Title: SUSPENSION CONTROL: FRONT ACCELERATION SENSOR: INSPECTION (2008 LX570)

INSPECTION

1. INSPECT ACCELERATION SENSOR



NOTICE:

Do not drop the acceleration sensor. If it is dropped, replace it with a new one.

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

(b) Connect the positive (+) end of the batteries to terminal 3 (SGB) of the acceleration sensor and the negative (-) end of the batteries to terminal 2 (SGG). Then measure the voltage between terminal 1 (SGFR*1, SGFL*2) and terminal 2 (SGG).

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

Standard Voltage:

for RH

Tester Connection

Condition

Specified Condition

1 (SGFR) - 2 (SGG)

Sensor is not tilted

Approx. 2.0 to 2.5 V

Sensor is tilted

Change between approx. 0.9 to 2.3 V

for LH

Tester Connection

Condition

Specified Condition

1 (SGFL) - 2 (SGG)

Sensor is not tilted

Approx. 2.0 to 2.5 V

Sensor is tilted

Change between approx. 0.9 to 2.3 V

NOTICE:

Do not apply a voltage of higher than 6 V.

HINT:

The voltage may differ according to the amount that the sensor is tilted.

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