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 - GGND terminals.

NOTE:
- When inspecting deceleration sensor, remove it with the bracket together. Do not remove the sensor from the bracket. When replacing deceleration sensor, replace the sensor with it assembled to the bracket assembly.
- Do not apply voltage of 6 V or more to terminals VGS and GGND.




c. Check the output voltage of GL1 and GL2 terminals.

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.

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