Fuel Supply Pump Relearn Procedure
The ECM goes through a fuel supply pump learn
procedure to fine tune the current supplied to the fuel
rail pressure (FRP) regulator. This learning process in
only performed when the engine is idling.
1. Install the scan tool.
2. Turn ON the ignition, with the engine OFF.
3. Command the Supply Pump Learn Reset with the scan tool.
4. Observe the Supply Pump Status parameter with the scan tool. Confirm the scan tool indicates Not
Learn.
5. Start the engine and let idle until engine coolant temperature (ECT) reads 149°F (65°C) or highe
r
while observing Supply Pump Status parameter
with the scant tool. The scan tool changes status
Not Learn > Learning > Learned.
6. If the ECM has correctly learned the fuel supply pump current adjustment, the Supply Pump Status
parameter on the scan tool will repeatedly indicate
Learning and Learned.
