OBD 1 Hondata S300 A12 FANC triggering randomly.
Hi All,
I'm having some problems with my A12 FANC output.
I have SPAL 13" radiator fan that I wired as follow:
Fan ground--> chassis ground
Fan 12v positive--> wired through a relay by using the A12 output to trigger the relay to supply the fan with 12v.
Everything was working fine for a while but I tried to load a map I made on my laptop using S manager version 1.4.4 through a different laptop with S Manager version 1.4.3 installed on it and all of a sudden the A12 output started triggering randomly when I put my ignition switch ON.
Is it possible that the FANC driver got messed up?
I've tried to put my ignition switch on ON with the Hondata S300 module removed from the ECU and A12 did not send out any trigger signals.
Do you guys have an idea of what could be going on?
