Control Module

The first step to replace the electronic Suspension Control Module (ESC module) requires removal of the rear seat back followed by moving the rear seat back insulator out of the way. Start the replacement process by gently depressing the locking tabs of the esc module electrical connectors to disconnect them. Next push the esc module toward the vehicle's center and take it out of the bracket. Assemble the esc module to the bracket first before pulling it away from the bracket center until complete engagement and finally reattaching the esc module electrical connections . Reinstall the rear seat back after placing back its insulator in position. Complete calibration for new ecm modules because esc modules keep dtc c0563 in memory resulting in non-auto-clear detection until calibration finishes. Connect the scan tool to the data link connector dlc before following display instructions from the tool while maintaining engine off and turning on the ignition. Verify the scan tool has the most up-to-date chassis application program installed.

The first step before changing the air Suspension Control Module includes following the air suspension depressurization procedure instead of removing air supply pipes which could result in personal injury or vehicle damage. The first step involves taking off the compressor assembly from the vehicle which you should then position it on a workbench. Detaching the electrical connector begins the process of releasing upper and lower tabs for control module extraction from its bracket. To install the module pair the control module to the bracket while fitting both upper and lower locking tabs in place followed by reconnecting the power connector before reinstalling the compressor into the vehicle. The suspension position calibration procedure should be executed to finalize the system setup.

Begin by removing the compressor assembly from the vehicle and placing it on a bench.
