Pinpoint Tests RG: REDUCTANT Pump: Introduction
WARNING: This page is about a different car, the 2020 Ford F-550 Super Duty, 2020 Ford F-450 Super Duty, 2020 Ford F-350 Super Duty, 2020 Ford F-250 Super Duty, and 2020 Ford F-150. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Regeneration may occur during normal operation. During regeneration, diagnostic procedures may display biased values. If a regeneration occurs during diagnostic procedures, allow the process to complete before continuing diagnostics.
This pinpoint test is intended to diagnose the following:
- reductant pump
- reductant pump control module
- harness circuits: RDPAP, RDPBP, RDPC, RDPCP, RDPGND, RDPM and VPWR
- reductant dosage control module (5H298)
- PCM (12A650)
