Red channel wheel speed sensor S1A has an erratic output voltage.
Loose sensor, connection, bracket or exciter, damaged exciter, sensor is not properly adjusted or has worn cable insulation or worn sensor block clip, wheel bearing failure, wheel bearing is not properly adjusted (these faults will only occur at speeds greater than 6 mph). Measure the AC voltage at the sensor in question while rotating the wheel at a rate of about one rotation every two seconds. The output should be at least 200 millivolts (0.2V AC). If this is not the case, push in the sensor until it touches the exciter and rotate the wheel again. If this doesn’t correct the problem, then the sensor should be replaced. Verify the tire and wheel size is large enough for 100 tooth exciter ring. If these faults re-occur at the same speed, inspect the exciter ring for damage. Smaller wheels and tires require 80 tooth exciter rings. Reference Tire Scale Factor Chart. Verify sensor and valve wiring/plumbing is correct. See side-by-side and axle-by-axle confi gurations.

PLC Select 2M Plus (ABS Auxiliary Codes). Note: These Codes are only used with PLC Select 2M Plus ABS that supports trailer Auxiliaries. Auxiliary Channel has an open circuit or the ECU (Electronic Control Unit) has an auxiliary device connected and is not programmed to be. Note: These codes do not affect ABS performance and do not illuminate the tractor trailer ABS warning lamps.
