Fig. Fig. 1: G-sensor attach to fender apron

The G-sensor may be removed by unbolting it from the fender apron. Disconnect the wire harness and remove the unit. The G-sensor may be tested with an ohmmeter.

Resting flat on a level surface, the sensor should have approximately 610 ohms resistance. Acceptable variance is approximately 60 ohms. When tilted in the direction of travel, the resistance should become at least 100 kilo-ohms when the unit is held at an angle of 14-21 degrees. The G-sensor only operates in the direction of travel; no effect will be seen from tilting in any other direction.

When reinstalling the sensor, make absolutely certain it is placed in the correct position. If installed backwards, it will not allow the system to work.

Connect the wiring harness and secure the retaining bolts.
