ACTIA MULTIPLEX SYSTEM (MUX)

Parts may be purchased from MCI Service Parts, Louisville, Kentucky.

Description:MCI is now offering the Actia Multiplex System as an option on 2010 Dmodel coaches, beginning with unit 59587. Themultiplex system increases the harness reliability, decreasing the number of circuits, electrical connectors, terminals,and splices. Actia Multiplex System also features a 7-inch LCD monitor installed in multiple locations based on coachconfiguration for technicians to use for onboard system diagnostics and repair. This Service Bulletin providesillustrations anddescriptions related to the systemcomponents, location, operation, anddiagnostics. For further systeminformation refer to applicable maintenance manual.

Instruments --- OperationThe Local Interconnect Network (LIN)The Local Interconnect Network (LIN) data bus is linked from device to device. Each slave has two LIN connectors and

either can be used to make connection with the LIN harness. For troubleshooting, it should be noted that since the LINharness is “daisy chained” if some slave devices are getting data and others are not, there is likely an open in the harnessjust after the last working device. When a slave gauge does not receive LIN data the gauge needle wags and the built--inwarning light flashes. If the gauge needle is wagging but the warning light is not flashing then the LIN data bus is connectedbut the J1939 data for the gauge is not available.

Figure 49. Starter Diagnostics

ThePMMapplication andMessage center combine to provide systemdiagnostics for the starter.When the start switch ispressed the PMMsenses if the starter output has been energized. If not, the PMMdetermines what input is not correct anddisplays a message on the message center.

Starter Diagnostic Messages programmed into the speedometer include:

S STARTER FAULT --- there is an output fault in the PMMS FRONT MODE SW --- the Front/Rear switch is set to REARS REAR RUN SW --- the Rear Run switch is set to REARS TURN ON IGN --- the DMS is in the OFF or ACC positionS SELECT NEUTRAL --- the neutral signal is not detectedS ENGINE RUNNING --- engine RPM is detected > 400 (engine already running)S WAIT TO START --- the engine is not ready to attempt starting.

5 Right Turn

6 Spare (4)

Warning icons, while turned on and off via LIN from the speedometer, they are actually controlled by the applicationprogram in the PMM. The icon logic resides in the PMM application program which also controls any audible alarmassociated with the warning light. Icons are not visible until lit. The spares have a circle icon so that it lights during theWarning light diagnostic test.

Diagnostics

Actia Multiplex System Troubleshooting Overview

Truth Tables are used to analyze the application logic and take the place of ladder logic diagrams. They are simple tounderstand and give the same information as a ladder logic diagram. The LCD Diagnostic Display gives the technician asingle location to view inputs andoutputs throughout theentire coach. Rowsare color-coded to help convey the significanceof each row in the logic block. The following example of the variable HighRise will help explain how to read and understandTruth Tables.
