# Service bulletin CSC\-2402

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

The max current threshold in the X4 Control Board has the potential to de\-activate the subject circuit pre\-maturely. The X4 Control Board is the electronic module that controls many of the RV’s systems \(including awnings, leveling, slide\-outs, lights, tank heaters, and others\). The tank heater portion of the system is intended to cut out at 20Amp, but has been observed to cut out as low as 10\-17A. In some instances, especially in colder conditions, it is possible that the tank heater circuit will shut off earlier than intended, and could potentially lead to the tank or icemaker line freezing. The remedy for this incorrect electrical setting is to install an in\-line relay between the X4 board and the high current \(HC\) latch/tank pad and water line.
