The Ford U0100:87 Code is a diagnostic trouble code (DTC) that is associated with the car’s powertrain system. This code indicates that the powertrain control module (PCM) is not sending data messages to the body control module (BCM) over the high speed controller area network (HS-CAN1). When this occurs, the PCM is unable to communicate with the BCM, resulting in a loss of powertrain control. This code can be caused by a number of issues, ranging from missing messages due to component reset events to periodic transmission where the repetition time is too high. Solving this issue requires an understanding of the underlying cause of the code, as well as an understanding of the car’s powertrain system.
Causes and Solutions for Ford U0100:87 Code
| Cause | Solution |
|---|---|
| Incorrectly installed wiring | Check the wiring and make sure it is securely connected to the PCM and BCM. |
| Data messages not sent by PCM | Check the PCM for any errors and replace the PCM if necessary. |
| Bad connections between PCM and BCM | Check the connections between the PCM and BCM and replace any damaged wires. |
| Software incompatibility | Make sure that the software versions of the PCM and BCM are compatible and update them if necessary. |
The Ford U0100:87 Code is a common trouble code that can cause serious issues to the powertrain system of your car. When this code is triggered, it means that the powertrain control module (PCM) is not sending data messages to the body control module (BCM) over the high speed controller area network (HS-CAN1). This can be caused by a number of issues, such as incorrect wiring, bad connections between the PCM and BCM, or software incompatibility. To resolve the issue, it is important to identify the underlying cause and apply the appropriate solution. By understanding the potential causes and solutions for this code, car owners and mechanics can quickly and effectively resolve the issue and restore the car’s powertrain system.
Incorrectly Installed Wiring
One common cause for the Ford U0100:87 Code is incorrectly installed wiring. If the wiring between the PCM and BCM is not securely connected, it can cause a disruption in the flow of data messages. To check for this issue, it is recommended to inspect the wiring and make sure that it is properly connected and secured.
Data Messages Not Sent by PCM
Another potential cause of the Ford U0100:87 Code is if the PCM is not sending data messages to the BCM. This can be caused by errors in the PCM software, such as missing messages due to component reset events or periodic transmission with a repetition time that is too high. To check for this issue, it is recommended to inspect the PCM for any errors and replace it if necessary.
Bad Connections Between PCM and BCM
The Ford U0100:87 Code can also occur if there are bad connections between the PCM and BCM. If the connections are not properly secured, it can cause disruptions in the data messages sent from the PCM to the BCM. To check for this issue, it is recommended to inspect the connections between the PCM and BCM and replace any damaged wires.
Software Incompatibility
The Ford U0100:87 Code can also be triggered if there is software incompatibility between the PCM and BCM. If the software versions of the two components are not compatible, it can cause disruptions in the data messages sent between them. To check for this issue, it is recommended to make sure that the software versions of the PCM and BCM are compatible and update them if necessary.
Conclusion
The Ford U0100:87 Code is a diagnostic trouble code that is associated with the car’s powertrain system. It can be caused by a number of issues, such as incorrectly installed wiring, data messages not sent by the PCM, bad connections between the PCM and BCM, or software incompatibility. To resolve the issue, it is important to identify the underlying cause and apply the appropriate solution. By understanding the potential causes and solutions for this Ford U0100:87 Code, car owners and mechanics can quickly and effectively resolve the issue and restore the car’s powertrain system.
