Inspection

INSPECTION

PROCEDURE

1. INSPECT ACCELERATION SENSOR ASSEMBLY

(a) Connect 3 1.5 V dry cell batteries in series.

(b) Connect a positive (+) lead from the batteries to terminal 3 (SGB) and a negative (-) lead to terminal 2 (SGG).

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

Standard Voltage:

*A	for LH Side
*B	for RH Side
*a	Component without harness connected (Front Acceleration Sensor Assembly)
	Top
	Bottom

NOTICE:

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

HINT:

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

If the result is not as specified, replace the front acceleration sensor assembly.

Installation

INSTALLATION

PROCEDURE

1. INSTALL ACCELERATION SENSOR ASSEMBLY LH (for LH Side)

(a) Install the acceleration sensor assembly LH with the 2 nuts. Torque: 13 N·m {133 kgf·cm, 10 ft·lbf} NOTICE: Avoid any impact to the acceleration sensor assembly LH. Do not drop the acceleration sensor assembly LH. If it is dropped, replace it with a new one.

(b) Engage the clamp.

(c) Connect the connector to the acceleration sensor assembly LH.

2. INSTALL ACCELERATION SENSOR ASSEMBLY RH (for RH Side)

(a) Insert the guide to the body hole and install the acceleration sensor assembly RH with the bolt. Torque: 7.5 N·m {76 kgf·cm, 66 in·lbf} NOTICE: Avoid any impact to the acceleration sensor assembly RH. Do not drop the acceleration sensor assembly RH. If it is dropped, replace it with a new one.

(b) Connect the connector to the acceleration sensor assembly RH.
