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.
All parts of poison-hemlock (leaves, stem, fruit, and root) are poisonous. Leaves are especially poisonous in the spring, up to the time the plant flowers. Fresh leaves are unpalatable, so livestock seldom eat hemlock when other feed is available.
