Cummins ISM code 1695 diagnosis
Fault code 1695 reports that the sensor supply 5 voltage has risen above normal or shorted to a high source. Sensor supply 5 provides a 5-volt feed for the aftertreatment diesel particulate filter differential pressure sensor, the remote accelerator, the tachograph speed sensor, and accelerator position sensor 2, all through the ECM OEM harness connector. According to the Cummins Shop Talk guidance, technicians should first verify that the ECM calibration is correct and recalibrate if necessary before component replacement. Possible causes listed in the document include:
- A short circuit to a power supply.
- A damaged sensor.
- A damaged ECM power supply.
Applicable truck models and engines
This document applies to Cummins ISM CM871 (2007-09) engines and the closely related ISX CM871 platform used in on-highway trucks, so it suits heavy-duty tractors and vocational trucks fitted with these engines and their aftertreatment systems. Always confirm the engine dataplate and refer to the OEM troubleshooting and repair manual for chassis-specific pin numbers. Full specifications are published on the Cummins official website.
