what does the ads relay control in a dodge durango
Have you ever wondered why your car shuts off or won't start with even the smallest issue? It's likely because of the ASD relay. This device is found in nearly every modern vehicle and serves as an automatik shut off device. But what exactly does it do, and how does it work?
What is the ASD relay, and what does it do?
- ASD stands for Automatik Shut Off Device and is an internal relay (sometimes external) found in most modern vehicles.
- The ASD relay serves as a bridge between different components in your car's engine operating system, allowing them to communicate and work together.
- For example, the transmission control module, engine control module, security immobilizer, RF receiver, and body control module all need to communicate with each other through the ASD relay.
- If any one of these components fails to communicate with the ASD relay, it won't release power to the engine, and the car won't start.
Different types of ASD relays:
- Auto shutoff for accessories
- Auto shutoff for security
- Auto shutoff for engine operation (the type discussed in this article)
Common misconceptions about the ASD relay:
- The ASD relay is not a security system like your key fob.
- The ASD relay does not control whether or not your car starts based on a bad key fob or RF receiver.
- The ASD relay only controls handshaking between different modules in your car's engine operating system.
The ASD relay is a crucial component in modern vehicle engine operating systems. Without it, your car wouldn't be able to communicate between different components, and you wouldn't be able to start your car. Knowing how it works and what it does can save you time and money in diagnosing and fixing issues with your car.

In this article, we will be discussing the ASD relay and its role in powering key electronics in a vehicle. We will also touch on the different types of theft and immobilizer devices and how they communicate with the computer.
- The ASD relay powers specific key electronics in the vehicle to allow it to operate under certain conditions.
- The fuel pump and computer are powered in the run position, not the on position.
- The ASD relay can be powered on in three ways: without a chip in the key, with an anti-theft module, or with an immobilizer.
- The anti-theft module is an interrupter that prevents the signal from being sent to the computer if it doesn't get what it wants, whereas an immobilizer communicates with multiple different things in order to operate.
- The ASD relay only turns on specific things in the computer and is usually powered by the computer.
- If the ASD relay is not operating, either the immobilizer is not sending the signal to the computer to tell the ASD relay to turn on, or the computer is not being told to come on.
- Without a scan tool, diagnosing these issues can be difficult, but a wiring diagram can help to see where the module gets its power from and what other things are powered by that computer.
- If the computer is not working, test to see if the immobilizer or anti-theft device is telling the computer that it can run, as the computer generates its own power and ground.
In summary, the ASD relay plays a crucial role in powering key electronics in a vehicle, and different types of theft and immobilizer devices communicate with the computer in different ways. Diagnosing issues can be challenging, but a wiring diagram can be a helpful tool in identifying the problem.
How To Check ASD Relay for Power Jeep TJ
In this video, we will be discussing the ASD relay, also known as the shutdown relay. This relay is responsible for disabling your vehicle if something major is going to happen to prevent further damage. The ASD controls various components such as O2 sensors, coil, and injectors. We will be bypassing the ASD in the LS swap in my Jeep to utilize those circuits for something else. In case you are having issues and suspect the ASD may be at fault, we will go through troubleshooting it together.
- Check the ASD fuse, as blowing it indicates a short circuit.
- Look at the O2 sensor wires and coil for any signs of grounding out and causing the fuse to blow.
- Ensure that constant power and ignition-on power are present and the computer-controlled ground is functioning.
- Check the PCM for any signs of failure.
Using a power probe and multimeter, we can simulate the ASD relay working and provide power to the circuits. If you suspect that the ASD relay is failing, swap it out with another relay to confirm.
In conclusion, the ASD relay is a crucial component in ensuring the safety of your vehicle. Troubleshooting it is a straightforward process, and you can do it yourself with the right tools. By bypassing the ASD in the LS swap, we can utilize those circuits for something else. I hope this video has been helpful, and if you have any questions or comments, please feel free to subscribe and follow along with my LS swap journey.

Fixing the ASD Relay on a 1998 Dodge Ram Pickup Truck
In this article, we will be discussing how to fix the ASD relay on a 1998 Dodge Ram pickup truck. We will go through the steps taken to diagnose the issue and the solution to get the truck running again.
The truck was not running and would only crank when attempting to start it. All other electrical components, such as lights and wipers, were functioning properly. The ASD relay, which is the automatic shutdown system for Chrysler, was not receiving power. Testing revealed that one of the pins on the relay was not receiving any voltage, which was causing the issue.
After checking the wiring for any breaks or faults, it was discovered that the issue was a blown 10 amp fuse in cavity 9 for the ASD relay. Replacing the fuse resolved the issue, and the truck was able to start and run properly.
1. Checked the wiring for any breaks or faults
2. Discovered a blown 10 amp fuse in cavity 9 for the ASD relay
3. Replaced the fuse
4. Truck was able to start and run properly
Fixing the ASD relay on a 1998 Dodge Ram pickup truck is a relatively simple process that can be done by anyone with basic knowledge of automotive electrical systems. By following the steps outlined above, the issue can be resolved quickly and efficiently, allowing the truck to run properly once again.

2005 Durango P0688 Diagnosis
In this article, we follow a technician as they diagnose a 2005 Dodge Dakota that is experiencing a crank start stall issue. The technician notes that there are 16 codes present, with the active code being P0688, which relates to the ASD main sense circuit. They suspect that there may be an open or corroded circuit between the fuse block and the engine control module, which is preventing the ASD relay from receiving power.
To confirm this, the technician probes into the ASD sense circuit and finds that there is only 75 volts present instead of the expected ignition positive. They decide to jumper power from an injector to the circuit and confirm that the relay now receives a high signal when the key is cycled. The technician concludes that there is indeed an open circuit somewhere and advises the viewer to locate and repair it.
Overall, this diagnosis was considered an easy one, but the technician stresses the importance of taking the time to logically think through the issue and analyze the symptoms, even when the solution may seem obvious.
