2004 Nissan Armada Air Levelizer Suspension Repair

Troubleshooting the circuit, replacement of compressor, suspension control unit, height sensor, and reprogramming the air levelizer via CONSULT. Note, in an attempt to shorten this already long video I excluded the installation of the airshocks and will upload that as a separate video. Synopsis The 2004 Armada was purchased used in 2017 with 191K miles on it. The previous owner indicated they had the air suspension "disabled". Through this process I discovered only 7.5/8.5 Volts to the compressor when there should be 12Volts. The issue was 1) bad compressor, 2) bad height sensor, 3) the programming was set to adjust the height to maximum (thus effectively disabling the system). Reprogramming of the vehicle height was required and needed a tool (Nissan CONSULT-III). Replacement of the suspension control unit DOES NOT resolve the issue. reprogramming the ECU via CONSULT or another tool is required. Also note I originally swapped the relays behind the battery as my initial test for if the relay was bad (26:10), however I placed the method for testing the relay earlier in the video (23:00)
