Re: Diagnostic Screen on Nav-equipped hybrids
schmidtj — The TCH's Overall Electrical Wiring Diagram (attached below) shows quite clearly that the four wheel speed sensors are connected only to the Skid Control ECU. The NAV unit receives the SPD signal from the Combination Meter. The Combination Meter is connected to various ECUs and to the CAN bus. The NAV unit is also connected to the CAN bus but not to the wheel speed sensors. I reiterate what I said in my post above.
