Super DIY write up. Thank you CTS for the effort! I am planning to put vinter tyres on My Daughter's Yaris and was concerned about setting a code as she is due for Emissions and saftey inspection this november. The SW seem like a good idea. CTS You dont have to shunt any of the cut wires to keep an open antenna out of the ECU?
Does anyone know if the 14" steel rims sold through Tire rack or Discount Tire Direct will clear the calipers? Her car has optional 15 inch rims. I wish to put a 165-70 snows on the front to get better force/unit area (µN/cm2) at the contact patch. Thank you for helping, - Papa |

No shunting is required. The two wires we are disconnecting are both 12 V analog signals which the ECU is pulling through A to D converters. We shouldn't be able to pick up enough noise to cause a false signal detection. |

The Defi's micro would have to do the same thing. By the way, was the Defi VSD worth the money? For the wiring diagrams, I just have the 09 service manual. |

the second one was the VSD that would hook up to the LINK system.. this one went in the yaris. speed/tach on the windshield is awesome.. i now have a VSD-X for my xA.. it has its own screen. i had it installed for a bit then removed it. it's a nice piece but a little OTT for this build. i believe DEFI has discontinued all their HUD's.. |
