Checking components and wiring

Check the pump control module connector. Check for contact resistance and oxidation.

Check the cable between Engine Control Module (ECM) terminal #B47 (#B57) and pump control module terminal #1. Check for an open circuit, short circuit to ground and supply voltage.

Remedy as necessary.

HINT: The diagnostic trouble code (DTC) may be caused by a defective pump control module.
