Pinpoint Tests 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 quality module
- reductant level sensor
- harness circuits: CAN2+, CAN2-, GND, RDL1, RDL2, RDL3, SIGRTN and VPWR
- reductant dosage control module (5H298)
- PCM (12A650)
