Part 2
Conditions for Running the DTC
Voltage supplied to the module is in the normal operating voltage range of 9 - 16 volts.
DTCs B1327, B1328, U1300, U1301, U1305 are not set as current.
The vehicle power mode requires serial data communication to occur.
Conditions for Setting the DTC
A message containing a critical operating parameter has not been received within the last 5 seconds after establishing class 2 serial data communication.
Action Taken When the DTC Sets
The module uses a default value for the missing parameter.
Conditions for Clearing the DTC
A current DTC clears when the malfunction is no longer present.
A history DTC clears when the module ignition cycle counter reaches the reset threshold, without a repeat of the malfunction.
Diagnostic Aids
When a malfunction such as an open fuse to a module occurs while modules are communicating, a DTC U1001-1254 Loss of XXX Communications is
set current. When the modules stop communicating the current DTC U1001-1254 Loss of XXX Communications is cleared but the history DTC remains.
When the modules begin to communicate again, the module with the open fuse will not be learned by the other modules so U1000 or U1255 is set
current by the other modules. If the malfunction occurs when the modules are not communicating, only U1000 or U1255 is set.
