Replacing a faulty Powertrain Control Module (PCM) on a Ford vehicle requires transferring the original module’s configuration data. This data, often referred to as “As-Built” data, ensures the new PCM functions correctly with the specific vehicle. But what happens when the original PCM is damaged and can’t communicate? This article explores how to obtain the necessary information, focusing on the importance of the Ford Pcm Tear Tag Number.
When replacing a functioning PCM, Ford’s standard programming procedure involves “inhaling” the As-Built data from the old module using a diagnostic scan tool. This data is then transferred to the new PCM. However, this process is impossible with a non-communicative PCM.
In such cases, Ford recommends Programmable Module Installation (PMI). This procedure involves obtaining the As-Built data through a paid subscription on the Ford Motorcraft website. Using the vehicle’s VIN, you can purchase the As-Built data, which consists of hexadecimal codes that need to be manually entered into the programming software. This can be a time-consuming process.
Alternatively, a quicker method exists for retrieving the necessary information – utilizing the Ford PCM tear tag number. This number, found on a sticker affixed to the PCM, contains critical information about the module’s configuration. While not a direct replacement for the full As-Built data, the tear tag number can be used in conjunction with diagnostic software to program a new PCM. This method streamlines the process and avoids the need for manual hexadecimal code entry.
Locating the tear tag number is crucial. The PCM is typically located in the engine compartment, often near the firewall. Once located, carefully examine the module for a sticker or tag. The tear tag number will be a series of alphanumeric characters. This number should be recorded and readily available during the programming process.
By utilizing the Ford PCM tear tag number, technicians can efficiently program replacement PCMs even when the original module is damaged. This approach saves time and simplifies the process compared to manual As-Built data entry. Remember to consult your diagnostic software’s instructions for specific guidance on using the tear tag number during programming. While the tear tag provides vital information, a full As-Built data retrieval might still be necessary for complete configuration in certain situations. Always refer to Ford’s official documentation for the most accurate and up-to-date procedures.
