Automotive Electronic Modules Types


[Music] in automotive electronics electronic control unit ECU is any embedded system that controls one or more of the electrical system or subsystems in the vehicle the electronic control unit ECU is a general term for any of a number of computer modules that receive input from sensors in the vehicle and control different electrical functions you they are the computer brains of the vehicle as autos become more complex and outfitted with more sensors and functions there can be dozens of different electronic control units at work in a single vehicle the ECU often consists of an 8-bit microprocessor random access memory RAM read-only memory ROM and an input output interface ECU’s may be upgraded by the manufacturer or by a third party they are usually protected to prevent unwanted tampering electronic control modules types for jeep grand cherokee WJ as example body control module BCM body control module VCM is attached to the junction block under the driver’s side of the instrument panel the BCM utilizes integrated circuitry and information carried on the programmable communications interface pci data bus network along with many hard-wired inputs to monitor many sensor and switch inputs throughout the vehicle the BCM supports many-body electrical features such as interior lighting exterior lighting intermittent wipers remote radio accessory delay and heated seats passenger door module PDM passenger door module PDM is located behind the right door trim panel integrated within the door switch assembly the door modules control various electronic features such as power door locks power windows power mirrors courtesy lighting and the lift gate lock motor airbag control module ACM air bag control module ACM is located underneath center console housing behind the shifter assembly the microprocessor in the airbag control module contains the supplemental restraint system logic circuits and controls all of a supplemental restraint system components electronic vehicle Information Center AVIC electronic vehicle Information Center AVIC module is located within overhead console the electronic vehicle Information Center is an interactive display system it gives the driver some information such as compass temperature and trip sunroof module SM sunroof module is located in the overhead console as part of the sunroof assembly Sun roof module controls operation of the sunroof open close and vent functions you Rane sense module RSM Rain sense module is located inside of the windshield between the rearview mirror mounting button and the windshield header concealed behind a molded plastic trim cover that snaps over the module housing the microprocessor-based rain sensor module senses moisture in the white pattern on the outside of the windshield glass and since wipe commenced to the body control module BCM instrument cluster I see instrument cluster is located left dashboard instrument cluster provides gauge and indicator control instrument cluster utilizes the PCI bus to obtain most but not all of the information needed to control the gauges and indicators driver door module DDM driver door module DDM is located behind the left door trim panel integrated within the door switch assembly the door modules control various electronic features such as power door locks power windows power mirrors courtesy lighting and the lift gate lock motor heated seat module HSM heated seat module location is under the drivers seat mounted on a bracket that is located between the power seat track and a seat cushion frame heated seat module HSM performs heated seat functions memory heated seat module M HSM memory heated seat module location is under the driver’s seat mounted on a bracket that is located between the power seat rack and the seat cushion frame memory heated seat module M HSM performs memory seat functions and heated seat functions you adjustable pedals module APM adjustable pedals module location is under – above brake pedal adjustable pedals module APM controls operation of the adjustable pedals you century key immobilizer module skim century key immobilizer module location is under the steering column opening cover attached to the bottom side of the steering column housing the century key immobilizer module contains a radio frequency RF transceiver and a microprocessor the skim transmits RF signals to and receives RF signals from the century key transponder through a tuned antenna ring integral to the skim housing you transmission control module TCM transmission control module TCM is located on the right side of the engine compartment near the firewall mounted to the inner fender or on the left side of instrument panel the transmission control module controls all electronic operations of the transmission the TCM receives information regarding vehicle operation from both direct and indirect inputs and selects the operational mode of the transmission controller anti-lock brakes cab controller anti-lock brakes cab is attached to the hydraulic control unit hcu under the hood in front of the master cylinder controller anti-lock brakes cab controls the ABS also controls electronic brake distribution EBD you powertrain control module PCM powertrain control module PCM is located on the cowl panel right rear side of the engine compartment the PCM is a pre-programmed triple microprocessor digital computer it regulates ignition timing air fuel ratio emission control devices charging system certain transmission features speed control air conditioning compressor clutch engagement and idle speed [Applause] [Music]
