If the rear suspension is not affected its probably a leak or a front height sensor.

The CHT sensor is in the back of the pass side the head 1" from the 02 sensor. Im very sure because i just found it myself. I think i can assess it through the wheel weld. Your Navi was be in limp mode until its replaced. Thats was it sounds bad and no power.
good luck

Screen is made of liquid crystals that have to be warm inorder to function. The older they get the more susepitble to cold they area and are slow to react. There is probably a fuction built in to alllow warning of the screen and prevent damage.. Read your manual

Your air bags are leaking and sounds like your air compressor doesn't work. Suspect new air bags and a new air compressor. And/Or ride height sensor located at the drivers side fender well above the controll arm.

Shift Interlock System
The shift interlock system prevents shifting from PARK unless the brake pedal is depressed. The shift interlock system consists of a shift lock actuator mounted at the base of the steering column or on the floor shifter mechanism. If the ignition switch is in the RUN position, the shift lock actuator is ON unless the brake pedal is depressed.

Symptom Chart
Symptom Chart Condition Possible Sources Action
  • The shift interlock system does not release/lock correctly

U2023 Fault Received from External Node Instrument Cluster REFER to Section 418-00 .
Do you have a no - crank - no start condition ? Do you know what medium speed C.A.N is ? Their is a high an medium speed C.A.N serial data communication network for all the modules on the vehicle to share info on. Does a scan tool communicate with the instrument cluster ? Or any or all modules on the vehicle ?
Instrument Cluster The instrument cluster uses the medium speed CAN. The instrument cluster also uses the high speed CAN to communicate with other modules. It is an analog face cluster with a digital odometer. The instrument cluster displays a variety of information. For additional information, refer to Section 413-01 .
Principles of Operation
The vehicle has 4 module communications networks:
  • the standard corporate protocol (SCP) communications network (Navigator with navigation system only)
  • the international standards organization (ISO) 9141 communications network
  • the medium speed controller area network (CAN)
  • the high speed CAN
The diagnostic tool connects to all 4 networks through the data link connector (DLC). This makes diagnosis and testing of these systems easier by allowing one diagnostic tester to be able to diagnose and control any module on the 4 networks from one connector. The DLC can be found under the instrument panel between the steering column and the audio unit.
  • The instrument cluster does not respond to the diagnostic tool
  • Circuit or connection in the medium speed controller area network (CAN)
  • Circuit or connection in the high speed CAN
  • Instrument cluster
  • Go To Pinpoint Test I .

confirm that the compressor does switch on and supplies air
then check supply pipes and connections for leaks
