If all qualifying parameters detailed above are met, please refer to Warranty Memo #1925 to verify eligibility and to determine the replacement SCR to use for the repair. If the unit is fitted with an eligible SCR, only the identified replacement SCR must be used in completing this field action. The verification and selection tool takes precedence over any other prior published service/part guidelines, for the duration of this field action. Note : For eligible ISL CM2350 L101 the SCR catalyst must be replaced. Refer to procedure SCR Catalyst Remove and Install in section 011-036 of Service Manual 4310787 (ISL9 CM2350 L101). New SCRs delete the NH3 Sensor and move from a three (3) sensor to a NEW two (2) sensor configuration. This action provides coverage for a wiring harness connector plug to cap and secure the NH3 sensor connector that will no longer be used. The installation of a wiring harness connector plug in the NH3 sensor connector will require an ECM calibration update. Please refer to Attachment C for a table of ECM base codes and CPLs for your consideration. Please refer to Attachment D for detailed instructions on the installation of the wiring harness plug. 2. Download the latest calibration available on QuickServe® Online. Recalibrate the ECM as described in Procedure 019-032 of Service Manuals 4310787 (ISL9 CM2350 L101). 3.
