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

PROCEDURE

1.CHECK ILLUMINATION

Check if the illumination for the navigation 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 navigation receiver assembly.	B
No illumination comes on (navigation receiver assembly, hazard switch, heater control switch, etc.).	C
