What happens if you interfere with the ASD relay?
Interference with the supply of power to the injectors or ignition coil by the ASD relay can give rise to ignition coil problems and other problems of the various engine components. The check engine light will be illuminated.
Where does the Powertrain Control Module grounds the ASD relay?
The Powertrain control module grounds the ASD relay from the side of the coil through terminal 85. Voltage is being supplied to the coil side of the ASD relay by terminal 86
How does the ASD relay work on a fuel pump?
The ASD relay shuts down the fuel ignition and the fuel pressure immediately after the ignition key is turned off; this is done to prevent problems like fire, dieseling, etc. How is it possible to jump a fuel pump relay?
Where does terminal 30 connect to the ASD relay?
The rest of the circuit is not being supplied with power. When the fuel pump and automatic shutdown relay are powered by the powertrain control module (PCM), terminal number 30 connects to terminal 87 in an on position. Voltage is being supplied to the remaining part of the circuit by terminal number 87.
Where does the ground go on the ASD relay?
Once the key passes the anti-theft test, the PCM provides ground to the control coil side of the ASD relay on the brown white wire. Once the ASD relay receives ground from the PCM, the contacts close and the relay sends power back to the TIPM on the brown/white wire.
How does the automatic shutdown ( ASD ) relay work?
Consequently, The (PCM) operates the automatic shutdown (ASD) relay, by switching its ground circuit ON and OFF. The (ASD) relay will be shut-down; meaning the 12-volt power supply to the (ASD) relay will be deactivated by the (PCM); if the ignition key is left in the ON position.
Is it safe to bypass the ASD relay?
Bypassing the ASD relay in your vehicle is a safe move. Personally, I do not think that it will damage the vehicle only if it is done properly. It is because the power will still run through the stock wires that it was originally made to pass through.
What does the Check Engine light on an ASD relay mean?
Another symptom of a possible problem with the (ASD) relay is an illuminated Check Engine Light. So, If the computer detects that a problem with the (ASD) relay or circuit has occurred; it will illuminate the Check Engine Light to alert the driver of a problem. The Check Engine Light can also be activated for a wide variety of other reasons.
