July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Rough Terrain Signal

Rough road signal and related circuits are monitored by ECM. When ABS/EDL recognizes wheel spin on one wheel ECM switches Misfire Recognition function off. It is possible that a Misfire DTC will also be stored along with DTC P1606. This is due too a sequencing error, and should be ignored.
