Service Traction Control
I have a 2012 GS, Manual, with 9000 miles on the clock. Today I arrived at work and as I put the car in reverse and started to back up, the car began running very rough and I had the following warning displayed. + the check engine light..
Service traction system
Service handling system
Hmmmm, that is strange. Since it is running rough, thinking possibly fouled spark plug, loose plug wire.
So after reading a few posts, figured the timing of it (backing up seemed to trigger it) was a bad wheel sensor, most probably. So I get home and decide to check the engine bay and low and behold, one of the spark plug wires is completely off. Hooked it back up, start car....all is well.
Thankful for an easy fix.

I had a similar issue last month. It would run fine under normal conditions but when I pushed it hard I got the same message on the DIC, and it did throw a code for a misfire. Plug wires were all connected but it turned out that there was cracked insulation on plug wire for #4 cylinder. Replaced all plug wires with MSDs and problem solved. Apparently the voltage spikes from a faulty plug firing confuse the PCM and it sends that Service Traction Control or Active Handling error message.
