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.

CHECK FORWARD RECOGNITION CAMERA

(a) Measure the voltage and resistance according to the value(s) in the table below.
