Hi,

i have two unknown pwm outputs i can't idenify.

In the PWM routine, i have:

-EGR solenoid
-Wastegate solenoid
-Purge solenoid
- front heater
- rear heater

and:
two outputs i labeled "front heater bank2" and "rear heater bank2". But i don't remember why i did this, and whats this for.
They are both disabled by faa bit2.

Thx Jan

 

V6 setup
Each bank of cylinders might have its own O2 sensors

 

They are enabled at some roms and disabled at other roms.

Do they have some function on our ecu's?
