ENTERING SELF-DIAGNOSTICS

Using (MIL)

88–94

  1. Turn ignition On.
  2. On all models except Pathfinder, Pickup and Van, proceed as follows:
    1. Turn diagnostic mode selector on ECU fully clockwise and wait until inspection lamps flash. Number of flashes displayed indicates corresponding mode.
    2. Note number of flashes, then immediately turn diagnostic mode selector fully counterclockwise.
  3. 3. On Pathfinder, Pickup and Van models, proceed as follows:
    1. Turn diagnostic mode selector on ECU to On position and wait until inspection lamps flash.
    2. Note number of flashes, then immediately turn diagnostic mode selector to Off position.
  4. On all models, when ignition is turned Off during diagnosis, in each mode, and then turned back On again after power to the ECU has dropped off completely, diagnosis will automatically return to Mode I.
  5. For description of modes, proceed as follows:
    1. Mode I (Mixture ratio feedback control monitor A): during a closed loop condition, the green inspection lamp turns on when lean condition is present and goes off when a rich condition is present. During an open loop condition, the green inspection lamp stays off.
    2. Mode II (Mixture ratio feedback control monitor B): during a closed loop condition, the red inspection lamp turns on and off simultaneously with the green inspection lamp when mixture ratio is controlled within a predetermined value. During an open loop condition, the red inspection lamp stays off. The green inspection lamp function is the same as in Mode I.
    3. Mode III (Self diagnosis): in this mode the DTC is indicated by both the red and greed inspection lamp. The red inspection lamp corresponds to units of 10; the green inspection lamp corresponds to units of one.
    4. Mode IV (Switches on/off diagnosis): during this mode, the inspection lamps monitor switch on/off condition of the throttle valve switch, starter switch and vehicle speed sensor.
    5. Mode V (Real time diagnosis): if a malfunction is present during a driving test, the inspection lamps will display the malfunction condition immediately.

READING DIAGNOSTIC CODES

The Electronic Control Unit (ECU) monitors several engine sensors and actuators. If a problem occurs the information is stored in the ECU’s memory for retrieval. The codes are displayed by the red diode on the ECU. The codes are interpreted by the number of times and duration the diode flashes. The red diode will flash for 0.6 of a second with 0.6 of a second delay between flashes “X” number of times, this will represent units of ten. Then there will be a delay 0.9 of a second and the red diode will flash for 0.3 of a second with 0.3 of a second delay between flashes “X” number of times, this will represent units of one. There will be a delay of 2.1 seconds between codes. For example, if the red diode flashes once and then flashes twice rapidly this should be interpreted as code 12. The codes are displayed in numerical order starting with the lowest and ending with the highest.

95–99

  1. Turn ignition On.
  2. Turn diagnostic mode selector on ECU fully clockwise and wait until inspection lamps flash. Number of flashes displayed indicates corresponding mode.
  3. Note number of flashes, then immediately turn diagnostic mode selector fully counterclockwise.
  4. If ignition is turned Off during diagnosis, in each mode, and then turned back on again after power to the ECU has dropped off completely, diagnosis will automatically return to Mode I.
  5. For description of modes, proceed as follows:
    1. (Mode I): with engine stopped, system in bulb check state. with engine running, system in malfunction warning state.
    2. (Mode II): with engine stopped, system in self diagnostic results state. with engine running, system in front O2S monitor state.

    1. Place ignition switch in the On position.
    2. Crank engine.
    3. Start and operate engine.
  3. The trouble codes will be displayed by the flashing Engine Control Lamp and the Overheat Warning Lamp and the Overheat Warning Buzzer.

Trouble Code Interpretation

MID-TICS System

The diagnostic trouble codes will be displayed by the check engine lamp. For example, a code 12 will be displayed by the check engine lamp flashing 1 time for approximately 1.2 seconds, followed by a .6 second pause, then 2 short flashes. Each trouble code will be displayed 3 times before the next trouble code is displayed.

Clearing Trouble Codes

What about a 2009 or earlier?

Hello there. So to me, it sounds like they left a harness unplugged when they did the trnny swap. P0101 is for the mass air flow sensor. With this unplugged, it will have little, to no power on the road. And it will keep dying in some cases. The c1708 is for you left front tire pressure sensor, and has nothing to do with your transmission. Sounds to me like a tech got carless during your tranny swap. As cor the p0456 code, it is a small evap leak detected. I would make sure your gas cap is not loose, then clear all your codes, drive it, then see what odes come back.

Recently my mechanic told me there had been a recall on my cars transmission and that I was still under original warranty. I have a 2016 Nissan Sentra. I’ve had trouble the trans was replaced, first it took two trips back to get them to take me serious that I had lost all power. They said something was loose, this a couple of months ago. It’s sounded awful since when first started, then the engine light comes on yesterday. It showed 3 codes P0456, P0101 and C1708 should I be worried? They acted like it was me, because i was 1/2 quart short on oil, although the paperwork states a quart. I don’t trust them I have barely over 100 miles to 50,000 help please. Also when I bought the car it came with a 300,000 power train warranty , I bought it used. The dealership tried immediately to get out of this.

i had problems with them to. mine was the recall on the brakes. no more Dot 3 like it said. i just bought the vehicle and whole brake system had been replaced but it had no brakes. im thinking this guy doesnt know how to bleed them so i bought it. then i find out about recall and i take it in. i explained to them that it has no brakes at all so they would know. the lady tells me well if there is no brakes at all you have bigger issues and we will have to run a $200. diagnostics test. im thinking …play me dumb? if they are going to drain and refill the brake fluid with the correct stuff they are going to have to bleed them so i told her no thnx. well my brakes are just fine now. it was like they wanted to get money out of me.
