Firestone IntelliRide™ Systems Troubleshooting Guide
 
Problem  Light display status  Symptoms  Possible solutions
Compressor will not run Lights are toggling slowly Vehicle will not raise due to low reservoir pressure 1. Compressor fuse blown
2. Power wire disconnected
3. Compressor relay ground wire disconnected
4. Compressor not grounded
Compressor runs for no apparent reason   Compressor will be triggered whenever the ECU calls for inflation at any wheel If the staged response wire is not connected correctly, the IntelliRide system will try to re-level the vehicle too quickly, thereby triggering the compressor to run.
Vehicle will not re-level itself after being manually deflated or inflated   Customer has turned off the leveling system and manually raised or lowered vehicle Ride height sensors are out of range...manually adjusting the vehicle closer to its ride height will get the sensors back into range and allow the leveling ECU to regain control
Vehicle seems to "hunt" for the correct ride height   System is very active...inflates and deflates many times per minute Recalibrate the height sensors paying particular attention to the "calibration" height setting that creates the tolerance window of the correct ride height. An active system indicates that the tolerance window is too narrow...the system is trying to get "too close" to the selected ride height.
Vehicle takes too long to re-level   When weight is added or subtracted from the vehicle, it may take 40-45 seconds for the leveling system to respond. This may be normal. The "default" response time is approx. 40 seconds. When the vehicle is stationary, the response should be approx. 5 seconds. There is a trigger wire that is connected to the neutral safety switch that tells the ECU if the vehicle is in "park" or "drive"
