Applicable truck models
This document applies exclusively to the Caterpillar C15 on-highway truck engine in the MXS configuration (serial numbers MXS00001-UP). The DTC 0071-01 is generated when the idle shutdown timer expires with coolant temperature above 38 °C (100 °F) and vehicle speed at zero. The guide also references related circuits including the check engine lamp circuit, service brake pedal position switch circuit, clutch pedal position switch circuit, vehicle speed and speedometer circuit, and PTO switch circuit. The idle shutdown timer is a customer-specified parameter programmable from 1 to 1440 minutes. If diagnostic code 84-08 (vehicle speed signal out of range) is active, the timer will not operate.
