Pcm power relay
The Power Relay is used to supply voltage to the PCM, in other words, it’s function is to deliver to the powertrain control module the adequate battery voltage needed for its operation. This contact type relay uses the traditional 5-wire design. The control circuit is activated by the ignition switch (pin 86) and the ground (pin 85).A power-train control module, abbreviated PCM, is an automotive component, a control unit, used on motor vehicles. It is generally a combined controller consisting of the engine control unit (ECU) and the transmission control unit (TCU). On some cars, such as many Chryslers, there are multiple computers: the PCM, the TCU, and the Body Control ...
