Auto A/C Control Module I/O Signal
HVAC SYSTEM (AUTO A/C) (DIAGNOSTICS)
*1: Unable to measure the voltage for digital signal.
*2: Voltage immediately after switching FACE
⇔
DEF or maximum COOL
⇔
maximum HOT (when the damper door is operat-
ing.) for mode door and air mix door
*3: Voltage immediately after the operation for the seat heater (Always measure the voltage immediately after turning the seat
heater to ON because once reached to the target value, it switches to ON/OFF action.)
