DIY Cruise Control FAQ (2006-2010 Yaris)

[Yaross]

sirs, just a stupid question...

if we really wanted CC in our yaris, but our ECM was not equipped:

1. can we swapped our ECM with those that have CC already programmed in it? --or --
2. can we use our existing ecm but with some modifications?

our yaris is drive-by-wire, so there must be some other way to do it...

Only the ECM for the 1.5L engine has the built in cruise control, so if your Yaris has the 1.5, then you could swap in a USDM ECM.

The other option is to use one of the aftermarket cruise control systems. There is one system from Europe for Toyotas and I believe that the Rostra system will work with non-US Yaris.
