# Service bulletin MI17\-03

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

After the installation of the latest Multiplex system update on US10 X3\-Series coaches, the instrument panel and switches backlighting may stay constantly on due to an output \(J1:4\) on the A44 module sending constant current to the 114A circuit via the 2mph wire. This wire should be connected only for Commuter application and must be removed on coaches. To retain gateway module watchdog timer \(WDT\) function, a new wire must be routed and connected between module A44 output and the Gateway module.
