Diagnostic Trouble Code (DTC) Definition
and connector information.
The following DTC relates to the vacuum system:
Inspection and Verification
•
DTC C1777 Vacuum Pressure Circuit Failure
Refer to
— The interface adapter assembly (IAA) module
uses the vacuum pressure sensor to monitor
the pressure in the vacuum system. The
normal operating pressure of the vacuum
system is 26-34 kPa (3.8-4.9 psia). The
normal range of the vacuum pressure sensor
is 15-105 kPa (2.2-15.2 psia). The IAA
module sets DTC C1777 if the brake pedal
has not been pressed for 30 seconds and the
vacuum pressure is less than 15 kPa (2.2 psia)
or if the brake pedal has not been pressed and
the vacuum pump has run continuously for
more than five minutes. DTC C1777 is also
set if the vacuum pressure is greater than 93.5
kPa (13.6 psia) and the vacuum pump has run
continuously for more than five minutes. If
this occurs, the IAA module operates the
vacuum pump at limited operating strategy
(LOS) mode defined as six seconds every two
minutes, and for a preset time each time the
brake pedal is depressed or released.
