98 San Marino SH

when want to reset the ECU...which one do I pull....i would logically think the ECU fuse. What does the radio/clock fuse have anything to do with the ECU??

There is no fuse labeled ECU. The ECU is run off of the radio/clock fuse.

but there is a fuse labeled ECM though.

Ah interesting. The Helm's manual says to remove the radio/clock fuse. I wonder what the ECM fuse does.....gotta look it up in the electrical manual.

The ECU fuse is on the driver side kick panel, on my 4th gen at least. Look on the labels on the cover. I just disconnect my negative to make sure it's 100% reseted.

The clock/radio fuse disconnects the constant-power to the memory section of the ECU, whereas the other fuse is switched-power (ie.: when ignition if on), and does NOT affect the memory.

i asked this question a long while back, but i was ridiculed by someone.
