GM3RD (General Information)

GM3RD
The GM3RD has been Redesigned to accommodate new functions in the X5 FL. While some pin assignments have changed, operation and diagnostics remain the same. New features of the GM3RD include:
^ Revised software and hardware
^ Adaptation of HW for Interior Lighting (IB) changes
^ Additional Load Deactivation (VA2) to support peripheral control units
^ Integration of Soft Close Actuator (SCA)

The primary reason for the redesign of the GM3 was to integrate a new microprocessor. Additionally, other hardware changes were also implemented requiring a new printed circuit board.
^ Semiconductor control of lock activations (not relay)
^ Integrated Optical Entry Assist (OEM)
^ SCA
^ Elimination of heat sink
^ Pulse width modulated (PWM) signal for the interior lighting (IB), and reading lights supply line (VA)
