CHECK FORWARD RECOGNITION CAMERA
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.

|---|---|---|---|---|
| a9-7 (IGB) - a9-10 (GND) | B - W-B | Power source | Ignition switch ON | 11 to 14 V |
| Ignition switch off | Below 1 V | |||
| a9-1 (HTR) - a9-10 (GND) | G - W-B | Forward recognition with heater hood sub-assembly operation signal | Ignition switch ON
Forward recognition with heater hood sub-assembly not operating |
11 to 14 V |
| Ignition switch ON
Forward recognition with heater hood sub-assembly operating |
Below 1 V | |||
| a9-10 (GND) - Body ground | W-B - Body ground | Ground | Always | Below 1 Ω |
Measure the waveform according to the value(s) in the table below.
| Terminal No. (Symbol) | Wiring Color | Terminal Description | Condition | Specified Condition |
|---|---|---|---|---|
| a9-2 (STRV) - a9-10 (GND) | Y - W-B | LIN communication signal | Ignition switch ON | Pulse generation |
Check for pulses according to the value(s) in the table below.
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.
