False Buick MIL

Owners of 2014 Buick Enclave FWD vehicles may comment about the MIL on. Technicians may find DTC P069E set in memory.

This may be caused by some fuel pump flow control modules being produced that will function as intended but may create a false MIL lamp.

Replace the fuel pump flow control module. The affected modules were made in 2013. Refer to the VIN label to check the Julian date.

In the example shown here, note the highlighted number. The numeral 3 indicates that the vehicle was produced in 2013. The 260 seen here is the sequential day of the year. The affected population is dated 115 to 228, parts dates outside of this range should be considered good.
