Firestone 4-corner, Installation Instructions Manual

TROUBLESHOOTING

The height change works, but the WR8-760-2230 system will not level. The left-rear corner is exhausted fully. The LED height
display shows the current height.

The right-front valve is switched with the left-rear valve. Correct the air line connection with the corresponding air spring location and the solenoid
valve connection.

The height change works, but the WR8-760-2230 system will not level. The right-rear corner is exhausted fully. The LED light dis-
play shows the current height.

The left-front valve is switched with the right-rear valve. Correct air line connection with air spring location and solenoid valve block.

On the WR8-760-2230 IntelliRide system the height change works but leveling is confused. The system is very active and unable
to achieve level. The LED switch displays the current height.

The left-front valve is switched with right-rear valve, or left-rear valve is switched with right-rear valve. Another possibility is the left-front height
sensor is switched with the right-front height sensor, or left-rear height sensor is switched with right-rear height sensor. Correct air line connection
with air spring location and solenoid valve block; or position height sensor locations according to the wire harness labels.

On the WR8-760-2230 IntelliRide system the height change and leveling is confused. System will detect if a height change is
made but can take up to 2 minutes. The LED lights toggle slow.

There are a couple possible causes and related solutions. (1) A possible cause is the left-front valve is switched with left-rear valve. Correct air line
connection with air spring location and solenoid valve block. (2) Another possible cause is the front height sensors are switched with the rear
height sensors. Correct the location of the height sensors to the corresponding corners as indicated on the wire harness.

On the WR8-760-2230 IntelliRide system the height change up will not work; will not level up. The current height is displayed on
the LED lights.

The possible cause is the inlet valve is removed. Check for pinched airlines and check wire connections to valve block.

On the WR8-760-2230 IntelliRide system the height change down will not work; will not level down. The current height is dis-
played on the LED lights.

The possible cause is the exhaust valve is removed. Check for pinched airlines and check wire connections to valve block.

On the WR8-760-2230 IntelliRide system the height change will not work properly; system will attempt to height change and will
go back to previous height. Will not be able to level corner. The LED lights show that the current height is displayed.

The possible cause is any corner valve is removed. Check for pinched air lines and check wire connections to valve block.

The WR8-760-2230 IntelliRide system cannot make a height change; the compressor will not run. The LED lights toggle slowly.

There are a few possible causes: (1) The possible cause is the compressor fuse is blown. (2) Compressor power not connected. (3) Ground on
relay connector not connected. (4) Compressor not grounded. Solution: Check the compressor ground, compressor fuse and relay connections.

The WR8-760-2230 IntelliRide system will not level or height change to the set height. The LED lights show the current height.

Calibration height set too far from the highest vehicle height. Redo calibration height so that it is approximately 1-inch below the highest vehicle
height.

The WR8-760-2230 IntelliRide system is very active at one height. The LED lights show that the current height is displayed.

A possible cause is that the park wire is not connected, meaning the system is looking to level the vehicle every 5 seconds instead of every 40 sec-
onds. Please install the park wire as described in the installation manual.
