Electrical analysis of the ECM power supply at the Front Zone
Module:
Fuse: FE21, 20 A, Pin 5, ECU: Must have around 12.5 Volt with
ignition Key turned on.
Fuse: FE30, 10 A, Pin 23, ECU: Around 12.5 Volt with Key-On, 0 Volt
with Key-Off.
Fuse: FE22, 10 A, Pin 50, ECU: Around 12.5 Volt (fixed
supply).
If there is no power supply recognized (neither to the FZM nor
to the ECU) please disassembly and reassemble central plug
from FZM. If the engine does not start problem still exist
please disassemble and reassemble both central plugs from ECU.
Now the engine should start. Concerning assembly of electrical
plugs, etc. please refer to TIS.
