    Tech Tips


    • The power steering ECU (rack and pinion power steering gear assembly) uses waterproof connectors. Therefore, voltage or waveforms cannot be checked with the connectors connected to the vehicle.

    • Use the Data List and Active Test on the GTS to check the operation of the rack and pinion power steering gear assembly and check that communication is established.
