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 boost control solenoid, by supplying ground to device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "A" output 5 (boost control solenoid driver circuit) detects an improper voltage level, DTC is set.
Conditions for setting DTC:
- Ignition is on.
- An improper voltage level has been detected on boost control solenoid driver circuit.
- Conditions present for at least 30 seconds.
