Deceleration Sensor Operation Diagnosis System

DECELERATION SENSOR OPERATION DIAGNOSIS SYSTEM

CAUTION: While checking the deceleration sensor operating diagnosis system, ABS does not work and brake system works as a conventional brake system.





DECELERATION SENSOR CHECK

A. Connect 3 dry batteries of 1.5 V in series.
B. Connect VGS terminal to the batteries' positive (+) terminal, and GGND terminal to the batteries' negative (-) terminal, apply about 4.5 V between VGS and GGND terminals.

NOTE: Do not apply voltage of 6 V or more to terminals VGS and GGND.





c. Check the output voltage of GL1 terminal.

HINT: If the sensor is tilted too much it may show the wrong value.
If dropped, the sensor should be replaced with a new one.
The sensor removed from the vehicle should not be placed upside down.

D. When replacing the deceleration sensor
Perform the deceleration sensor zero point calibration. Component Tests and General Diagnostics
