Test
1 - Check the integrity of the terminal
and the cable:
- ECM 1/G3 pin
- ECM 1/H3 pin
- ECM 1/H2 pin
2 - Check the value of the resistance:
- ECM pin 1/H4 at ECM pin 1/H3
(injector 2)
- ECM pin 1/H4 at ECm pin 1/H2
(injector 1)
- ECM pin 1/H4 at ECM pin 1/G3
(injector 3)
3 - Check whether the cable is short
circuited:
- ECM Pin 1/H3 at the chassis
- ECM Pin 1/H2 at the chassis
- ECM Pin 1/G3 at the chassis
4 - Check the continuity of the cable:
- ECM Pin 1/H4 at the injection relay
- ECM Pin 1/H3 at connector pin 2
(injector 2)
- ECM Pin 1/H2 at connector pin 2
(injector 1)
- ECM Pin 1/G3 at connector pin 2
(injector 3)
