Pinpoint Tests RJ: REDUCTANT Tank Level: Introduction

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2018 Ford Transit-350 HD, 2018 Ford Transit-350, 2018 Ford Transit-250, 2018 Ford Transit-150, and 2018 Ford F-550 Super Duty. 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 quality module
reductant level sensor
harness circuits: CAN2+, CAN2-, GND, RDL1, RDL2, RDL3, SIGRTN and VPWR
reductant dosage control module (5H298)
PCM (12A650)
