IC Bus Ae School Bus: Electrical
Affects IC Bus Ae School Bus · 2014–2015 — about 6 vehicles.
The hazard
On certain school buses, a double battery (24 volt) jump start or electrical load dump could result in an overvoltage condition of the linear power module (LPM) which is used to control the heater/air conditioning blower motor speed. If this were to occur, this overvoltage condition could lead to the LPM overheating, causing smoke, and increase the risk of fire, which could result in injury and/or damage to property. Correction: Dealers will replace the LPM with an upgraded design.
