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 Malfunction Indicator Light (MIL) in Instrument Panel (I/P), by supplying ground to device PCM is commanding on. ODMs can diagnose each circuit individually. If ODM "A" output 1 (MIL driver circuit) detects an improper voltage level, P1641 is set.
Conditions required to set DTC are
- Ignition is on.
- An improper voltage level has been detected on MIL driver circuit.
- Listed condition is present longer than 30 seconds.
