If you're experiencing a problem and someone mentioned a "PCM diode," they likely mean:
* A faulty component *within* the PCM: This requires replacing the entire PCM, not just a single diode.
* A diode in a related circuit: The problem might actually be in a separate component's circuitry that interacts with the PCM. This could be in various sensors, actuators, or wiring harnesses. More information about the specific issue is needed to pinpoint the location.
To diagnose the problem, you'll need to provide more context:
* What is the symptom? (e.g., engine won't start, check engine light is on, specific code)
* What led someone to suspect a "PCM diode"? (e.g., a mechanic's diagnosis)
With more information, a more accurate diagnosis and location of the faulty component can be determined. Consider taking your vehicle to a qualified mechanic for proper diagnosis and repair.
