STEP 4

  • Turn the Ignition ON.

STEP 5

  • Count Multimeter needle deflections. Compare with trouble code table.
  • Each trouble code consists of two groups of one or more needle deflections.
  • Long deflections indicate the ‘TENS’ of the trouble code .
  • Short deflections indicate the ‘ONE’ of the trouble code.
  • A short pause separates each deflection.
  • A long pause separates each trouble code.
  • For example: Trouble code 12 displayed.
