MODULATOR REMOVAL
1. Locate the modulator that will be replaced and clean
the exterior.
2. Identify and mark or label all air hoses and their
respective connections on the valve to facilitate ease
of installation.
3. Disconnect both air lines and the electrical connector.
4. Remove the modulator from the vehicle.
5. Remove any air hose fittings present. These fittings
will be re-used in the replacement modulator.
MODULATOR INSTALLATION
1. Install all previously-removed air hose fittings, making
certain thread-sealing material does not enter the
valve.
2. Install the assembled valve on the vehicle.
3. Reconnect both air lines to the valve using the
identification marks made during step 5 of Modulator
Removal.
4. Reconnect the electrical harness to the modulator.
5. After installing the valve, test all air fittings for excessive
leakage and tighten as needed.
