Code 23 - Open Circuit In SAFING Sensor Feed Circuit: Description

Battery voltage is present at terminal No. 15 of diagnostic monitor at all times. Voltage at terminal No. 15 can be as high as 19 volts when ignition is on and back-up power supply in diagnostic monitor is charged up. Circuit No. 611 (White/Orange wire) is connected to circuit No. 612 (Purple/Orange wire) inside safing sensor. Voltage at terminal No. 23 should be the same as voltage at terminal No. 15 at all times. Diagnostic monitor compares voltage available at terminals No. 15 and 23. If voltage at terminal No. 23 is low, Code 23 will set.
