Pinpoint Tests RG: REDUCTANT Pump: Introduction

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)
