Can anyone give me guidance on a Code E-30? The truck runs fine but the check engine light intermittently comes on and it shows the code E-30 when you turn the key on. I do not have a manual.

check your EGI, Main C and Ignition relays
check fuses F6 and F7
check your body grounds on the battery side of the frame.
