# Service bulletin T2084

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

This Temporary Repair Practice authorizes certified repair locations to upfit certain ISB and ISL CM2350 engines with an improved SCR Catalyst. MY2013 thru MY2014 engines that qualify, a new wiring harness and calibration update is required. The engine must show open for this field action, experience a complaint or symptom in which troubleshooting results in the replacement of the SCR, and the SCR part number must match the Affected Part Number list.
