CHECK FORWARD RECOGNITION CAMERA
- NOTICE:
- ·
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.

a.
Measure the voltage and resistance according to the value(s) in the table below.
| Terminal No. (Symbol) | Terminal Description | Condition | Specified Condition |
|---|---|---|---|
| T9-7 (IGB) - T9-10 (GND) | Power source | Ignition switch ON | 11 to 14 V |
| Ignition switch off | Below 1 V | ||
| T9-10 (GND) - Body ground | Ground | Always | Below 1 Ω |
b.
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.
| Terminal No. (Symbol) | Terminal Description | Condition | Specified Condition |
|---|---|---|---|
| T9-5 (CA1P) - T9-10 (GND) | CAN communication signal | Ignition switch ON | Pulse generation
(See waveform 1) |
| T9-11 (CA1N) - T9-10 (GND) | CAN communication signal | Ignition switch ON | Pulse generation
(See waveform 2) |
| T9-6 (CANH) - T9-10 (GND) | CAN communication signal | Ignition switch ON | Pulse generation
(See waveform 1) |
| T9-12 (CANL) - T9-10 (GND) | CAN communication signal | Ignition switch ON | Pulse generation
(See waveform 2) |
