Title: CRUISE CONTROL: FORWARD RECOGNITION CAMERA SYSTEM: TERMINALS OF ECU; 2018 MY Camry [03/2017 - 08/2018] |
TERMINALS OF ECU
NOTICE:
-
DTCs may be stored when connectors are disconnected during inspection. Therefore, be sure to clear the DTCs using the Techstream once the inspection has been completed.
-
Do not apply excessive force to the V6 forward recognition camera connector.
