Applicable truck models
This procedure applies to Caterpillar C15 on-highway truck engines with serial number prefix MXS (configuration MXS00001-UP). It also references NKS and RKS prefix C15 engines. The document covers all six intake valve actuator solenoid circuits, addressing DTCs 285-05 through 290-06 for cylinders 1 through 6, covering both current-low and current-high fault conditions. The ECM detects a high current (short circuit) during five consecutive energize attempts and responds by logging the code, illuminating the check engine lamp, and defaulting to a reduced torque map.
