Page 9: Overview
Overview Overview The air manifold distribution module (AMDM) consists of a mounting base that can hold up to five electrically operated air solenoid valves that can be used to operate air system accessories. The mounting base provides a common air supply and a common electrical connector to operate the valves. -
Page 10: Maintenance
Maintenance Maintenance AMDMs require no regularly scheduled maintenance. However, they must be kept clean and free of debris or ice build-up. -
Page 11: Mounting Specifications
AMDM must be mounted in a location that is not directly exposed to road splash, debris or direct spray from power washers. AMDM WITH FOUR SOLENOID VALVES SOLENOID MOUNTING VALVE SOLENOID BASE MOUNTING VALVE SCREWS EIGHT-PIN ELECTRICAL CONNECTOR PNEUMATIC DELIVERY PORTS EXHAUST PORTS PNEUMATIC SUPPLY PORT 4016941a For technical assistance, contact the WABCO Customer Care Center at (855) 228-3203. -
Page 12: Air Lines
Air Lines Air Lines CAUTION Identify the air lines before disassembly. If air lines are removed, they must be reinstalled in the same location to avoid accidental activation of devices or activation of the wrong device. CAUTION Never apply voltage to the assembly except by means of the proper connector in the vehicle wire harness. -
Page 13: Air Supply
Air Supply Air Supply CAUTION Air supply must be confirmed prior to attempting any repair or replacement of an AMDM. The air supply is provided through a pressure protection valve. Air will not be available to the AMDM if the supply pressure is less than the pressure protection valve setting. -
Page 14: Troubleshooting And Testing
Troubleshooting and Testing Troubleshooting and Testing CAUTION When troubleshooting and testing the AMDM, do not damage the connector pins. CAUTION The mounting base contains diodes that are polarity sensitive and can be damaged if power is incorrectly applied. To avoid damaging the diodes, apply power using the vehicle manufacturer’s wire harness connector. -
Page 15: Resistance Test
Troubleshooting and Testing Resistance Test If the voltage is within the acceptable range of 9.5 to 15 volts but the valve still does not operate, test the solenoid. Use a volt-ohm meter to check the resistance of both the valve and the module base as follows: Remove the electrical connector from the module base. -
Page 16: Valve Check
Troubleshooting and Testing If no leakage is found on the front and sides of the valve, loosen the two mounting screws that attach the assembly to the vehicle and inspect for leaks from the back side of the assembly. 4016944a Replace the leaking solenoid valve (refer to Replacement Procedures). -
Page 17: Replacement Procedures
Replacement Procedures Replacement Procedures Solenoid Valve Follow the removal procedure above to remove the valve from the module. Position the air supply and electrical connector O-rings in the proper location on the base of the module. ELECTRICAL PINS O-RING 4016945a Install the new solenoid valve by engaging the electrical pins first. - Page 18 CVS unites ZF’s former Commercial Vehicle Technology and Commercial Vehicle Control Systems divisions, the latter being formed following ZF’s acquisition of WABCO in Spring 2020.
