"Once you eliminate the impossible, whatever remains, no matter how improbable, must be the truth." - Sherlock Holmes
96 & later are OBD2 systems and require a scantool Note: We are finding that some 94 & 95 Toyota vehicles are OBD2
compliant and require a scan tool. Check your emissions decal under the hood to confirm if you have an OBD2 compliant vehicle.
NOTE: Not all trouble codes will activate MIL (CHECK ENGINE light)

Clearing Trouble Codes
All trouble codes must be purged from the ECUs memory after repairing the faults. Otherwise, code(s) would remain in the ECUs memory indefinitely and would
appear along with a new code in the event of a future problem.
Remove the EFI fuse (15A) for 30 seconds with the ignition switch OFF to clear any codes. It may take longer than 30 seconds, depending on ambient temperature
(the lower the temperature, the longer the fuse must be left out).
Trouble codes can also be cleared by disconnecting the vehicle battery. However, other memory functions (clock, radio, etc.), will need to be reset.
After the codes are cleared, road test the vehicle (as applicable for the fault) and recheck if any codes reset. If so, it indicates that the trouble area has not been
repaired correctly.
