Tests 1 Through 5:

Tests 6 Through 9:

Symptom:
INTERMITTENT SIGNAL FROM REAR SENSOR

When Monitored and Set Condition:
INTERMITTENT SIGNAL FROM REAR SENSOR - EBC 2
When Monitored:
1. No output signal from sensor for 15 milliseconds (ms).
2. Average filtered wheel speed computation above 19 km/h (12 mph) with the brake released or above 32 km/h (20 mph) with the brake pedal applied.

OR

1. Rear wheel acceleration reversing sense in between two sampling periods.
2. Magnitude of rear wheel acceleration or deceleration exceeding 3g in the second sample period.

Set Condition:
Criteria 1 and 2 satisfied 128 times within a 21 second period.

INTERMITTENT SIGNAL FROM REAR SENSOR - EBC 325
When Monitored:
1. Ignition turned on for 3.5 seconds.
2. Average filtered speed computation for the two front wheels above 6 km/h (4 mph).
3. Speed computation for each suspect sensor above 32 km/h (20 mph) (brake applied or ABS active) or 19 km/h (12 mph) (brake released and ABS inactive).

Set Condition:
No output signal from sensor for 15 milliseconds (ms).
