My 2013 Lexus LX570 is displaying a PCS light issue. After checking the diagnostic trouble codes (DTCs), I found two errors: U0122 — 'Lost communication with Vehicle Dynamics Control Module' and U1101 — 'Lost communication with Distance Control ECU'. Currently, I do not have access to proper diagnostic tools or procedures to fully investigate or resolve these issues. Seeking advice on how to accurately diagnose and fix these specific DTCs in a 2013 Lexus LX570.
