The following directions will help you decode your 2002-2006 Nissan Altima's Service Engine Soon (SES) light and reset it.
Obtain The Trouble Code
- Turn the ignition key to the ON position and wait three seconds.
- Put the accelerator pedal to the floor and release it five times in less than five seconds.
- Wait exactly seven seconds. Put the accelerator pedal to the floor for ten seconds until the SES light flashes.
- Release the accelerator pedal and start counting flashes to obtain the four-digit trouble code.
- Long flashes (0.6 seconds) indicate the first digit of the code; count
the blinks one through nine and write down the first digit. (Ten blinks
indicates a zero.)
-
The next three digits blink
faster (0.3 second) and have a 1 second pause between digits.
- The ECM code repeats until you turn the ignition key to the OFF
position.
- You can look up the trouble codes in the Service Manual.
- If you get four blinks of ten, or 0000, the ECM indicates no malfunction.
Clear The Trouble Code
-
Clear the code and the SES light by holding the
accelerator pedal down to the floor for 10 seconds or more while the SES light is
blinking.
- When the pedal is released, the ECM will erase the trouble
code(s).
