Control Module

You should start the Electronic Suspension Control Module (F55) replacement by disconnecting the rear storage compartment trim and the two bay board fasteners. Set the bay board at a distance from the body surface and position it with the module side facing up in the rear compartment. You should depress the locking tab to remove the ESC module from the bay board. Then disconnect the harness connectors from the ESC module. The installation requires plugging harness connectors into the ESC module then placing the ESC module into bay board tabs followed by locking tab installation until bay board placement at the vehicle body where Fastener Notice must be noted in Service Precautions. The bay board installation requires you to fasten the retaining nuts before tightening them to 9 Nm (80 inch lbs.). Afterward, install the rear storage compartment trim. Complete the procedure by programming the ESC module followed by scanning a tool to execute the Bump Stop Trim Set process.
