Circuit Description

This DTC will run when Electronic Throttle Control (ETC) learn procedure is not active and duty cycle range switch is greater than 80 percent. DTC will set when ECM determines that it has an internal open or short to ground. ECM turns on MIL and records the operating conditions in the Freeze Frame data on the second consecutive drive trip that the diagnostic runs and fails. DTC will clear when ECM turns off MIL after 3 consecutive drive trips that the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles in which there is no failure reported by this diagnostic or any other emission related diagnostic. DTC will also clear when battery is disconnected or cleared by scan tool.
