Checking Components And Wiring

Check between terminals #1 and #2 in the injector that relates to the diagnostic trouble code (DTC). Check the resistance.

Check the cable that relates to the diagnostic trouble code (DTC). Check for a short-circuit to ground.

Check between:

• Engine control module (ECM) terminal #A1 (#A1) and injector terminal #2 (ECM-200D)
• Engine control module (ECM) terminal #A25 (#A25) and injector terminal #2 (ECM-201D)
• Engine control module (ECM) terminal #A3 (#A3) and injector terminal #2 (ECM-202D)
• Engine control module (ECM) terminal #A2 (#A2) and injector terminal #2 (ECM-203D)
• Engine control module (ECM) terminal #A26 (#A26) and injector terminal #2 (ECM-204D).

Remedy as necessary.
