·

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 for circuits related to this system before performing the following procedure.

PROCEDURE

1.CHECK ILLUMINATION

Check if the illumination for the radio receiver assembly, steering pad switch assembly, heater control switch or others (hazard switch, transmission control switch, etc.) comes on when the light control switch is turned to the head or tail position.

Result:

Result	Proceed to
Illumination comes on for all components except steering pad switch assembly.	A
Illumination comes on for all components except radio receiver assembly.	B
No illumination comes on (radio receiver assembly, hazard switch, heater control switch, etc.).	C
