Terminals Of Ecu [12/2019 - ]
- CHECK FORWARD RECOGNITION CAMERA NOTE:
- DTCs may be output when connectors are disconnected during inspection. Therefore, be sure to clear the DTCs using the GTS once the inspection has been completed.
- Do not apply excessive force to the forward recognition camera connector.
- Measure the voltage and resistance according to the value(s) in the table below.
Terminal No. (Symbol) Terminal Description Condition Specified Condition R5-7 (IGB) - R5-10 (GND) Power source Ignition switch ON 11 to 14 V Ignition switch off Below 1 V R5-10 (GND) - Body ground Ground Always Below 1 Ω - Check for pulses according to the value(s) in the table below.
HINT:
If the waveform is not similar to that shown in the illustration, a malfunction of a CAN bus line, terminating resistor, or the forward recognition camera is suspected.
