Make: International
Engine: MaxxForce DT (2010 & Newer)
PID: N/A
SPN: 729
FMI: 18
Description: IAH monitor fault: lack of heat in the intake manifold
Troubleshooting:
The Intake Air Heater Control (IAHC) warms the incoming air supply prior to cranking to aid
cold engine starting during warm-up. The IAH system also helps load the engine during a
Diesel Particulate Filter (DPF) regeneration.
Probable causes:
1) Defective wiring
2) Defective relay
3) Open circuit on heating element
