22. External Connection Test
Display information regarding externally exposed terminals or sensors such as illumination terminals,
vehicle speed pulse terminals, etc. Corresponding terminals are different depending on destination.
The status of item shown on the following figure is updated for every 0.5 second.
OK/NG Determination Condition
GYRO Test
OK/NG Determination of GYRO VOLTAGE
(Obtain the difference of gyro output value and offset standard value and perform OK/NG determination.)
Offset Standard Value : 1.35 [V]
Within 0.025 [V]
Within 0.025 ~ 0.05 [V] : Within the allowable aging tolerance (USABLE is displayed)
More than + 0.05 [V]
OK/NG Determination of DELTA SIGMA Value
(Perform variation determination from Gyro variance value)
Less than 30.0 : Variation OK (OK is displayed)
More than 30.0 : Variation NG (NG is displayed)
G SENSOR Test
OK/NG determination of G SENSOR VOLTAGE
(Obtain the difference of G Sensor output value and offset standard value and perform OK/NG determination.)
Offset Standard Value : 1.5 [V]
Within 0.2 [V]
Within 0.2 ~ 0.26 [V] : Within the allowable aging tolerance (USABLE is displayed)
More than 0.26 [V]
OK/NG Determination of DELTA SIGMA Value
(Perform variation determination from G Sensor variance value)
Less than 80.0 : Variation OK (OK is displayed)
More than 80.0 : Variation NG (NG is displayed)
* USABLE Range is the OK range of parts in which aging change is taken into consideration.
(USABLE is displayed on the screen)
* OK Range is the value determined when shipping test.
* At the Service Quarter, please determine OK products as parts if it is in the range of USABLE.
Temperature Sensor Output Value
