Circuit Description
When the ignition switch is turned ON, the Engine Con-
trol Module (ECM) will activate the pump relay and run
the in-tank fuel pump. The fuel pump will operate as
long as the engine is cranking or running and the ECM
is receiving ignition reference pulses.
If there are no reference pulses, the ECM will shut off
the fuel pump within 2 seconds after the ignition switch
is turned ON, engine stopped or engine stalled.
Conditions for Setting the DTC
•••••
Current is between 1 ampare and 2 ampares.
(depending on driver condition)
Action Taken When the DTC Sets
•••••
The MIL will illuminate after two consecutive driving
cycles in which the diagnostic runs with the fault ac-
tive.
•••••
The ECM will record operating conditions at the time
the diagnostic fails. This information will be stored in
the Freeze Frame and Failure Records buffers.
•••••
A history DTC is stored.

Test Description
The number(s) below refer to specific step(s) on the
diagnostic table.
1. Euro On-Board Diagnostic (EOBD) System Check
prompts the technician to complete some basic
checks and store the freeze frame and failure
records data on the scan tool if applicable. This
creates an electronic copy of the data taken when
the malfunction occurred. The information is then
stored on the scan tool for later reference.
