Pinpoint Test RJ: Reductant Tank Level: 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 level sensor
harness circuits: RDL1, RDL2, RDL3, and RDLRTN
PCM (12A650)
