Fuse box: Power up relay, ECM relay

Recommended Posts

I talked to a "really good" mechanic recommended on the phone


He said to check my "power-up relay" and my "ECM relay" in my fuse box


I cant find anything called a power up or ECM relay on my '99 CTD


Are these two relay something that dont even exist ?

We do not have a power up relay. We use an ASD relay. That may be what he was talking about.

ASD relay was what was bad on my truck causing it not to charge. I thought it was the PCM because the PCM controls charging /w an internal voltage regulator.
