After reading the article below in the Power Steering bible, I was curious as to where I could find more information on the PPS ECU. Pictures would be helpful, but I'm not seeing anything under my steering wheel.

Thanks in advance.

"Checking the power steering ECU. There is a PPS ECU specifically put there for the purpose of switching the solenoid on and off. Its located under the steering wheel right next to tilt & telescopic ECU. Check the voltage between the ECU - and ground connectors. - connector is in the upper left corner and ground is in lower left corner if you look at the connector while its plugged in into the ecu. voltage should be between 0.15 and 0.2 V with the engine idling. lift the car and put it in Drive. check the voltage while car running at 60 mph. it should be between 0.04 and 0.16 V. If its no you have to get yourself a new ECU. Don’t forget to check the wire from the ECU to the solenoid and make sure its ok might be just a wire problem"

 

near steering column under dash iirc.

 

It's a blue colored box, says ECU, POWER STEERING AISIN JAPAN on it.
