Deceleration Sensor Check (4WD)

NOTE: If sensor is tilted too much during testing, it may give false voltage readings. Do not place sensor upside down when removed from vehicle.

Connect 3 "D" cell batteries in series, creating 4.5 volts. Connect VGS terminal of deceleration sensor to positive (+) side of batteries. See Fig 1. Connect GGND terminal to negative (-) side of batteries.
Measure voltage between terminal GL1 and ground at deceleration sensor. Ensure sensor is within specifications. See DECELERATION SENSOR SPECIFICATIONS . If sensor is not within specification, replace sensor.
