Rear Sensor Open

NAME OF CODE:
Right Front Wheel Speed Sensor Open
Left Front Wheel Speed Sensor Open
Rear Wheel Speed Sensor Open

SET CONDITION:
The following criteria must be met for this code to be detached.
1. No output signal from any sensor for initial 1.0 second period.
2. Continuously excessive sensor resistance for subsequent 1.0 second period.

THEORY OF OPERATION:
The CAB continuously monitors the wheel speed sensor circuits. The CAB sends a small signal through the sensor circuits. If the CAB does not receive the proper signal back, a Sensor Open code is set.

POSSIBLE CAUSES:
- Open circuit in sensor or sensor wiring (including connectors)
- Wheel speed sensor (+) circuit shorted to battery boltage
- CAB's internal wheel speed sensor IC shorted
