CAUTION / NOTICE / HINT
- NOTICE:
- ·
When replacing the combination meter assembly, always replace it with a new one. If a combination meter assembly which was installed to another vehicle is used, the information stored in it will not match the information from the vehicle and a DTC may be stored.
·When replacing of the following ECUs, update the ECU security key.
-Combination meter assembly
-ECM
·The following troubleshooting procedure is based on the assumption that the SFI system and fuel lid opener system are normal. Confirm that the SFI system and fuel lid opener system are not malfunctioning before performing the following procedure.
