R57Diagnostic socket for INFOCENTER-
DescriptionThis is a dot matrix display with electronicmanagement/calculation and operation and a buzzer for warning signals.The selection/confirmation controls forthe functions displayed by the infocenter are located near the climatecontrol system controls and consist of 3 buttons (+/-/INFO); theSET function control button is located on the left steering columnswitch unit lever.Functions displayed:Engine oil level (histrograms)Service messagesSpeed limit (acoustic warning as well)DateFault signal repetitionOutside temperatureLighting adjustment through histrogramsLanguage selectionDoors checkOperation of inertia switchEngine oil temperature (GTA only)Trip computerThe instrument works with the ignition switchedON.
Functional description The supply for module E63 arrivesdirectly from the battery. (maxifuse J/B1 of B99 ) to pin1 via fuse F10 of junction unit B1 ; the supply controlledby the ignition (INT) reaches pin 3 of the line protected by fuse F4 ofthe additional fuse box B98B . Pin 11 is earthed. The control buttons, incorporated in theclimate control system M70 controls, are connected to pins16, 19 and 20. A serial line also connects module E63 - frompin 13- to the climate control system M70 . The SET button, located in the steeringcolumn switch unit ( H5 connector E) is connected to pin 15. Pins 4, 8, 5 and 9 of instrument E63 areconnected to the switches at the locks of the front doors (connectorC of N50 and N51 ) and the rear doors (connector Bof N55 and N56 ), respectively and signal if any ofthe doors is open. Similarly, the opening of the boot is signalledby switch I11 to pin 6. The signal indicating the operation of theinertia switch I50 reaches pin 10 of E63 . A serial line connects module E63, frompin 7, with speedometer module E10 with this line used to send informationconcerning the warning lights (for the repetition of the signalat the actual INFOCENTER) for the engine oil level, speedometersignal, etc. See E4021 SPEEDOMETER . The engine temperature signal is sent againat pin 17 to module E203234358SeeE4023DASHBOARD CENTRE AUXILIARYEQUIPMENT() . The engine oil pressure signal is sent againat pin 18 to module E303234338SeeE4022CENTRE INSTRUMENT (CHECK) . Module E63 has its own diagnosticserial line - from pins 2 and 12 - which is connected to a specificdiagnostic socket, R57 .
