INSPECTION
PROCEDURE
1. INSPECT ACCELERATION SENSOR
(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:
for LH Side| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 1 (SGFL) - 2 (SGG) | Sensor stationary | Approx. 2.0 to 2.5 V |
| Sensor vibrating vertically | Changes between approx. 0.9 and 3.6 V |
| Tester Connection | Condition | Specified Condition |
|---|---|---|
| 1 (SGFR) - 2 (SGG) | Sensor stationary | Approx. 2.0 to 2.5 V |
| Sensor vibrating vertically | Changes between approx. 0.9 and 3.6 V |
| *A | for LH Side |
| *B | for RH Side |
| *a | Component without harness connected (Front Acceleration Sensor LH) |

NOTICE:
- Do not apply a voltage of more than 6 V.
- Do not drop the front acceleration sensor. If it is dropped, replace it with a new one.
- Never place the front acceleration sensor upside down.
HINT:
When the acceleration sensor is tilted, it may output a different value.
