SSM 46923 – 2015-2017 Transit – 3.5L and 3.7L Gasoline Engine – Cooling Fans Inoperative Due To Open BJB Fuses F30, F31, and/or F8

Some 2015-2017 Transit vehicles equipped with a 3.5L or 3.7l gasoline engine may exhibit an engine overheat condition or poor A/C cooling due to one or more of the 3 cooling fan fuses being open.

If any one of the Battery Junction Box (BJB) fuses F30, F31, or F8 are open, replace F8 from a 20 amp to a 30 amp fuse (6E5Z-14526-BA), and service the F30 and F31 40 amp fuses (6E5Z-14526-CA) as needed.

The wiring diagram has been updated.

Failure to replace an open F8 with a 30 amp fuse will cause F30 and F31 to open over time.

Claim using causal part 9K499 ifno other root cause is identified.

Use applicable labor ops from section 10 of the SLTS manual for fuse replacement.
