419-10-10 Multifunction Electronic Modules 419-10-10 DESCRIPTION AND OPERATION receives the cable-transmitted signal from the switch and forwards it on the CAN bus to the door module of the front passenger's door, which then moves the window glass to the corresponding position. The rear doors are each connected via a LIN bus to the door modules of the front doors. The disabling switch in the switch panel on the driver's door can be used to disable the window regulator switches in the rear doors. Speed control The BCM acts as the provider of the signals of the speed control system. The signals which come from the switch unit in the steering wheel are converted to CAN and sent on to the PCM via the HS CAN bus. The PCM then adjusts the power output of the engine to maintain the selected vehicle speed. Brake fluid level If the brake fluid level is normal the brake fluid level switch is closed and sends a ground signal via cable to the BCM. If the brake fluid level is below the threshold and the level switch opens for more than two seconds then the BCM generates a CAN signal which it sends to the instrument cluster. Power management The power management system offers various modes which can be used in different situations to ensure an effective power supply to individual modules. The power management function is integrated in the BCM. Four different vehicle modes are used depending on the operating status of the vehicle: Factory mode: ‡ Factory mode is activated while the vehicle is in production. In this mode, power supply is reduced to a minimum by switching off relays. Once the vehicle leaves the factory the factory mode is deactivated, and transport mode is activated instead. Transport mode: ‡ Transport mode is activated while the vehicle is en route from the factory to the dealer. In this mode, the vehicle can be driven without any adverse effects on vehicle safety. ‡ Individual modules and electrical systems (e.g. anti-theft alarm system, clock and remote control) are deactivated. ‡ This ensures that the battery is sufficiently charged when the vehicle is handed over to the customer. If the engine is started while the vehicle is in transport mode then the transport mode is temporarily suspended. It is reactivated once the ignition is switched off. Transport mode must be deactivated by the dealer. To do this, the dealer needs to press the brake five times and operate the hazard warning lights switch twice within the space of 10 seconds. When the transport mode is deactivated the BCM automatically changes into normal mode. Normal mode: ‡ The full functionality of all electrical systems is available in normal mode. Crash mode: ‡ Crash mode is activated as soon as the restraints control module (RCM) registers a sufficiently severe vehicle impact. ‡ The vehicle is then centrally unlocked if it was locked at the time of the crash. ‡ In addition the hazard warning lights are activated. ‡ Crash mode is deactivated if the ignition key is turned to position "0" and then back to position "II" after at least 500 ms. The hazard warning switch needs to be operated to deactivate the hazard warning lights. Immobiliser The PATS function is integrated in the BCM. Correspondingly, the send/receive unit is directly connected to the BCM (previously it was connected to the powertrain control module (PCM)). After reading in the key code (in ignition lock position "0", "I" or "II"), a corresponding message is placed by the BCM on the HS CAN databus for the PCM.
