NOTICE:: ·

Turning the ignition switch to ON with connectors disconnected may cause DTCs to be stored. Make sure to clear the DTCs after inspection has been performed.

·

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
T9-3 (LKSW) - T9-10 (GND)	Steering pad switch assembly signal (distance control signal)	Ignition switch ON, steering pad switch assembly (vehicle-to-vehicle distance control switch) on	Below 1 V
T9-3 (LKSW) - T9-10 (GND)		Ignition switch ON, steering pad switch assembly (vehicle-to-vehicle distance control switch) off	4.75 to 5.25 V
T9-7 (IGB) - T9-10 (GND)	Power source	Ignition switch ON	11 to 14 V
T9-7 (IGB) - T9-10 (GND)	Power source	Ignition switch off	Below 1 V
T9-10 (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.
