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) Wiring Color Terminal Description Condition Specified Condition
a9-7 (IGB) - a9-10 (GND) B - W-B Power source Ignition switch ON 11 to 14 V*1
10.5 to 16 V*2
Ignition switch off Below 1 V
a9-3 (LKSW) - a9-10 (GND) V - W-B Steering pad switch signal
(LDA main switch signal) 		Ignition switch off
LDA main switch off 		1 MΩ or higher
Ignition switch off
LDA main switch on 		228 to 252 Ω
a9-10 (GND) - Body ground W-B - Body ground Ground Always Below 1 Ω

*1: w/o Stop and Start System

*2: w/ Stop and Start System


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.
