ATTESA ECU Fault Codes

[Dewayne2121]

My 4WD light had been coming on intermittently as of late and this past week it's been every drive after a few minutes. I checked the ATTESA ECU in the trunk of the car and it's giving me code 9 & 21. I know those are the ABS actuator relay or circuit and Throttle sensor or circuit. Anybody know of any quick ways I can resolve these issues. Having trouble finding solutions to these specific codes online.

The service manual goes into this pretty good. Has helped me diagnose similar codes.

And being in Japan where this car was build 25 years ago (that's a long time to know the car) you're in the best place for shop selection.

I forgot to update my location. I am now in the states. Never had any issues with the ATTESA while in Japan Currently in New Mexico
