Still Doesn’t Work?

If you have bought a paddle shift steering wheel and the paddles don’t work, it could be the wiring.

Martjin D found that his 2007 model didn’t have the paddle shift wiring from the steering wheel to the speedo. Once these wires were added, the paddles could be coded as expected. See the 451 steering wheel wiring diagram here.

If you have the wiring already, Smart also altered the wiring when they face-lifted the 451 in September 2010. If you fit a pre facelift wheel to a post facelift car or vice-versa, it will not work until you swap the 2 wires over. Both wiring diagrams for each year variation can be seen here.

How Do I Know Which Wheel I have?

Time to break out the multimeter and get testing. The connections are the same betwewen the 2 except for the paddles so put your multimeter on resistance checking and put the probes on pins 5 and 10 and look at the readout on the multimeter. If you get about 8kΩ then they are the correct pins. If you get no reading, place the probes on pins 8 and 9 and you should see the 8kΩ show up on the multimeter.

Remember what 2 pins your paddles where using. Probably best to write it down.
