Frank,
Hello. I am one of those owners that has the dreaded 2009 Dynasty with the CCM I just started reading about. I would like your expert opinion. I am having this same issue of losing any response of my smart wheel. I took voltage readings everywhere inside the smart wheel, see below. The readings were at the very minimum or just below the acceptable voltage. Because I was at 5.16V at the inlet connection of the clock spring and at 4.03V on the outlet side, I made a very uneducated guess that the clock spring was bad. So, I purchased and installed a new clock spring and it did not fix the problem. It makes no sense that I am getting >5V at the clock spring inlet connection and I lose >1V after the clock spring.
Here were my voltage readings:
Steering Wheel - Violet (recommended 0-5VDC) 4.5(my reading in wheel) (and at the connector to the clock spring under the dash 1.77); Blue (recommended 0-5VDC) 5.07(my reading in wheel) (and at the connector under the dash 4.3); Red (required 5VDC) 4.03(my reading in wheel) (and at the connector under the dash 5.16)
SW2 Wiper Variable (Blue 3.708) 3.22(my reading) (Violet 1.377) 1.10(my reading)
SW3 Wiper Wash (Blue 2.942) 2.41 (Violet 1.377) 1.10
SW4 Wiper Hi/Lo (Blue 3.708) 3.22 (Violet 0.961) 0.74
SW5 Wiper Off (Blue 2.286) 1.88 (Violet 1.377) 1.12
SW6 Marker Lamp Flash (Blue 2.942) 2.4 (Violet 0.961) 0.78
SW7 Cruise Resume (Blue 3.747) 3.39 (Violet 4.308) 3.44
SW8 Cruise Set (Blue 3.005) 2.49 (Violet 3.79) 2.91
SW9 Cruise Cancel (Blue 2.352) 1.88 (Violet 3.334) 2.64
SW10 Cruise On/Off (Blue 3.708) 3.11 (Violet 2.25) 1.85
SW11 Headlamp Flash (Blue 2.942) 2.44 (Violet 2.25) 1.81
Why do you think I am seeing the drop of more than 1V after the clock spring? Do you think I have a ground issue or do you think I should purchase and install the 5V converter that you recommend? When I click on the link that someone posted to purchase the 5V converter, it is 10AMP rated. What size of fuse do you recommend for this application?
(By the way, if anyone needs to replace your clock spring, here was a great, inexpensive source: Part# DAC/1900043 CLOCK SPRING (FREIGHTLINER) for $183.14 (shipping included) from PERIPARTS (peri-parts.com) )
Thank you for sharing your wealth of knowledge! I have learned so much from you and many others in a short amount of time being a member. What a great group.
