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

INSPECTION

1. INSPECT ACCELERATION SENSOR ASSEMBLY



(a) Inspect the acceleration sensor LH.

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

(c) 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).

(d) 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 is tilted

Change between approx. 0.9 to 2.3 V

NOTICE:

Do not apply a voltage of more than 6 V.

HINT:

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


(e) Inspect the acceleration sensor RH.

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

(g) Connect the positive (+) end of the batteries to terminal 3 (SHB) of the acceleration sensor and the negative (-) end of the batteries to terminal 2 (SHG). Then measure the voltage between terminal 1 (SGFL) and terminal 2 (SHG).

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

Standard Voltage:

Tester Connection

Sensor Condition

Specified Condition

1 (SGFL) - 2 (SHG)

Sensor stationary

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 more than 6 V.

HINT:

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