CHECK POINT

·

When DTC B132187 is output from the combination meter assembly, other ECUs on the same detection circuit may simultaneously output the same DTC depending on the malfunctioning area.

·

Depending on the combination of DTCs simultaneously output by each ECU, the malfunctioning area can be narrowed down. Refer to the following table for DTC combinations output by each ECU.

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 the combination meter assembly, update the ECU security key.
