Toyota Corolla Cross: Entire Combination Meter does not Operate
DESCRIPTION
This circuit is the power source circuit for the combination meter assembly. This circuit provides two types of power sources; one is a constant power source, and the other is an IG power source.

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.
- Inspect the fuses of circuits related to this system before performing the following procedure.
- When replacing the combination meter assembly, update the ECU security key.

DESCRIPTION The air fuel ratio sensor (sensor 1) generates current that corresponds to the actual air fuel ratio. This sensor current is used to provide the ECM with feedback so that it can control the air fuel ratio. The ECM determines the deviation from the stoichiometric air fuel ratio level, and
