What is ASD relay location?
The 5-pin, 12-volt, Automatic Shutdown (ASD) relay is located in the Power Distribution Center (PDC). Refer to label on PDC cover for relay location. The ASD relay supplies battery voltage (12+ volts) to the fuel injectors and ignition coil(s).
What are the numbers on relay?
Numbers of a Relay Note that each pin is numbered. 85 and 86 are the coil pins while 30, 87, and 87a are the switch pins. 87 and 87a are the two contacts to which 30 will connect. If the coil is not activated, 30 will always be connected to 87a.
When does a 5 pin relay switch off?
A normally closed relay will switch power OFF for a circuit when the coil is activated. 5 Pin Relay 5 pin relays provide 2 pins (85 & 86) to control the coil and 3 pins (30, 87 & 87A) which switch power between two circuits. They have both normally open and normally closed connection pins.
How to determine the number of pins in a relay?
Try to touch the probes of multimeter on remaining pins to determine which are the pins actually connected with each other.These pins actually consist of normally closed (NC) pin/pins and common pin/pins. Based on this finding, the remaining pins must be normally open (NO) pins. **In this case, there is only 1 pair of pins found connected.
How do you find the ignition relay on a car?
When you locate the fuse box, open it and find the mapping on top of its lid. The key will tell you the exact position of the ignition relay as well as other relays and fuses. Once you have located the relay, gently pull on it to remove it from the fuse box. The relay looks like a rectangular block and is hard to miss.
How does a solid state relay switch work?
Solid-state relays (SSR) have no contacts and switching is totally electronic. Functions performed by heavy-duty equipment often need switching capabilities of electromechanical relays. SSR switch current using non-moving electronic devices such as silicon controlled rectifiers. SSR do not have to energize a coil or open contacts.
