2020 Ford Transit

Customers may state they are experiencing one of the following issues:

  • Multiple warning lights on dash
  • No PCM communication
  • No ABS module communication
  • No crank/no start

Some 2020 Transit vehicles may exhibit an open master fuse in the high current battery junction box (Figure 1). This junction box is located just behind the battery, underneath the driver’s seat.

The master fuses were not serviceable previously, requiring the entire junction box to be replaced. The master fuses are now available as a separate service part.

For master fuses F9 (500A), F10 (300A), F11 (250A) and F12 (150A), use service part number LJ8Z-14526-C.

For master fuses F1 (125A), F2 (80A), F3 (150A) and F6 (150A), use service part number LJ8Z-14526-D.

Tighten M8 nuts to 12 +/- 1.8 Nm (106 +/- 16 lb.-in.). Tighten M5 nuts to 5.4 +/- 0.9 Nm (48 +/- 8 lb.-in.).

Through warranty analysis and component testing, it has been confirmed that filling the vehicle cooling system with any water other than distilled water can lead to coolant leakage through the water pump mechanical seal. If “tap or well” water is added to the cooling system to dilute concentrated coolant, hard particulates and minerals that may be present in most “tap or well” water will build up between the water pump mechanical seal faces as the coolant mixture passes through the mechanical seal and evaporates by design. The harder (poorer the quality) the tap or well water, the more likely the pump is to develop a leak.
