ECU1 fuse, the correct amps rating ,correcto?10A
not reading the service manual schematics is the loss.
the electrics on cars are complex 1 fuse may run 20 things no nobody can guess what, lacking the book.
the fuse blows for and short on the feed to stop FIRE.
ECU1 runs , let me count them all,
upto 12 things''
5 pins on ECU sure.
upto 3 Radiator and A/C condenser fans shorted.
purge control valve shorted. EVAP device.
2x Oxygen 02 sensors shorted, or as all LOVE to do SHORT the heater pins OUT. pin 4. or wires melted at them and touching exhaust pipe there, (loves)
last is DIAGNOSTIC MODULE FOR TANK LEAKAGE
PULL CONN # EM02. TO PROVE IT.
A TECH LOOKS AT both 02 FIRST THEY LOVE TO SHORT. AND DISCONNECTS THEM,
THEN DISCONNECT ALL listed devices 1BY1 TO FIND THE OFFENDING SHORT.
NEVER REPLACE THE MOST EXPENSIVE PArt first.
