MBS-2 Installation

Trailer Warning Lamp

Normal Operation

Like the ABS Malfunction Lamp, the Trailer Warning Lamp will come ON for

two seconds then go OFF at each stationary power up. This indicates that the

Trailer Warning bulb and wiring harness are operational.

NOTE: On units manufactured June, 2002 or later, either an LED or an

incandescent bulb can be used for the Trailer Warning Lamp.

If the lamp does not illuminate at power up, refer to ABS Malfunction and

Trailer Warning Lamp Troubleshooting on page 43.

Continuous Brake Apply Warning

The continuous brake apply warning is a feature of the MBS-2 that signals the

operator if the treadle valve on the tractor has become stuck open, resulting in

the brakes being applied without the operator’s knowledge. The warning is

initiated based on vehicle speed and the duration the stop circuit is powered.

The graph below illustrates when the warning becomes active. The line

represents when the warning is triggered. See Figure 27.

Wheel End Temperature Warning

The wheel end temperature warning is initiated when the wheel speed sensor

detects a rise in temperature on one of the wheel ends.

Refer to Figure 28 for a description of trailer warning lamp flash codes and

their causes.
