1999 International Harvester 3800 problems

What is wrong

On certain school buses and truck model vehicles manufactured between february 28, 1999, through april 5, 2004, the anti-lock brake system electronic control unit (ecu) may misinterpret a corrupt wheel speed signal.

Risk

The corrupt wheel speed signals may improperly activate the ABS, instead of deactivating the ABS. This may result in the driver experiencing a hard pedal feel and a decrease in deceleration at the end of the stop, resulting in extended stopping distances which could cause a vehicle crash, possibly resulting in property damage, personal injury, or death.

Remedy

International will notify its customers and inspect and repair the affected vehicles free of charge. The recall began august 1, 2004. Owners who take their vehicles to an authorized dealer on an agreed upon service date and do not receive the free remedy within a reasonable time should contact international customer service at 1‑800‑327‑4236.
