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)
