There is provided an in-vehicle electronic control apparatus suitable for enhancing a robust characteristic of a failure diagnosis process performed for a functional part having a function relating to a drive-control of an actuator.. A functional part (120) relating to the drive-control of an electric motor (12) includes a main functional part (120a) and an alternative functional part (120b) that is an alternative of the main functional part. When it is determined that the main functional part (120a) is normal based on diagnosis results of a main function diagnosis part (121) that diagnoses a failure of the main functional part (120a) and an alternative function diagnosis part (122) that diagnoses a failure of the alternative functional part (120b), an output selecting part (123) outputs an output value of the main functional part (120a) to a control unit at a subsequent stage, and when it is determined that the main functional part (120a) has a failure and the alternative functional part (120b) is normal, the output selecting part. (123) outputs an output value of the alternative functional part (120b) to the control unit at the subsequent stage, instead of the output value of the main functional part (120a), thereby making an operation guaranteed range of each diagnosis part wider than an operation guaranteed range of each functional part.
