Inspection [12/2017 - ]: Procedure

INSPECT FRONT ACCELERATION SENSOR

Connect 3 dry cell batteries (1.5 V) in series.
Connect a positive (+) lead from the batteries to terminal 3 (SGB) and a negative (-) lead to terminal 2 (SGG).

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

Standard Voltage

FOR LH SIDE:

Tester Connection	Condition	Specified Condition
L47-1 (SGFL) - L47-2 (SGG)	Sensor stationary	Approx. 2.0 to 2.5 V
L47-1 (SGFL) - L47-2 (SGG)	Sensor vibrating vertically	Changes between approx. 0.9 and 3.6 V

FOR RH SIDE:

Tester Connection	Condition	Specified Condition
L36-1 (SGFR) - L36-2 (SGG)	Sensor stationary	Approx. 2.0 to 2.5 V
L36-1 (SGFR) - L36-2 (SGG)	Sensor vibrating vertically	Changes between approx. 0.9 and 3.6 V

NOTE:

Do not apply a voltage of more than 6 V.
Do not drop the front acceleration sensor. If it is dropped, replace it with a new one.
Never place the front acceleration sensor upside down.

HINT:

When the acceleration sensor is tilted, it may output a different value.
