Abstract:
1. Method for power take-off control integrity diagnosis in a vehicle including a throttle controlled engine and a plurality of power take-off control switches, comprising: receiving power take-off engine control requests by a first processor in a dual processor controller adapted to establish throttle position in response to said requests; providing power take-off control switch data to a second processor in said dual processor controller; inferring validity and invalidity of said power take-off engine control requests from said power take-off control switch data with said second processor; and allowing establishment of throttle position in response to said power take-off engine control requests that are inferred valid with said second processor and disallowing establishment of throttle position in response to said power take-off engine control requests that are inferred invalid with said second processor.
