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
- Frontier, Maxima & Quest 2000 ->/Pathfinder/ Xterra 2001 ->: Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC).
- Except Frontier, Maxima & Quest 2000 ->I Pathfinder/Xterra 2001 ->: Trouble codes can be displayed by the malfunction indicator lamp (MIL) or by using a Scan Tool connected to the data link connector (DLC).
o 300ZX/Frontier/Maxima 1996 ->/Quest/ Pathfinder/Xterra: 1 [1].o Maxima ->1995: 2 [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 – except Frontier, Maxima & Quest 2000 ->/Pathfinder/ Xterra 2001 ->
- Access engine control module (ECM):
o 300ZX – 4 [1].o Frontier/Maxima – 3 [2].o Quest – 2 [2].o Pathfinder – 1 [3).
- Switch ignition ON. Do NOT start engine.
- Turn diagnostic mode selector on ECM fully clockwise [5].
- Wait at least 2 seconds.
- Turn diagnostic mode selector on ECM fully counterclockwise [5].
- 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 [6] [A].o Short flashes indicate the ‘units’ of the trouble code [6] [C].o A short pause separates each flash [6] [B].o A long pause separates each trouble code [6] [D].o For example: Trouble code 102 displayed [6].
- Switch ignition OFF.
- Self-diagnosis will return to Mode 1.
Accessing – Mode 2 – Frontier, Maxima & Quest 2000 ->/Pathfinder/Xterra 2001->
- Trouble codes can only be displayed by using a Scan Tool connected to the data link connector (DLC).
Erasing – except Frontier, Maxima & Quest 2000 ->/Pathfinder/Xterra 2001 ->
- 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 [5]
Trouble codes are erased.
Switch ignition OFF.
Turn diagnostic mode selector on ECM fully counterclockwise [5].
Repeat checking procedure to ensure no data remains in ECM fault memory.
Erasing – Frontier, Maxima & Quest 2000 ->/Pathfinder/Xterra 2001->
- Trouble codes can only be erased by using a Scan Tool connected to the data link connector (DLC).
