motor electronics loop coolant is overheated (Escape Hybrid).
- the failsafe cooling feature is in Mode 1 which means the internal combustion engine is running a limited operating strategy in an attempt to reduce engine temperature.
If the indicator is flashing, the failsafe cooling feature is in Mode 2 which means the internal combustion engine will shut down shortly due to an unresolvable engine overtemp condition. The input to the cluster is a message from the powertrain control module (PCM) over the communication network.
