TROUBLESHOOTING (cont.)
The diagnostic lights on the WR8-760-2230 aftermarket IntelliRide system toggle fast as though it is attempting to change
heights, and the valve block clicks trying to pass air. However no height change occurs and there is no air pressure within the
reservoir tank.
(1) There is a potential blockage in the air dryer.
(2) The compressor connections are not sufficient.
(3) The pressure sensor is not connected.
The WR8-760-2230 system is locked down, with no functions. Both of the lights on the LED switch flash slowly.
There are a few different causes and solutions:
(1) The pressure sensor is unplugged. Insure that the pressure sensor is torqued into the valve block at the recommended torque
value of 7.2 ft-lbs (9.8 N-m). Make sure pressure sensor is plugged in firmly.
(2) The height sensor(s) is/are unplugged. Insure that each height sensors is securely connected into the wire harness.
(3) The height sensor(s) is/are out of range.
Insure that the height sensor arm travels within the recommended yellow area of the height sensor template. It is also important that the height
sensor are mounted correctly with the wire connection pointing up. (4) The pressure sensor is out of range. Insure the pressure sensor connector
is fully inserted and wires into the connector are not exposed (5) +5Volts removed. Ensure sensor power wire is inserted on the ECU connector.
The WR8-760-2230 is locked down, no function. The system will not level or change height. The lights toggle slowly.
The ground is removed from the valve block. Check grounding on valve block wire.
The WR8-760-2230 system is locked down, no function without any indication from control switch.
There are few potential causes and related solutions. (1) System is off due to the main ground removed. Check all fuses, power, ignition and
ground connections (2) The system is off due to the voltage battery is removed. Check all fuses, power, ignition and ground connections. (3) The
ignition connection is removed. Check all fuses, power, ignition and ground connections. (4) The service switch is showing red. Turn the service
switch so that it is showing all black. (5) Make sure the ignition wire is connected to a source of less than 1/2 amps.
The WR8-760-2230 system will not function. The leveling and ability to change height is disabled. Both lights flash slowly.
The pressure sensor low limit failure caused by grounding out. Insure the pressure sensor connector is fully inserted and wires into the connector
are not exposed.
The vehicle will attempt to raise the vehicle, but after an extended period of time the attempt is unsuccessful and the vehicle
returns to its previous height.
The 2230 IntelliRide system is designed to time-out if a height is not achievable. Common reasons for an unachievable height change include:
1) the air springs are too large and have air volume requirements that exceed the capabilities for this specific air system or, 2) the air springs do
not have enough load capacity to lift the vehicle.
