1. Bad gauge caused unit not to communicate with diagnostic computer
2. Replaced gauge, able to communicate, married to ECU.
3. Faults P0562 low voltage.
a) Battery fully charged and load tested
b) Rectifier outputting at 13.5v, replaced in case it was inducing issues into the system
c) Fuses are good for the two 30amp
d) Relay is good, swapped with a new one just in case
Issues
1) Diagnostic computer on "monitor" shows ZERO volts. So while there is adequate voltage, the system is not seeing it.
2) Unit wont idle, replaced TPS with a new one. Reset TPS, it defaults to the fault setting. On "monitor" it is not getting a reading. Unit does rev out okay and getting full rpms.
3) Plug in the lanyard and "low fuel" "low voltage" shows up. 3/4 of a tank of fuel with correct ohm reading. Low fuel alarm is intermittant some times it come in some times not. Low voltage is constant.
4) Service manual does not show where the voltage is monitored at.
Any suggestions of where to look next? I am leaning towards the ECU.
Thanks
