Checking components and wiring
Check the cable that relates to the diagnostic trouble code (DTC). Check for a short-circuit to supply voltage.
Check between:
- Engine control module (ECM) terminal #A16 (#A16) and injector terminal #2 (ECM-200C, injector 1)
- Engine control module (ECM) terminal #A34 (#A34) and injector terminal #2 (ECM-201C, injector 2)
- Engine control module (ECM) terminal #A15 (#A15) and injector terminal #2 (ECM-202C, injector 3)
- Engine control module (ECM) terminal #A33 (#A33) and injector terminal #2 (ECM-203C, injector 4)
- Engine control module (ECM) terminal #A14 (#A14) and injector terminal #2 (ECM-204C, injector 5).
Remedy as necessary.
