Title: SUSPENSION CONTROL: FRONT ACCELERATION SENSOR: INSPECTION; 2019 - 2022 MY Avalon Avalon HV [04/2018 -        ]

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:

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.
