General information

  • Engine control module (ECM) incorporates self-diagnosis function.
  • Malfunction indicator lamp (MIL) will illuminate if certain faults are recorded.
  • ECM operates in backup mode if sensors fail, to enable vehicle to be driven to workshop.
  • Sentra ->1999/all other models ->2000: Trouble codes can be displayed by the malfunction indicator lamp (MIL) or by using a Scan Tool connected to the data link connector (DLC) 1 [1] or 1 [2].
  • Sentra 2000 ->/all other models 2001 ->: Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC) 1 [1].

NOTE: The use of a Scan Tool is essential to obtain full diagnostic information.

Accessing – Mode 1

  • Switch ignition ON.
  • Check MIL illuminates.
  • Start engine. Allow to idle.
  • If MIL extinguishes, no trouble codes have been recorded.
  • If MIL remains illuminated, access trouble codes.

Accessing- Mode 2- Sentra ->1999/all other models ->2000

  • Access engine control module (ECM):
o 200SX/Aitima/Frontier/Sentra/Xterra – [1] [3].
o 240SX – [2] [2].
o Pick-up – [3].
  • Switch ignition ON. Do NOT start engine.
  • Turn diagnostic mode selector on ECM fully clockwise [4].
  • Wait at least 2 seconds.
  • Turn diagnostic mode selector on ECM fully counterclockwise [4].
  • Self-diagnosis now in Mode 2.
  • MIL should flash.
  • Count flashes and compare with trouble code table.
o Long flashes indicate the ‘hundreds’ of the trouble code [5] [A].
o Short flashes indicate the ‘units’ of the trouble code [5] [C].
o A short pause separates each flash [5] [B].
o A long pause separates each trouble code [5] [D].
o For example: Trouble code 102 displayed [5].
  • Switch ignition OFF.
  • Self-diagnosis will return to Mode 1.

Accessing – Mode 2 – Sentra 2000 ->/all other models 2001 ->

  • Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC) 1 [1].

Erasing – Sentra ->1999/all other models ->2000

  • Trouble codes can be erased by using a Scan Tool connected to the data link connector (DLC) or as follows:
  • With the ignition switch ON and the engine control module (ECM) in diagnosis test mode 2.
  • Turn diagnostic mode selector on ECM fully clockwise [4].
  • Trouble codes are erased.
  • Switch ignition OFF.
  • Turn diagnostic mode selector on ECM fully counterclockwise [4].
  • Repeat checking procedure to ensure no data remains in ECM fault memory

Erasing – Sentra 2000 ->/all other models 2001->

  • Trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC).
