2 - Check the resistance value:
- ECM pin 1/E1 at ECM pin 1/F1
- ECM pin 1/E2 at ECM pin 1/F2
3 - Check whether the cable is short
circuited.
- ECM Pin 1/E1 at the chassis
- ECM Pin 1/E2 at the chassis
- ECM Pin 1/F1 at the chassis
- ECM Pin 1/F2 at the chassis
4 - Check the continuity of the cable:
- ECM Pin 1/E1at pin A of the stepper
connector
- ECMPin 1/E at pin B of the stepper
connector
- ECM Pin 1/F2 at pin C of the stepper
connector
- ECM Pin 1/F1 at pin D of the stepper
connector
5 - Check the continuity of the cable for
short circuiting:
- ECM Pin 1/E at ECM pin 1/F1
- ECM Pin 1/E2 at ECM pin 1/F2
6 - Check the resistance of the stepper
engine
- Between pin A / pin D
- Between pin B / pin C
7 - Re-connect the cabling, cancel the
fault code and activate the
functional test of the diagnostic
equipment (see Axone manual) to
view the checking operations of the
stepper engine
