Five Steps to Avoid
Unnecessary Regens
Often, a technician will see the word " DPF, " " Aftertreatment, " or " SCR " in a fault description and instinctively
attempt a forced DPF regeneration (regen) to correct the issue. Unfortunately, this has costly consequences
when a forced regen is the incorrect procedure, such as:
* Wasted Fuel - A forced regen can burn up to 1.5 gallons of fuel.
* Component Stress - The heat required for a forced regen can weaken vehicle components over time.
* Unnecessary Downtime - The regen can last 30-60 minutes, plus additional time afterward for the
components to cool down.
These issues affect the profitability of a fleet and the service center performing the service. Fortunately,
we have five tips to help reduce the occurrence of unnecessary regens in the shop.
1.
Read the entire fault
description
3.
Don't quit reading when you see the
word " DPF. " Diagnostic tools that
offer enhanced fault descriptions
may provide more guidance on the
issue later in the text.
2.
Review the checklist
JPRO's aftertreatment diagnostics
feature provides an essential
aftertreatment diagnostics
checklist for the technician to
review. Following this set of diagnostic
procedures helps identify the root
cause and determine the correct
repair procedure.
Verify the regen zone
Technicians should make it a
habit to always check which regen
zone a vehicle is in, as it can immediately
indicate if a forced regeneration
is necessary. A regen is not
required if the truck is in zone 0 or 1.
4.
Troubleshoot the problem
An aftertreatment diagnostic
checklist can help identify many visual
issues, but at times more in-depth
troubleshooting is required to determine
the root cause. Use an assisted
troubleshooting tool like JPRO's Fault
Guidance feature that ensures you
follow all valid troubleshooting steps
before considering the regen.
5.
Follow detailed repair
procedures
Once you have identified the problem,
utilize the OE service manuals
or an online service like NextStep
Repair to follow instructions for
repairing the issue. These documents
ensure the job is done safely
and accurately and help technicians
avoid unnecessary procedures.
