Duty cycle code retrieve is pre obd1- flash code ..not for HFM-SFI..

Don't have to wait for CE lamp indication to retrieve stored codes from other modules..
CE only comes up when faults effect emmissions paremeters..
So, go to both 8 and 14 and see what is in there..
Pin 1 is gnd [ neg], pin 16 is positive [ 12v] and the odd colored
wire goes to appropriate pin [in this case , both 8 and 14]
