2023 GMC Yukon XL Active Suspension Mode Switch Replacement Cost

The mode selector switch is not an extremely commonly replaced component of the active suspension system. Since most drivers will find the mode they prefer and never change the selection to another handling mode the switch will experience very little wear. In most cases, along with other buttons on the center console, spilled drinks are the biggest hazard to this switch.

If the mode switch fails or fails to actuate the suspension, it will be the first component tested. This is doubly true if the switch is an independent switch with no other function. Diagnosing the switch is as simple as checking for power, and checking for continuity in different settings for older vehicles, but newer vehicles will be slightly more difficult. Since newer vehicles will be controlled by an active suspension control module, signal voltage in each setting will be checked at the switch to determine if the switch is sending the correct voltage to the control module. Also, reference voltage from the control module must be present, and possibly battery voltage as well. Integrated switches, those which control several other settings, will likely not be suspected since they are most often a simple controller. In lieu of an integrated switch, the control module for the active suspension system will be suspected.

Interior switches are simple to replace, and only require removal of the switch from the panel in which it is embedded, and possibly removing a panel to gain access to the mounting fasteners. An electrical connection will be removed and connected to the new switch before reinstallation. Of course, testing must be conducted before final installation.

We recommend thorough and proper testing of any component before replacement. This will limit frustration, wasted time and financial cost. In some cases simply swapping the switch may turn out to be a good repair, but there are many other components to an active suspension system, so the odds are against this being the case.

Typical scanners will allow the user to view emissions codes, anti-lock brake system codes, and check readiness of emissions systems, however, active suspension system trouble codes are not likely to be visible with code readers. Professional scan tools can be used to access and clear codes, and make diagnosis a much more simple process, however, diagnosis can be done with a multi-meter and service manual.

A bad active suspension system mode selection switch can be replaced by anyone. However, diagnosing an active suspension system will prove out of reach of most DIY mechanics. These systems are atypical, and most people will have never serviced these systems. In the event of active suspension system electronic issues, it may be best left to a professional.
