Chrysler P1389 Code is an error code that is associated with the Automatic Shutdown Relay Output Voltage to the Powertrain Control Module (PCM). This code is triggered when the engine is cranking, and the PCM does not detect any voltage on the ASD Relay Output circuit. This code can be caused by several issues, from a damaged ASD relay connector to a failed PCM. In this article, we will explore the causes and solutions to the Chrysler P1389 Code.
Causes and Solutions for Chrysler P1389 Code
| Cause | Solution |
|---|---|
| ASD Relay Connector is Damaged, Loose or Shorted | Replace the connector, or ensure that it is securely connected |
| ASD Relay Output Circuit is Open Between Relay and PCM | Check the wiring for any damage and replace if needed |
| ASD Relay Power Circuit is Open | Test the power from Fused B+ and replace the circuit if necessary |
| ASD Relay is Damaged or Failed | Replace the relay if it is damaged or not working correctly |
| PCM has Failed | Replace the PCM with a new one |
Chrysler P1389 Code is an error code that can be difficult to diagnose. It is important to know the causes and solutions of the code in order to properly and efficiently troubleshoot and fix the issue. By understanding this code and its associated causes and solutions, you can save yourself time and money when it comes to diagnosing and repairing your vehicle. With the right knowledge, you can identify the issue quickly and get your vehicle back on the road.
Damaged ASD Relay Connector
One of the primary causes of the Chrysler P1389 Code is a damaged, loose, or shorted ASD Relay Connector. This can happen if the connector is damaged due to wear and tear, or if it is not securely connected to the relay. To fix this issue, you will need to replace the connector, or ensure that it is securely connected.
Open ASD Relay Output Circuit
Another cause of the code is an open ASD Relay Output Circuit between the relay and the PCM. This can happen if the wiring is damaged or if it is not properly connected. To fix this issue, you will need to check the wiring for any damage and replace it if necessary.
Open ASD Relay Power Circuit
The open ASD Relay Power Circuit is another cause of the code. This can happen if the power from Fused B+ is not working correctly. To fix this issue, you will need to test the power from Fused B+ and replace the circuit if necessary.
Damaged or Failed ASD Relay
If the ASD Relay is damaged or failing, then it can cause the Chrysler P1389 Code. This can happen if the relay is worn out from age or if it has been damaged. To fix this issue, you will need to replace the relay if it is damaged or not working correctly.
Failed PCM
The last cause of the code is a failed PCM. This can happen if the PCM has been damaged or if it is not working correctly. To fix this issue, you will need to replace the PCM with a new one.
Conclusion
The Chrysler P1389 Code is an error code that can be caused by several issues, from a damaged ASD relay connector to a failed PCM. By understanding the causes and solutions of the code, you can save yourself time and money when it comes to diagnosing and repairing your vehicle. With the right knowledge, you can identify the issue quickly and get your vehicle back on the road. So, if you encounter a Chrysler P1389 Code, then make sure to use the causes and solutions outlined in this article to save time and money.
