INSPECTION

PROCEDURE

1. INSPECT FRONT CENTER ULTRASONIC SENSOR (for LH Side)

(a) Check the resistance.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
4 (BI) - 6 (EI)	Always	10 kΩ or higher
4 (BI) - 1 (BO)	Always	Below 1 Ω
5 (SI) - 2 (SO)	Always	Below 30 Ω
6 (EI) - 3 (EO)	Always	Below 1 Ω

If the result is not as specified, replace the front center ultrasonic sensor.

2. INSPECT FRONT CENTER ULTRASONIC SENSOR (for RH Side)

(a) Check the resistance.

(1) Measure the resistance according to the value(s) in the table below.

Standard Resistance:

Tester Connection	Condition	Specified Condition
4 (BI) - 6 (EI)	Always	10 kΩ or higher
4 (BI) - 1 (BO)	Always	Below 1 Ω
5 (SI) - 2 (SO)	Always	Below 30 Ω
6 (EI) - 3 (EO)	Always	Below 1 Ω

If the result is not as specified, replace the front center ultrasonic sensor.
