Maintenance Information
There is no regularly scheduled maintenance required for the
Meritor WABCO ABS or ABS/ATC. However, ABS does not change
current vehicle maintenance requirements.
앫
Lamp Check: To ensure the ABS tractor lamp is operating, drivers
should check the lamp every time the vehicle is started. When the
vehicle is started, the ABS lamp should come on momentarily. If it
does not come on, it could mean a burned-out bulb.

ABS Wheel Speed Sensors: Check the wheel speed sensor
adjustment and lubricate the sensor and sensor clip whenever
wheel-end maintenance is performed. Use only Meritor
WABCO-recommended lubricant, as specified in Section 4.
