Inspection [04/2018 -]: Procedure

WARNING: This page is about a different car, the 2022 Toyota Avalon, 2021 Toyota Avalon, 2020 Toyota Avalon, and 2019 Toyota Avalon. However, it is still accessible from the selected car via links, so may be relevant.

INSPECT ACCELERATION SENSOR ASSEMBLY

Connect 3 1.5 V dry cell batteries 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
1 (SGFL) - 2 (SGG)	Sensor stationary	Approx. 2.0 to 2.5 V
1 (SGFL) - 2 (SGG)	Sensor vibrating vertically	Changes between approx. 0.9 and 3.6 V

FOR RH SIDE

Tester Connection	Condition	Specified Condition
1 (SGFR) - 2 (SGG)	Sensor stationary	Approx. 2.0 to 2.5 V
1 (SGFR) - 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 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.
