No, one is electrical wether it be a relay or a contact or just a switch. And the transmission is totally mechanical.
No DDR2 and DDR are not compatible and so you can not add DDR2 RAM module in a DDR Slot. Electrical specifications like voltage, signal pinout and even mechanical size and shape of modules are different.
Go for MM (Material Management) module.
From Technical (Electrical) Point of View IO Module means Input and Out Put Module used in PLC Programming.
The Gem Module is a relay that control the majority of the electrical functions in late model ford vehicles
testing the starter
controls all of the electrical systems not related to the motor
The ignition module on a 2002 Impala is located in part of the electrical system. In some cars, the module kept the car from starting. When the key was turned there would not be a clicking noise. The module works with the passlock system of the car.
Remove the 3 coils which are help on by 2 5.5 mm bolts each. The module is now free. Remove electrical connector from ignition module. - Tech JK -----------------------------------
The electronic control module is an embedded system that controls one or more of the electrical systems in a motor vehicle. These are sometimes referred to as the car's computer.
It is very hard to diagnose electrical this way. However, it is most likely a bad battery or a bad ECM module.
These cars don't use a crank sensor - the ignition module watches the electrical properties of the #4 cylinder spark plug and uses that to calculate where the engine is within the mechanical rotation. If you are having troubles, verify/replace that spark plug and the wiring. In a past experience with this car, it turned out to be the ignition module, located under the coil packs.
