Notes On Fault Tree

NOTE: Numbers in list refer to circled numbers in diagnostic flow chart, see Fig 1.
  1. If Code P112 is set current, the PCM cannot find another location to store the data, so the PCM must be replaced.
  2. Cycle the ignition to give the PCM a chance to find a place to store the data. If the code resets, no place can be found so the PCM must be replaced.
