Pinpoint Tests RK: REDUCTANT Injector: Introduction

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 injector
reductant pump
harness circuits: RDINJPWR and RDINJGND
reductant dosage control module (5H298)
PCM (12A650)
