1994 Nissan Sentra HOW TO RESET

On the floor, behind center console.

CLEARING CODES
Memory Erase (Single LED System)
Stored memory will be erased if battery is disconnected for 24 hours or diagnostic mode is switched
from Mode II to Mode I (modes cannot be switched with engine running). To switch from Mode II to
Mode I while in Mode II with engine off, turn diagnostic mode selector fully clockwise. Wait for at
least 2 seconds, and turn mode selector fully counterclockwise.
Memory Erase (Dual LED System)
Stored memory will be erased if battery is disconnected for 24 hours or Mode IV is selected after
Mode III has been accessed. However, if mode selector switch is turned fully clockwise, diagnostic
modes will continue to cycle until a mode is selected. This cycling does not erase stored memory.
