Escape 2WD L4-2.5L Hybrid (2010)
In the event that the data (-) circuit becomes shorted to battery voltage, both the data (+) and data (-) circuits are pulled high (12V) and all
communication capabilities are lost.
CAN Circuit Signal Corruption
Rhythmic oscillations, inductive spikes or random interference can disrupt the network communications. The corruption signal source may be outside
electrical interference such as motors or solenoids or internal interference generated from a module on the network. In some cases, an open in either the
data (+) or data (-) circuit to a network module may cause the module to emit interference on the one circuit which is still connected. The trace shown is
an example of a "sawtooth" pattern transmitted from a module with one open network circuit.
Other corruptions may be present when a module is intermittently powered up and down. The module on power up may initiate communication out of
sync with other modules on the network causing momentary communication outages.
