ECM Reprogramming

NOTE:

DO NOT reprogram a FlexFuel (E85) vehicle while the fuel composition learn function is active. If necessary, drive the vehicle until the scan tool indicates that the fuel composition learn parameter is inactive. Programming with the fuel composition learn active will result in fuel trim DTCs.

If the ECM needs to be reprogrammed, refer to Service Programming System (SPS) .
