Nothing new on this thread. Read all of the helpful posts and still can find issues. Need to get close and quite to hear sensors and I confirmed all 4 clicking. No audible tone in the cab. Checked the connections to the module above the parking brake with no obvious kinks / damage. Look like new. Light on console appears to be working. What else can be checked? Bad module or speaker? Looks like the speaker can be unplugged and replaced.

Try unplugging the speaker and setting off the sensors and measure the output with a multimeter. If you have voltage (or needle movement) then most likely a bad speaker, otherwise the problem is elsewhere.
