Test Description

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

1. 1
   
   Service the ABS system before you diagnose for a misfire, because an actual engine misfire may or may not exist. The following examples illustrate how this DTC can be set with or without an actual engine misfire:
   • There was an actual engine misfire during an ABS system malfunction.
   • The vehicle operator drove on a rough road, the ABS system could not detect this due to a malfunction, and the PCM interpreted the variations in crankshaft speed caused by the rough road as a misfire.
