Clearing Codes
WARNING: This page is about a different car, the 1995 Suzuki Sidekick. However, it is still accessible from the selected car via links, so may be relevant.
Only Codes 4 and 5 will store as "hard" codes. All other codes will clear as soon as fault ceases to exist. To clear Code 4 or 5, disconnect negative battery cable for at least 5 seconds.
