Clearing and Reading Diagnostic Trouble Codes

If a DTC has been stored, it must be cleared after the repair has been made. To clear DTCs, perform following steps.
1. Turn ignition switch to LOCK.
2. Remove STOP fuse.
3. Remove ECU-B fuse.
4. Wait 30 seconds.
5. Reinstall STOP and ECU-B fuses.
6. Turn ignition switch to ON.
7. Using jumper, connect DLC terminals Tc and E1.
8. Check that the CRUISE indicator lamp flashes rapidly. This confirms that DTCs have been cleared.
9. If the CRUISE indicator lamp flashes any DTCs, perform the cruise control OBD system check to determine 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.
