Below are two pictures of what an ECU might look like, depending on the vehicle. There are a number of different types of ECUs, including an Engine Control Module (ECM), Powertrain Control Module (PCM), Brake Control Module (BCM), General Electric Module (GEM) and others.
Each leaf on a poison ivy plant has three smaller leaflets. Contact with any part of the poison ivy plant can cause red, swollen skin, blisters and severe itching, sometimes within hours after exposure. A poison ivy rash usually resolves on its own within a few weeks. In the meantime, soothe irritated skin with an over-the-counter topical treatment, such as calamine lotion. Oatmeal baths and cool compresses also might be helpful. Consult your doctor if you have a severe poison ivy rash or if the rash involves your face or genital area.
No, the poison ivy blisters are the caused by the body's natural allergic reaction to the plants. If the blisters break and ooze, the fluid does not contain the oil that causes spreading. The rash-causing oil, called urushiol, from the original contact with poison oak and poison ivy will continue spreading (unless removed) for the first one or two days. It is found in in all parts of poison ivy, oak and sumac plants whether dead, dormant or thriving.
