Fault meaning and symptoms
The document defines fault code 2963 as Engine Coolant Temperature – Data Valid But Above Normal Operational Range – Least Severe Level. The coolant temperature sensor is a variable resistor sensor and is used to measure the temperature of the coolant of the engine. The electronic control module (ECM) supplies 5 VDC to the coolant temperature signal circuit. The condition is monitored on SPN 110, FMI 0/15, and is annunciated with no dashboard warning lamp. Each fault is worked with the INSITE electronic service tool, cross-referencing associated procedures 019-019, 019-032.
Applicable truck models
This procedure covers Cummins ISX11.9 CM2250/ISB6.7 CM2250/ISC8.3 and ISL9 CM2250/ISX15 CM2250 engines built for the 2010-12 on-highway emissions platform, so it suits Class 8 trucks and vocational chassis running these engines. Confirm the exact application and current calibration against the official Cummins website before ordering parts.
Who needs this Cummins fault code 2963 manual
Diesel technicians and workshop owners who read 2963 on the INSITE service tool use this manual to follow the factory-approved diagnostic tree instead of replacing parts by guesswork. It is equally useful for fleet maintenance staff verifying a repair before returning a truck to service.
