For 1990-2009 cars

If a flash code has been stored, it must be cleared after the repair has been made. To clear flash codes, perform the following steps:

1. Turn the ignition switch to LOCK.
2. Remove the STOP fuse.
3. Remove the ECU-B fuse.
4. Wait 30 seconds.
5. Reinstall STOP and ECU-B fuses.
6. Turn the ignition switch ON.
7. Using the jumper, connect the DLC terminals 11 (Tc) and 3 (E1).
8. Check that the CRUISE indicator lamp flashes rapidly. This confirms that any flash codes have been cleared.
9. If the CRUISE indicator lamp flashes any flash codes, perform the cruise control diagnostic system check to determine the cause of malfunction within the cruise control system.

The cruise control system is not disabled by grounding the DLC Tc terminal. Cruise control system operation will occur normally with the exception that the CRUISE indicator will flash rapidly.
