Q: My Ford has U0100 and won’t communicate with the scan tool — is it the connector?
A: U0100 (lost communication with PCM) is frequently caused by a corroded PCM connector rather than a failed PCM. Inspect the 9-pin connector before replacing the PCM, as PCM replacement requires programming and is significantly more expensive.
Q: Are terminals included?
A: Yes, terminals are included with all variants.
