What's wrong?

The electric fuel heater on 2017-2021 Ic Bus Ce and Cesb buses is built into the diesel fuel module on Cummins B6.7 engines with fuel module option FS90301 or FS90453. Its normal job is to add heat to the fuel path in cold conditions so diesel fuel keeps moving through the module and into the engine.

In this recall, the heater develops excessive electrical heat inside the fuel module. That heat melts plastic in the fuel heater. Once the plastic melts, the heater area becomes a fire source, and the fuel module problem also leads to engine stalling. The repaired module removes the fuel heater from the fuel module.

There is no warning sign before failure. A driver should not count on a light, noise, smell, or rough running to appear before the heater overheats or the engine stalls.

Who's affected?

Spans the Ce and Cesb bus lines across the 2017-2021 model years. Both use the same diesel fuel pre-heater.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific bus is included.

What's the safety risk?

A fire increases the risk of injury, and an engine stall increases the risk of a crash. There is no warning sign before failure, so schedule the recall repair soon and ask the dealer how to handle the bus until service is complete. Repair is free at any franchised Ic Bus dealer.

What should I do?

  1. Check your VIN to confirm your 2017-2021 Ic Bus Ce or Cesb is included in this recall.
  2. Contact a franchised Ic Bus dealer to schedule the free fuel-heater disablement repair that stops the heater from overheating.
  3. Bring the recall notice if you have it, and reference recall number 20V220 when you call.
  4. Ask the dealer to remove power from the fuel heater and cover the wire harness connector as part of the repair.
  5. Schedule the repair before using the bus for routes, because the fuel heater can overheat, catch fire, or stall the engine.

What happens at the repair

At the Ic Bus dealer, a technician disables the electric fuel heater in the fuel module. The work is done by installing a plug in place of the heater or otherwise making the heater non-operable, removing the fuse that supplies power to it, and covering the wire harness connector. The recall repair is free, with parts and labor covered. Cummins has a general reimbursement plan on file for this campaign, so owners who already paid for a related fuel heater repair should contact Cummins customer service with repair documentation to ask about repayment.
