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-2C0C, injector 1)
• Engine control module (ECM) terminal #A15 (#A15) and injector terminal #2 (ECM-2C1C, injector 2)
• Engine control module (ECM) terminal #A33 (#A33) and injector terminal #2 (ECM-2C2C, injector 3)
• Engine control module (ECM) terminal #A32 (#A32) and injector terminal #2 (ECM-2C3C, injector 4)
• Engine control module (ECM) terminal #A34 (#A34) and injector terminal #2 (ECM-2C4C, injector 5)
• Engine control module (ECM) terminal #A52 (#A52) and injector terminal #2 (ECM-2C5C, injector 6).

Remedy as necessary.
