PROCEDURE

1.	CHECK RADIO AND DISPLAY RECEIVER ASSEMBLY

(a) Check the radio automatic station search function by activating it.

OK:

Automatic station search function stops on a station.

USE SIMULATION METHOD TO CHECK

2.	CHECK OPTIONAL COMPONENTS

(a) Check if any optional components that may decrease reception capacity, such as sunshade film or a telephone antenna, are installed.

OK:

Optional components are not installed.

NOTICE:

Do not remove optional components without the permission of the customer.

REMOVE OPTIONAL COMPONENTS AND CHECK AGAIN (SEE NOTICE ABOVE)

3.	CHECK RADIO AND DISPLAY RECEIVER ASSEMBLY

(a) Preparation for check

(1) Disconnect the RA radio and display receiver assembly connector.

(b) Check for noise

(1) Turn the ignition switch to ON with the radio and display receiver assembly connector connected.

(2) Turn the radio and display receiver assembly on and tune into AM mode.

(3) Place a screwdriver, thin wire or other metal object on the radio and display receiver assembly antenna jack and check that noise can be heard from the speakers.

OK:

Noise can be heard from the speakers.

REPLACE RADIO AND DISPLAY RECEIVER ASSEMBLY

4.	INSPECT RADIO AND DISPLAY RECEIVER ASSEMBLY

(a) Disconnect the RA radio and display receiver assembly connector.

(b) Measure the voltage according to the value(s) in the table below.

Standard Voltage:
