The number below refers to the step number in the diagnostic procedures.

  1. 4

    When the TAC module detects a condition within the ETC system the PCM receives a message across serial data and more than 1 ETC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing 1 individual condition may correct more than 1 DTC. Keep this in mind when reviewing captured DTC info.
