Rear Acceleration Sensor Inspection

Connect 3 dry batteries of 1.5 V in series.

Connect the positive (+) end of the batteries to terminal 3 (SGV) of the acceleration sensor and the negative (-) end of the batteries to terminal 2 (SGND). Then measure the voltage between terminal 1 (SGRR) and terminal 2 (SGND).

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

Standard Voltage:

Tester Connection	Sensor Condition	Specified Condition
1 (SGRR) - 2 (SGND)	Sensor stationary	Approx. 2.0 to 2.5 V
	Sensor tilted	Changes between approx. 0.9 and 2.3 V

HINT:

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

NOTICE:

1. Do not apply higher than 6 V.
   
2. Do not drop the rear acceleration sensor. If it is dropped, replace it with a new one.
   
3. Never place the rear acceleration sensor upside down.
