Deceleration Sensor Diagnostics
NOTE:
During deceleration sensor diagnosis, ABS functions like a standard brake system.
- Connect 3 "D" cell batteries in series, creating 4.5 volts. Connect VGS terminal of deceleration sensor to positive (+) side of batteries. See Figure. Connect GGND terminal to negative (-) side of batteries.
- Measure voltage between GL1 and ground, and GL2 and ground terminals of deceleration sensor. Ensure sensor is within specifications. See DECELERATION SENSOR SPECIFICATIONS . If sensor is not within specification, replace sensor. A deceleration sensor malfunction will cause ABS light to flash Code 79.
