Circuit Description

Output Driver Modules (ODM) are used by PCM to turn on current-driven devices needed to control various engine and transaxle functions. Each ODM can control up to 7 outputs, including EVAP vent solenoid driver circuit, by supplying ground to device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "D" output 5 (EVAP vent solenoid driver circuit) detects an improper voltage level, P1675 is set.
